Intra Vas Device

Filed under: Reproductive Medicine

Here is something new in male contraception to watch for. Shepherd Medical Company reports that "... the US National Institutes of Health (NIH) has awarded the company a $1.4 million USD grant to conduct human clinical trials on its proprietary Intra Vas Device (IVD)":

The IVD, is a flexible, hollow, silicone plug that is inserted into the vas deferens tubes (in men) to block sperm transport. Preliminary studies in primates and humans have shown that the device has the potential to be as effective as vasectomy. The preliminary studies on primates have also supported that the device could be easily removed and sperm flow reestablished. Currently, trying to reverse a vasectomy is precarious and very expensive with pregnancy rates at only 50-60%.

The IVD is implanted in a simple outpatient procedure under local anesthetic in a doctor's office. IVD insertion will involve accessing the vas deferens tubes much like during a vasectomy, except rather than cutting and cauterizing the tubes, thereby permanently damaging them, only a small opening is made in each tube, to insert two silicone plugs. The tiny opening is expected to heal completely and rapidly. It is anticipated that the IVD can later be removed in a similar procedure to its insertion, reestablishing sperm flow. The IVD has the potential to become an attractive alternative to standard vasectomy...

Dr. Neil Pollock, co-founder and director of Shepherd Medical Company, has a personal website where additional information about IVD can be found...

UPDATE (01/31/05):

The Canadian Press interviews Neil Pollock and has additional info on IVD...

The Wavefront Analysis

Filed under: Ophthalmology

In case you've missed it, it is Cataract Awareness Month. Cataracts are a common problem among elderly, diabetics, etc. One of the most common ways to treat cataracts involves surgery, during which a new intraocular lens is implanted. The Atlanta Journal-Constitution reports about new advances in ophthalmology being made, one of which involves the use of a technology called wavefront analyzer, that one day might allow the manufacture of intraocular lenses designed for each individual patient:

Testing is under way on a further refinement involving a device called a wavefront analyzer. The device measures the way light travels through a cataract patient's entire optical pathway, then compares it to the way light travels through an optically perfect eye.

The information from this device can be used to create lenses crafted to address the specific irregularities of a person's visual system.

"That's still in the testing stages, but it could eliminate some of the distortion that patients complain of," Steinemann said.

WaveFront Sciences, Inc. is one of the manufacturers of ophthalmic wavefront analysis systems. If you are curious about the science of wavefront analysis, the company provides an explanatory webpage. If you want to see WaveFront Sciences' wavefront analysis system, check out this page...

The Bright Future of Nanomedicine

Filed under: Nanomedicine

WaPo finds the future of nanomedicine to be very promising: "Nanomedicine's Promise Is Anything but Tiny."

Quantum dots, also known as "qdots," are bits of material -- silicon, for example -- that are so tiny they are in some cases just a few atoms across. Illuminated by ultraviolet light, they glow very brightly with a specific hue that depends on their size: qdots with diameters of about 2 nanometers (billionths of a meter) glow bright green, for example; 5 nanometer dots glow brilliant red.

Scientists are already using quantum dots as research tools to help them understand how proteins, DNA and other biological molecules catch rides on the various transportation systems inside cells. First they coat some qdots with a material that makes the dots attach specifically to the molecule they want to track, then they inject those coated dots into cells growing in laboratory dishes. Once the dots grab their targets, researchers simply watch the trails of colored light to see where they go.

Qdots shine brighter and longer than conventional dyes used to illuminate the inner workings of cells. And by coating different size qdots so each attaches to a different kind of molecule, scientists can track the movements of many substances in a cell at once by following the various color trails.

Now scientists are developing qdots not just for basic research but to diagnose diseases.

There are scores of proteins and other substances in the body that are early indicators of disease but which are difficult to detect with current technologies. While qdots and other nanomaterials have not been proved safe for use in the body, they are clearly capable of spotting diseases in blood or tissue specimens. Qdots that bind to proteins unique to cancer cells, for example, can literally bring tumors to light.

Biochip for inflammatory bowel disease

Filed under: Diagnostics , GI

Crohn's disease and ulcerative colitis are two most common forms of inflammatory bowel disease (IBD) -- an inflammation of the digestive tract. BasqueResearch.com informs that a Spanish company Progenika has developed a biochip to diagnose genetic mutations related to inflammatory bowel disease:

At the III International Symposium on Advanced Therapy for Chronic Inflammatory Bowel Disease, held in Madrid, the biotechnological company, Progenika, presented a DNA-chip the purpose of which is the optimisation of the diagnosis, prognosis and treatment of patients with inflammatory bowel disease (Crohn's disease and Ulcerous Colitis).

The project developing the biochip, known as the IBDChip, was carried out with the collaboration of Dr. Miquel Sans of the Gastroenterology Service at the Barcelona Hospital Clinico and Dr. Carlos Cara of UCB Pharma. The biochip is currently analysing 46 mutations related to inflammatory bowel disease (EII) and will shortly begin clinical trials.

The polymorphisms analysed are diverse and enable the establishment of the risk of suffering from the disease, its prognosis and the response of the patient to the pharmacological treatment.

From a clinical practice viewpoint the implantation of the IBDchip has a twin usefulness: it enables the selection of the most suitable therapy for each patient and it also determines, in those family members of EII sufferers who wish to be tested, the degree of predisposition for developing the infirmity.

New method of gene delivery using lasers

Filed under: Genetics , etc.

The purple laser developed by scientists at St Andrews and the 'new' cells.

The University of St Andrews reports about a new way to deliver genes intracellularly using a purple laser:

Leading laser scientists at the University of St Andrews have developed a new method of delivering genes to cells using laser light. The new technique, which is cheap and powerful, could have important implications for future studies in biomedicine and healthcare.

Optical technology has huge potential for novel developments in the bio-medical field and St Andrews has outstanding research groups in this area. The new method - which involves a miniature violet laser - is cheap, simple, powerful and versatile. Its adaptability means it could have potentially wide medical applications including gene therapy, the delivery of anti- cancer agents and advanced studies of neuro-degenerative diseases.

...

The new technique involves the violet laser being focused onto cell membranes for a fraction of a second - this causes the membrane to open up, allowing foreign genes to enter. The cell's internal mechanism causes the membrane of the cell to heal itself thus appearing to suffer no long- lasting damage. After inserting the genes, the team grew the cells, which appeared to remain healthy and multiplied normally. The presence of the inserted gene in the multiplied cells was then confirmed by observing the red/green fluorescent proteins produced by the 'new' gene.

Palatal Implant System

Filed under: ENT

Reuters reports:

NEW YORK (Reuters Health) - Insertion of small plastic rods into the soft palate with a minimally invasive surgical procedure is a safe and effective treatment for snoring, a small study suggests.

The recently developed Anti-Snoring Device, now called the Pillar Palatal Implant System, uses a device that looks somewhat like soldering gun to insert a thin 3/4-inch-long plastic rod into the soft palate under local anesthesia. Typically, people have three implants inserted.

Dr. Joachim T. Maurer, from the University Hospital Mannheim in Germany, and colleagues assessed the outcomes of 15 people who were treated with the device.

After 90 days, there was a significant improvement in snoring-related symptoms, the authors note in the medical journal Otolaryngology-Head and Neck Surgery. Moreover, the average number of snoring sounds per hour fell following treatment.

Restore Medical, Inc. provides additional information about implants that it has developed:

The Pillar Procedure involves the placement of three tiny woven polyester inserts that stiffen the structure of the soft palate to help reduce both the vibration that causes snoring and the ability of the soft palate to obstruct the airway.

Rather than surgically removing tissue, the Pillar Procedure is designed to stiffen the soft palate. Once in place, the inserts add structural support in the muscular layer of the soft palate and induce a natural tissue response that secures them within the palate. Over the next 8-12 weeks, fibrosis creates additional stiffening and structural support of the soft palate.

In the works at Sandia N.L.

Filed under: Diagnostics , Nanomedicine

Here is an interesting nanotechnology being developed at the Sandia National Laboratories:

A five-pound, hand-held medical diagnostic device being developed at the National Nuclear Security Administration's Sandia National Laboratories promises to be this ticket to better health for millions of Americans.

"We have taken technology that we've worked on for several years -- Sandia's lab-on-a-chip devices -- and are adapting them for use in medical diagnostics," says Anup Singh, project lead. "We've tested saliva samples from healthy patients for gum disease, and within the next few months we will begin using the diagnostic tool to test diseased samples."
...

As part of the immunoassay process, antibodies specific for biomarkers of interest, such as gum or heart disease, are tagged with a fluorescent dye and then mixed with a patient's saliva or blood. Biomarkers present in the sample attach themselves to the fluorescent antibody. The mixture is injected into a microchip using a syringe. An applied electric field forces the sample to flow through a microchannel that is two to five centimeters long, tens of microns deep, and a few hundred microns wide.

As the sample moves through the channel, cast-in-place porous polymers in the microchannel sort molecules based on their sizes and electrical charges. If biomarkers for the disease are present in the patient's sample, the lab-on-a-chip analysis will separate fluorescent antibodies bound to the biomarker from unbound antibodies.

A photomultiplier tube then detects the fluorescence emission with extreme sensitivity. After quantifying the relative fluorescence of the two species -- bound and unbound antibodies -- researchers can determine the amount of biomarker present in the patient's sample. If the sample contains significant fluorescence emission from a bound antibody, indicating that biomarkers are present above a certain level, a doctor could conclude that the patient has or will eventually get the disease for which he or she is being tested. At the conclusion of the test, while the patient is still in the doctor's office, preventive or therapeutic care could begin.

The Ether Monument

Filed under: the good old days...

The Ether Monument is a 40 foot tall sculpture that commemorates the first demonstration of general anesthesia at Massachusetts General Hospital on October 16, 1846. This sculpture is located at the Boston Common, and it is the only sculpture in the park that commemorates an event, rather than an individual. The inscription taken from the Book of Revelation reads: "Neither shall there be any more pain."

Dr. Leroy D. Vandam, former chairman of anesthesia at Harvard's Brigham and Women's Hospital (the department where I have served as a resident for 3+ years -- exposed to Harvard's superinflated egos) had written a superb, well-researched essay titled "A History of Anaesthesia at Harvard University". A sample quote:

THE AMERICAN CONCEPTION

Within a span of four years in the US, anesthesia was born. Why did several people develop the same idea? Owsei Temkin had written: "Sociologists of science have cited in evidence for social causation the multiple appearance of the same discovery, "Multiples" in the language of Robert Merton. The independent use of anesthesia by Long, Wells and Morton is a classical example of this tenet. "Though discoveries are not necessarily ideas, both are spoken of as being "in the air". Both regional and then intravenous anesthesia would ultimately pursue similar courses.

5 Minutes Thursday: Medgadget Investigates

Filed under: etc.

Remember the story, reported here at Medgadget on January 17, about the first Iowan to receive a new electronic heart implant? The device that was implanted was the InSync Sentry™ ICD with OptiVol™ Fluid Status Monitoring: a cardiac resynchronization therapy device combined with an automatic fluid status monitor.

Surprisingly, this morning Long Beach Memorial Hospital, in a press release announced their intention to "implant world's first device to manage the heart's fluid accumulation". It turns out that this is the very same InSync Sentry device implanted in Iowa ten days ago. For clarification, we contacted Jeanne Randol, a spokesman for the Long Beach Memorial Medical Center, and she was unable to resolve the implication that their institution was the first to perform the procedure. The hospital did report that the implantation was completed successfully today and the patient is recovering.

Reciprocating syringe from Avanda

Filed under: Medicine

It has come to our attention, that the U.S. Food and Drug Administration has approved two versions of the reciprocating syringe from Avanca Medical Devices. The company is a spin-off of the University of New Mexico. Here is additional info about the syringe:

In procedures such as biopsies and spinal taps, where a doctor uses one hand to feel the body or adjust instruments, he must use his other hand alone to pull the syringe's plunger out - typically by pushing against suction of the patient's body with just his thumb.

If the pressure of the awkward motion makes his hand shake or jerk, the patient is the one to suffer - with extended hospital stays or additional pain, said Sibbitt, who thinks he has solved the problem by creating a new type of syringe.

...

To fight the problem in his own practice, Sibbitt started tinkering with conventional syringes to come up with something new - a two-buttoned syringe that uses a pulley system to lift the needle out of the patient as the doctor pushes down on a second button, rather than trying to lift a single one with his thumb.

"Hands, their strength is grasping things," Sibbitt said. "The weak part is extension of the fingers and stretching. The reason this new syringe works is it uses the strengths of the hand by letting the thumb clench the button."

Sibbitt had 22 doctors try his test on the foam pad with both a conventional syringe and the new type he invented. All of them performed significantly better with the two-buttoned syringe - called the reciprocating syringe, he said.

"On a zero-to-10 scale the physicians rated the conventional syringe as a 2 and the new syringe as a 9," Sibbitt said. "They just didn't know something like this could be made."

Cell phones @ hospitals (an update)

Filed under: Society

KCRA-TV of Sacramento, CA reports:

Soon, visitors at Sacramento's Sutter Memorial Hospital will be able to use cell phones in patient rooms.

"We have a body of experience that, with a few exceptions, cell phones don't create a risk to patients," said Sutter engineer Jon Rice.

For years, it was thought that radiation from cell phones interfered with hospital equipment. But new research shows current cell phones don't seem to be a problem.

"Sutter tested much of its medical equipment with cell phones, and our testing process indicated there were no problems as long as the cell phone was 3 feet away from the medical device," Rice said.

But it's the fear of interference that's keeping other Sacramento hospitals from lifting their cell phone bans. And there are other issues to consider, like the disruptions.

"It is an issue with patient privacy. Patients' medical conditions may be inadvertently disclosed to people who shouldn't know anything about that information," said KCRA HealthWatch 3's Dr. Tom Hopkins.

And how does one enforce a no-cell phone rule anyway?

FYI, the British Medical Journal has called for a revision of current guidelines of cell phone use in hospitals in March, 2003 issue. The controversy, however, still lingers...

The CLiRpath system

Filed under: Vascular Surgery

The Detroit News reports that Dearborn's Oakwood Hospital is one of few hospitals in the country to perform a procedure, called CLiRpath, for treatment of peripheral vascular disease.

According to Spectranetics, the manufacturer of the laser system, the device has been FDA approved. Furthermore:

Current alternatives to treat refractory total occlusions common in advanced arterial disease are limited, and "treatment" often is amputation. With a 95% limb salvage rate* among survivors, the new CLiRpath system gives your CLI patients with total occlusions not crossable by a guidewire, a viable alternative in the fight against amputation. Used in conjunction with the CVX-300® laser system, CLiRpath Extreme® Catheters use "cool" ultraviolet excimer laser energy to cross total obstructions and restore straightline blood flow to the foot, which may facilitate wound healing.

The CVX-300 excimer laser is a pulsed system that vaporizes plaque and thrombus by delivering very high energy in extremely short pulses. The "cool" excimer laser ablates tissue on contact (about 50 microns from the catheter's tip) without inducing thermal damage to the treated artery.

Debulking with CLiRpath prior to balloon angioplasty transforms total occlusions not crossable by a guidewire and diffuse multilevel disease into more easily ballooned stenoses.

Great system, indeed. One of the most common methods to unblock thrombosed artery nowadays is to use a so-called Fogarty catheter (wire with an inflatable balloon at the tip), to surgically bypass the obstruction, or to amputate. One does not have to be a doctor to realize how sucky these options are.

Ludite or Moonbat?

Filed under: Society

In the article published at The Staten Island Advance, Dennis Bloomfield, M.D. (who describes the start of his career prior to 1950s!) reminds us that the magic touch is disappearing:

But in my mind, the very technology that propelled American medicine to the forefront is changing the methods of teaching and the expectations of both patient and doctor, no all to the good.

The cost of the CAT scans, MRIs, internal pacemakers, kidney dialysis, coronary artery angioplasty and surgery -- and the list goes on and on -- is becoming prohibitive in this constricting economy and defacto rationing of medical services, so obvious in Canada, is heading south. Physicians are losing their confidence in their physical examination capabilities and are more inclined to send patients for expensive and time consuming tests, performed by machines and reported by doctors who never see the patients, than by undertaking meaningful histories and hands-on examinations.

The practice of medicine is losing that magical and therapeutic special human relationship between doctor and patient and there is no time in medical school, with so much to learn, to imbue that relationship with any sort of value. It is forecast that, in just a few years, surgeons will have lost the skill to examine patients to make diagnosies and will feel and be taught that laboratory tests are not only good enough but that hands-on examination is not worthwhile.

In the distant past, medical diagnosis and treatment was mired in religious incantations and mythical practices. In the near future, it might well be just as much in trouble in the hands of fantastic but inhuman, cold machines. As in just about every aspect of life, the good old days seem always to be in the past.

The other scary aspect not thought through in the article: dehumanizing technology prolongs lives, and so the longer-living patients suffer the absence of the magic touch for a longer time. Ha!

SPY™ Intra-operative Imaging System for CABG

Filed under: Cardiac Surgery

The press release from Novadaq Technologies informs that the company's SPY™ Intra-operative Imaging System has received 510(k) clearance from the FDA for use during coronary artery bypass surgery (CABG):

The SPY Intra-operative Imaging System is the first fluorescent imaging system available for use during CABG. SPY enables cardiac surgeons to simply and efficiently confirm proper placement of their bypass grafts and assess the functionality of those grafts while the patient is still on the operating room table. Use of Novadaq's SPY Imaging System may potentially reduce the number of patients that must return to the operating room for the revision of improperly functioning or potentially misplaced grafts.

The system relies on ICG (indocyanine green), that has to be injected IV in order for a sensor to detect fluorescence. As a cardiac anesthesiologist, I can assure that using this system will be welcomed: current use of Doppler ultrasound to detect the flow inside coronaries and grafts (by listening to it!) is totally outdated.

This system surely reminds us of an experimental Vein Contrast Enhancer, that supposedly does not use any contrast agents, unlike the SPY system.

Otogram

Filed under: Diagnostics , ENT

The Houston Business Journal reports that Houston Angel Network (a.k.a. HAN -- an exclusive group of high-net-worth individuals, or angels, who invest in promising start-up companies) has secured buy-out of Tympany Inc. by Sonic Innovations, apparently making money in the process. What impressed those angels in Houston is the Otogram, the system to self-administer a hearing test:

The Otogram™ uses artificial intelligence, touch-screen technology, and proprietary hearing testing equipment to allow patients to self-administer the hearing test, after brief instructions from an administrator. The Ambient Noise Management System™, combined with specialized foam ear inserts, allows testing in any quiet examination room, without the need for a sound booth. The test can be conducted in multiple languages, including English, Spanish, Russian, Mandarin Chinese, Vietnamese, and Korean. Upon completion of the test, the patient's results are printed in a computer-generated standardized easy-to-read report and can be integrated with electronic medical records.

The Otogram™ guides a patient through the following diagnostic hearing tests in approximately 20 minutes:

-- Comprehensive audiogram which includes pure-tone air and bone conduction with masking, speech reception threshold and speech discrimination;
-- Tympanometry
-- Acoustic reflex
-- Otoacoustic emissions (DPOAE)

SIMpill

Filed under: Geriatrics , Medicine

The Business Day of Johannesburg, South Africa reports about SIMpill, the SMS-driven pill bottle that through a cell phone reminds patients to take their meds:

A local doctor has developed a pill bottle that uses cellphone technology to remind patients to take their medicines and warns them if they are about to take an extra dose by mistake.

The SIMpill device is aimed at patients on long-term medication for diseases such as tuberculosis (TB), HIV, epilepsy, diabetes and asthma, for whom missing even a few doses can have potentially life-threatening consequences.

For example, patients with infectious diseases such as HIV and TB may become drug-resistant, and epilepsy patients risk seizures if they skip pills, said SIMpill inventor Dr David Green.

The patented bottle contains an electronic chip that sends an SMS to a secure central server when the cap is removed. The SMS includes a unique pill box identification number.

If the SMS arrives too early or too late, the server sends a reminder to the patient's cellphone, or one belonging to a family member or health-care professional. "Unlike alarm clocks, which often sit on the shelf and beep unnoticed, cellphones tend to be carried around," said Green.

The patients' pill-taking schedules were programmed into the tamper-proof pill bottles by the pharmacist who dispenses their medicines, said Green.

Patient rounds with robodoc

Filed under: Telemedicine

The Record of North Jersey reports about Mr. Rounder, a mobile robot at Hackensack University Medical Center, that allows doctors to make patient rounds via teleconference:

It was a casual Friday at the hospital, and Mr. Rounder wore his white doctor's smock with the collar open.

On his way into Room 3001, Mr. Rounder bounced off the door frame but recovered in time to greet the patient, Bruce Davidson, and his wife, Marsha.

The RP-6 robot, called Mr. Rounder by co-workers, looks like a portable television set mounted atop an industrial floor buffer. The smiling face on its 15-inch TV screen on this day was that of Davidson's physician, Dr. Garth H. Ballantyne, chief of minimally invasive surgery at the hospital.

Ballantyne was in his office on another floor in another building of the hospital monitoring the Davidsons through a tiny camera on Mr. Rounder's "head"; images were transmitted back to Ballantyne's laptop.

He commanded the robot from a laptop computer on his desk, over the Internet and the hospital's wireless system. The battery-powered device rolls along on three billiard-size polyurethane balls and digitally "walks and talks" in real time.

The Davidsons and their robo-doc conferred in the room like it was any post-operative examination. Mr. Rounder's bedside manner is personal and professional, if you don't mind having a consult with the Mars rover.

Mr. Rounder is the product of InTouch Health of Santa Barbara...

P.S. The question has been raised whether Mr. Rounder has tied up Mrs. Marsha Davidson. Who knows...
