Our fingertips are incredibly sensitive biomechanical devices. They're regularly used by physicians to feel out tumors during biopsy or excision surgeries. While reasonably effective, too many patients return for repeat procedures to remove missed bits of target lesions. Researchers at University of Western Australia have been working on giving superpowers to surgeons' fingers so they can better discern healthy from cancerous tissues. The team built a quantitative micro-elastography (QME) probe that relies on optical coherence tomography to detect how tissue gives way under stress. It has a fiber optic cable whose tip...
Alzheimer's disease has no cure at this point. Only a few therapies that try to slow the progression are available, but there's a light, and some sound, at the end of the tunnel. Researchers at MIT and Georgia Tech have now shown they can reduce the buildup of amyloid plaques in mouse models of Alzheimer's disease using nothing but light and sound. Moreover, they were able to achieve a notable improvement in the mental abilities of the mice. Previously, auditory gamma entrainment using sensory stimuli (GENUS), a technology that uses...

Lantos Technologies, a company out of Wilmington, Massachusetts, is releasing the first FDA-cleared 3D ear scanner that can image everything from the outer ear to the ear drum. The Lantos 3D Scanning system is used to alleviate the need for silicone impressions when making hearing aids and other custom-made hearing products. Each scan produces about a million data points, which results in a highly detailed volumetric representation of the ear. It uses a special membrane to perform the scan that helps to avoid artifacts that can result from moisture, hair, and...
Itamar Medical, an Israeli firm, released the latest model of its WatchPAT sleep apnea detection system. It's indicated for use by patients at home to help clinicians diagnose sleep apnea without requiring a visit to the sleep lab. It uses Itamar's Peripheral Arterial Tone (PAT) technology, which involves measuring the arterial tone changes in peripheral arterial beds.  This data, along with that coming from an accompanying pulse oximeter and heart rate sensor, lets an algorithm detect obstructive as well as central sleep apnea. The new WatchPAT 300 doesn't require any nasal canula or chest...
Surgeons working on delicate areas and visible areas of the body, particularly in plastic and cosmetic surgery, have to keep in mind the direction of skin tension lines. These are formed by collagen fibers that are aligned within the dermis of the skin. If incisions are made against the grain, more visible scars will be a result. Sometimes it's hard to tell the direction of skin tension lines, so there are printed surface maps that are used, but individual patients may have their tension lines grow differently than in most...
Interface Biologics Inc (IBI) is a company from Toronto, Ontario, Canada that develops innovative materials for both Medtech and Pharmaceutical applications. Their Surface Modification Technology is called Endexo, which are fluorine-based additives which migrate to the top 10 nanometers of device surface and prevent platelet adherence and activation in blood contacting devices and reduce bacterial adhesion and biofouling in non-blood contacting devices. The Endexo additive technology has significant advantages over competitive technologies – including heparin coatings.  These include manufacturing advantages (no change in the manufacturing process, low cost technology, compatibility...

Researchers from Stanford University have developed a new tool to track patient recovery in a hospital setting. They have created a deep learning-based system to see if patients are able to perform mobility tasks, such as getting in and out of bed or sitting in a chair. In an ICU setting, improved mobility is associated with better recovery, quality of life, and overall survival. In partnership with Intermountain LDS Hospital ICU, in Salt Lake City, Utah, the researchers set up depth sensors in eight patient ICU rooms. The team chose...
The majority of bone implants, cements, and grafts are hard objects that don't always work well in filling the space they're supposed to inhabit. Soft objects can gently expand and relocate their mass evenly over a volume, and they tent to be less dense so as to leave room for cells to make home inside of. Researchers at the University of British Columbia and McMaster University in Canada have just reportred on a plant cellulose-based bone scaffolds that can be injected into areas of damage. The material allows native tissue...
The concentration of dopamine in a patient's blood can be an important biomarker for a variety of diseases, including certain cancers, depression, and Parkinson's. Measuring dopamine in whole blood still requires a laboratory, making it slow and expensive and not always suited for things like screenings. Scientists at the University of Central Florida have now developed a portable, enzyme-free dopamine detector that takes just a sample of blood and which provides in a matter of minutes. It is hoped that the technology will be available for point-of-care applications, potentially making...
Robots that help severely disabled people are generally assumed to have to be super smart, capable of replacing human caretakers. Engineers at Georgia Tech decided to take a very different approach, instead empowering disabled people to control the robots that help them. The technology allows disabled people to see what the robot is seeing, since a video feed is passed from the robot's cameras to the bedside computer. It also allows for careful, planned control of the robot's movements. The robot used was the PR2 mobile manipulator from Willow Garage, a Silicon...
Siemens Healthineers won clearance from the FDA for its Mobilett Elara Max X-ray system. The mobile device can be wheeled from room to room while the cables are safely hidden inside and the antimicrobial coating prevents the transfer of pathogens. The firm touts the system's IT security features that help to maintain patient privacy while being compatible with a hospital's own IT systems. It can be used to access previous scans and other patient data right at the bedside, helping clinicians to maintain continuity of care. This is thanks to a...
