Wearable biomedical devices hold the promise of allowing for continuous, remote patient monitoring in all kinds of settings. A variety of vital signs, including heart rate and its variability, body temperature, and the amount of sweat produced, can be measured. The problem is that a lot of these measurements are not particularly accurate when using devices that are made to stick to or wrap around a part of the body. The sensors tend to not conform to the skin as it flexes and move slightly along the skin, generating a...Read More
The need for emergency medical services (EMS) outside of the hospital setting is on the rise, with an estimated 240 millions 9-1-1 calls made in the US annually. While medical equipment used in this setting must be available, manipulable, and able to share important data across a variety of unknown situations, historically it has been cumbersome and limited in its connectivity. Philips' Tempus ALS solution including the Tempus Pro monitor (left) and Tempus LS defibrillator (right). Global healthcare technology company Philips is seeking to address the needs of the EMS...Read More
A good deal of orthopedic bone repair surgeries involve injecting powders or pastes, to serve as scaffoding, into fractures. Now a collaboration between scientists at Oregon Health & Science University (OHSU), University of Oregon, New York University, and Mahidol University in Thailand has led to the development of a Lego-like 3D printed scaffolding system that may turn out to be much easier to use and clinically more effective for treating complex bone fractures. The tiny 3D printed cubes, which are only 1.5 mm on each side, are designed to hold...Read More
A team of researchers from Purdue University and the Indiana University School of Medicine has recently developed and now demonstrated, in realistic simulations, a telemedical augmented reality system that can be used in very difficult and stressful situations. Called System for Telementoring with Augmented Reality (STAR), it allows remote clinicians, such as surgeons, to guide military medics, paramedics, and others in how to perform emergency procedures. The STAR system revolves around an augmented reality headset that's worn by the person on the scene. Video from a forward facing camera on...Read More
People stricken with COVID-19 exhibit a wide range of symptoms. Some are barely affected while others suffer dire consequences. People with asthma are in particular danger, as SARS-CoV-2 is a respiratory virus that can make breathing even more difficult. Now, the FDA has issued an Emergency Use Authorization for the gammaCore Sapphire CV non-invasive vagus nerve stimulator (nVNS) to help adult asthmatics with COVID-19 (or those suspected of being infected) overcome difficulties breathing when drugs are not appropriate or are insufficient. The gammaCore stimulator has been approved as a treatment...Read More
Protaryx Medical, a company based in Baltimore, Maryland, has developed a device to allow for more precise transseptal access to the left atrium during transcatheter procedures. The device provides three-dimensional control and steerability to take the guesswork out of transseptal access to the left atrium, and the company believes that this could improve physician convenience and reduce the chances of complications during such procedures. Transseptal access to the left atrium is required during several transcatheter procedures, including repair or replacement of mitral valves, catheter ablation therapy, and closure of the...Read More
Palliare, a company out of Galway, Ireland, won FDA clearance for its flagship product, the EVA15 insufflator and smoke evacuation system. The EVA15 combines two devices into a compact package that is designed for use in laparoscopic, endoscopic, endolumenal, and robotic procedures. Smoke is a common problem in all kinds of minimally invasive procedures that involve ablation, cauterization, and other kinds of tissue manipulation. Smoke makes it difficult to see the surgical scene, but it can also be harmful to the clinicians that end up breathing in the soot. According...Read More

Guide dogs can be incredibly helpful, letting blind people maintain a level of independence that would be difficult without their loyalty. However, guide dogs require a huge amount of training and, because they're dogs, are not practical for every blind person. Now, a student at Loughborough University in England has designed a concept handheld device that can do some of the tasks of a guide dog. The electronic tool is called Theia and it features gyroscope-based technology to pull the user in the correct direction. This is similar to how...Read More

Optical coherence tomography (OCT) is an imaging technique regularly utilized by ophthalmologists to view multiple layers of the cornea and count the nerves and cells within. It's important for diagnosing a variety of corneal conditions as well as when preparing for cataract surgery. The problem is that, as anyone who has tinkered with macro photography knows, it's very difficult to obtain a sharp image of a large section of a curved surface such as the cornea. Now a team of collaborators in France has developed an exciting new OCT imaging...Read More
Boston Scientific's WATCHMAN, a device that's used to close the left atrial appendage, has done wonders for preventing the formation of clots that lead to stroke in many patients. Now the company has announced that its WATCHMAN FLX, a new and much improved version of the implant, won FDA approval. Already cleared in the European Union, the WATCHMAN FLX is indicated for patients with non-valvular atrial fibrillation (NVAF) for whom oral anticoagulants are not sufficient. The new minimally invasive implant can be recaptured, repositioned, and redeployed until proper placement is...Read More
Upper arm prostheses that give their users a sense of touch have been developed in the past (see flashbacks below). These require careful surgical placement of electrodes near the remaining nerves within the stump and precise stimulation of said nerves. Now researchers at the University of Pittsburgh have achieved a remarkable feat of using existing spinal cord stimulators, usually used to treat chronic pain, to produce a sense of touch in the missing limbs of amputees. This can certainly be used to give upper arm prostheses the ability to produce...Read More
