SX-One MicroKnife Makes Carpal Tunnel Release a Minimally Invasive Procedure: Interview with CEO Dr. Darryl Barnes

Carpal tunnel syndrome is a fairly common diagnosis in the United States, affecting approximately three to six percent of adults. Symptoms include pain, numbness, and tingling along the thumb, index, and middle fingers. For severe or refractory cases, the best treatment is surgery. However, because open surgery requires anesthesia and many weeks of (Read more...)

Iris Needle Guidance for Lumbar Punctures: Interview with Dev Mandavia, CEO of Ethos Medical

Ethos Medical, a startup founded by Georgia Tech alumni, has developed the Iris needle guidance system to assist clinicians in successfully performing lumbar punctures. The system allows a clinician to visualize the needle traveling through tissue in real time. Tracking the needle path in this way is intended to improve the success rate and reduce (Read more...)

New Non-Toxic, Printable Biomedical Material Developed

Synthetic dry elastomers are polymeric materials that feature cross-linked networks that form into random and unordered shapes and textures. These materials have a host of properties that are applicable in biomedicine, but the randomness of their internal structures at different scales makes it difficult to actually use these elastomers. Now, resea (Read more...)

Masimo Receives FDA Approval for Continuous RRp Monitoring

Masimo announced that it received FDA clearance for continuous RRp (respiration rate from the photoplethysmograph) monitoring with its with Rad-97, Radical-7, and Radius-7 Pulse Co-Oximeters. Usually, monitoring respiration rate involves manually counting breaths with a timer or using chest straps that need to be fitted. The newly-approved Mas (Read more...)

nView Medical’s Fast 3D Intraoperative Imaging with Less Radiation: Interview with CEO Cristian Atria

Fluoroscopy is used in surgical procedures to visualize structures and tools in real-time, allowing surgeons to monitor the movement of a device, instrument, or body part. However, fluoroscopy is a 2D technology that can lead to surgical inaccuracies. Alternative 3D imaging systems provide higher accuracy, but they sometimes require pausing the sur (Read more...)

Artificial Self-Assembled Blood Vessels

A team of researchers headed by groups at University of Nottingham and Queen Mary University London have come up with a smart material that forms into new blood vessels. Made out of graphene oxide and a protein, the material is 3D printed and naturally forms into tubular shapes that are very similar to blood vessels. […]

New HydroPICC Prevents Clogged Central Line Catheters

Access Vascular, based in Bedford, Massachusetts, won FDA clearance for the latest version of its HydroPICC anti-thrombogenic central line catheter. As with the original, which was cleared two years ago, the new device features Access’s unique “bulk-hydrophilic” material that prevents clogging by being rich in water while carrying (Read more...)

FDA Clears First Pulse Oximeter to Measure Breathing Rate

Masimo just received the first FDA clearance for a fingertip pulse oximeter that can measure respiration rate. The MightySat Rx spot-check pulse oximeter includes a technology known as Respiration Rate from the Pleth (RRP) that makes it unnecessary to perform manual counts or use chest electrodes to measure respiration rate. The device can be used (Read more...)

Device Prints Scaffolds Inside Wounds to Replace Lost Tissue

3D printing of artificial scaffolds intended to replace injured tissues has become a ballyhooed technology that’s yet to prove itself in clinical practice. One issue that complicates things is that the scaffolds have to match the volume that they’ll be replacing, in both shape and the direction in which cells will have to grow. To [&hel (Read more...)

Scientists Make Organs Transparent

Whole organs are difficult to study in minute detail, as they have to be sliced into extremely thin sections to map out their interior. CT and magnetic resonance imaging help to an extent, but researchers at the Helmholtz Zentrum München, Ludwig Maximilians University Munich, and Technical University of Munich in Germany have managed to make [ (Read more...)

Artificial Tissue Patches to Heal Damaged Hearts

Post myocardial infarction (heart attack), damaged heart tissue doesn’t tend to heal very well. Not only is the pumping action weakened due to muscle cells dying, but the electrical signaling through the heart can also be impeded. Scientists at Trinity College Dublin have now developed remarkable new patches that mimic the electrical conducti (Read more...)

Electronic Bandage Delivers Drugs, Leaves No Scar

Chronic wounds, such as those associated with diabetes, can be incredibly difficult to manage. Even the process of accessing and medicating the wound can be detrimental to healing. Researchers from University of Nebraska-Lincoln, Harvard Medical School, and University of Connecticut are now reporting on having developed an electronic bandage that c (Read more...)

3D Printed Implants With Layers of Living Cells

3D printing replacement tissues and organs is still in the early stages of development, but it is clear that custom printed implants will have to integrate multiple types of cells in different locations in order to perform like native tissues. Researchers at Rice University have just unveiled a new method of 3D printing solid plastic […]

Microsure MUSA Robot Used for First Time on Real Patients

In a world first, clinicians at Maastricht University have used a robot to perform “supermicrosurgeries”, which involved operating on vessels as small as 0.3 mm in diameter. The procedures were conducted on women with lymphedema, a condition that arose as a result of breast cancer, whose lymphatic vessels were connected to veins to prov (Read more...)
