Yeast Powered Radiation Detectors to Keep Clinicians Safe

Radiation dosimeters are commonly used by clinicians working around CT scanners, fluoroscopes, radiotherapy systems, and other equipment. Typically, after wearing one for a month or so, the detector is sent to the manufacturer and the results come about a week or two later, though real-time smart counters are coming out. All these counters are also (Read more...)

Nano-Optic Endoscope Allows High-Resolution Imaging

Researchers at Harvard University and Massachusetts General Hospital have developed a new type of endoscopic imaging catheter. The catheter uses metalenses, which contain nanostructures to focus light, to achieve higher resolution imaging than conventional catheter imaging systems. So far, the researchers have used the new system to image deep into (Read more...)

TEECAD Camera Gives Vision to TEE Probes

A young medtech company called Visura Technologies, based outside of Chicago, won FDA clearance for its TEE Camera Assist Device, TEECAD for short. The device is designed to be connected to a transesophageal echocardiography (TEE) ultrasound probe, letting the physician see the upper airway and esophagus while navigating the probe toward its d (Read more...)

The new family of microcatheters shows significant improvement over previous devices, and offers physicians enhanced performan (Read more...)

Smart Stent Monitors Blood Flow, Detects Restenosis

Vascular stents are some of the most commonly implanted medical devices, keeping millions of arteries open to uninterrupted blood flow. Though they tend to work well at first, too many end up being re-stenosed by new deposits of plaque and scar tissue often forms in the vicinity, blocking blood flow through the stent. Typically, renewed […]
