Clever catheter lets surgeons see inside arteries to trim plaque

The Pantheris catheter developed by Avinger takes the physician out of the radiation field. A clever catheter design lets cardiologists see inside arteries and precisely remove plaque from diseased tissue. The Pantheris catheter is safer than conventional radiation-guided procedures because it takes the surgeon out of the radiation field, and along with on-board optics, it

This fly’s hearing could inspire better hearing aids

A small, yellow parasitic fly called the Ormia ochracea has a sense of directional hearing that is unsurpassed to any other creature in the animal kingdom, according to new University of Toronto Scarborough research. That spectacular hearing could one day be a model for new hearing aids. “These flies have highly specialized ears that provide

This microhole chip identifies and sorts cancer cells

Fraunhofer researchers have created a microhole chip that can identify and characterize cancer cells within minutes – helping to catch metastasis before it can begin. Traditional fluorescence-activated cell sorting (FACS) gives an estimate of the number of tumor cells in a patient’s bloodstream. If there is a higher concentration of tumor cells, there is a

This wearable patch detects sleep apnea

A disposable diagnostic patch can detect all types of sleep apnea, according to new clinical trial results. The results showed that the SomnaPatch device had a clinical agreement between the patch and standard polysomnography of 87.4%, with 95% confidence interval of 81.4% to 91.9%, according to its maker Somnarus. SomnaPatch weighs less than 1 ounce

FDA extends UDI compliance date for low risk devices

Labelers of class I and unclassified devices recently got a reprieve when FDA announced an extension of the compliance date for unique device identification (UDI). Makers of devices such as manual surgical instruments and mechanical wheelchairs will have 2 extra years to get these devices submitted to the Global unique device identification database (GUDID), FDA announced last

6 brain-controlled devices helping people regain movement

People who have lost feeling in their limbs or have lost the ability to move them may soon have those sensations restored thanks to a slew of recent brain-controlled device innovations. While we are moving toward less invasive methods such as electrode-filled caps on the head, there are still more invasive implants that are benefiting

Abbott heart device shown safe for infants

Developing very small devices that can be used for children is a significant challenge in the market. FDA is cautious to approve new devices into this market for vulnerable patients. But the efforts are needed to improve the health of babies, particularly those born with heart defects. Abbott’s reduced sized Amplatzer duct occluder II (ADO

RxFunction device helps diabetics walk again

Patients who have peripheral neuropathy as a result of diabetes have shown improvement in their gait and balance using RxFunction’s new wearable sensory prosthesis, according to a new study. A research study from Wingate University has tested the long-term benefits of using wearable technology company RxFunction’s Walkasins in people who have peripheral neuropathy. “These exciting

This nanofiber device can hear cells moving

A new miniature nanofiber device created by engineers at the University of California at San Diego is sensitive enough that it can feel bacteria swimming and can hear heart muscle cells beating. The device is 100 times thinner than a human hair and is made of optical fiber. It is designed to be able to detect forces

Artificial pancreas: These companies are racing to make one

Medical device companies are close to achieving the holy grail of diabetes treatment: a combined glucose sensor, control algorithm and insulin infusion device that effectively acts as an “artificial pancreas.” We explain more in our newest Medical Design & Outsourcing video. (And for a deeper dive, check out our recent roundup of companies in the

This could be the battery-free solution for pacemakers

A new energy storage system charges itself using ions from inside the human body – providing an exciting alternative to traditional batteries used in pacemakers, according to researchers at the University of California at Los Angeles and the University of Connecticut. Researchers at the universities developed a bio-friendly energy storage system called a biological supercapacitor;
