FFRangio Uses X-Rays to Measure Fractional Flow Reserve, Now Cleared in U.S.

Fractional flow reserve (FFR) is a measurement of the blood pressure before and after a narrowing of an artery. The larger the difference in the pressure across the stenosis, the more need there is to perform an interventional procedure to open up the artery. Normally, FFR is measured using a special intravascular catheter and this… Read More »

Glaucoma Drainage Device Uses Magnetic Fields for Self-Cleaning

Researchers at Purdue University have designed a prototype glaucoma drainage device that can clean itself under the influence of external magnetic waves. The innovation could lead to ocular drainage implants that last significantly longer than current models. The CDC has reported that approximately three million Americans are living with glaucoma. At present, clinicians prescribe medications,… Read More »
