BRITISH COLUMBIA RESEARCHERS PRODUCE FIRST ANGIOPLASTY-READY SMART STENT
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 patient symptoms are the first indication that restenosis is occurring. Being able to detect the rate of blood flowing through a stent can help identify whether something is amiss.
Researchers at University of British Columbia have developed a vascular stent that has a built-in sensor for measuring blood flow and a radio antenna to transmit the readings to an external device. The technology doesn’t require any changes in implantation procedures and should be applicable to be integrated into existing stents. The researchers describe the device as “the first angioplasty-ready smart stent
