An X-ray detectable pressure microsensor for monitoring coronary in-stent restenosis

We present a novel implantable X-ray-addressable MEMS Blood Pressure sensor, the X-BP, for the noninvasive and cost-effective surveillance of coronary in-stent restenosis. We successfully fabricated and tested the X-BP sensor and its pressure response curve. We placed the X-BP sensor in a coronary stent and prove adequate visibility in a clinically realistic scenario.
