Research Abstract

We have invented new stent retrieval device, and experienced stent retrieve using swine coronary artery. We have added some improvement to prototype device for three years, thisstent retrieval device could reach swine coronary artery to take deployed-stent out of coronary artery. But some technical problem have been remained.
