Cryotherapy catheter for detecting and treating vulnerable plaque

摘要

Methods, apparatus, and kits detect and/or treat vulnerable plaque of a blood vessel. A temperature differential can o be sensed along a lumen surface with temperature sensors on a balloon filled with warm gas. Treatment methods include controlled and safe cryogenic cooling of vulnerable plaque to inhibit release of retained fluid within the vulnerable plaque so as to inhibit acute coronary syndrome and to help maintain patency of a body lumen.
