Abstract
The present invention provides methods, apparatus, and kits for detection and/or treatment of vulnerable plaque of a blood vessel having a lumen surface. Detection methods include sensing a temperature differential along a lumen surface with temperature sensors that thermally couple the lumen surface. 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. Treatment methods may include additional treatments, such as primary treatments or passivation.
