Ischemia detection system

摘要

The present invention provides devices and methods for detection of ischemic biological tissue by temporarily altering the temperature of the tissue and then monitoring the thermal profile of the tissue as it returns to normal temperature. Tissue areas of slower response time correspond to areas of reduced blood flow (ischemia). Several embodiments are disclosed. In one embodiment a fiber optic device is used to record thermal images of the tissue after it has been cooled by introduction of a cool fluid. In another embodiment detection is accomplished through the use of thermal sensors to monitor the temperature profile of the tissue after the temperature change.
