Title: MEASUREMENT AND ESTIMATION OF TEMPERATURES IN VESSELS
Abstract:
Identification, measurement, and/or estimation of temperatures of vessel walls and/or near-wall temperatures, including: cooling a first portion of vessel fluid flow; and measuring a temperature of a second portion of the flow, which second portion includes fluid cooled by the cooling, and which second portion is associated with a location at the wall. Identifying vulnerable plaque. Catheter temperature sensor, including an elongate body adapted for insertion into a blood vessel, a first temperature sensor at a first location along the catheter, a second temperature sensor at a location distanced at least 1 cm from the first location, and a mechanism for axially moving second sensor relative to the first sensor, along the catheter; and a system, for performing (blood) vessel wall temperature measurements. Heat treating a blood vessel wall (e.g., including [vulnerable] plaque) of a blood vessel.
