Abstract
The plaque resolving device is adapted to be inserted into and through the lumen of a blood vessel and manipulatable therethrough to a desired position where the device can be operated to soften atherosclerotic plaque buildup in, and to re-establish desired blood flow through, the blood vessel. The device includes an elongate tubular body having a proximal end, a distal end, and a tip member mounted to the distal end of the tubular body. An electrical heating element is mounted in the tip member for heating the tip member to a desired predetermined temperature. A temperature sensor is also mounted within the tip member. Energy supply and control circuitry is mounted at the proximal end of the tubular body and coupled to the electrical heating element and temperature sensor so that the heating element is maintained at a temperature within a predetermined temperature range relative the ambient temperature of the blood and plaque.
