Patent

CA 2065261

A hot tip catheter assembly (3) is disclosed which resolves atherosclerotic plaque buildup in vivo. The catheter has a heater (12), a cap (14), thermocouple, power leads (22a, 22b), thermocouple leads (20), and a central distal lumen (17) to position the catheter within the artery. The catheter tip has a thin, non-adhesive coating (25) of a hard, heat-conducting material. The thermocouple is used to continuously evaluate the temperature at the tip of the catheter, and the temperature is then regulated by a computer controlled feedback system. The catheter can completely melt the buildup without damage to the artery by direct contact with the plaque, without use of balloon catheter angioplasty. Until further notice, any designation of "DE" in any international application whose international filing date is prior to October 3, 1990, shall have effect in the territory of the Federal Republic of Germany with the exception of the territory of the former German Democratic Republic.
