ABSTRACT:
The method and apparatus of the present invention is for treating a blood vessel stenosis region in a subject. The method comprises the steps of inserting a catheter into a subject until a balloon located at a distal end portion of the catheter is within a treatment region of a blood vessel. The catheter comprises an elongated tubular body member having first and second axially extending passages. The balloon is located at a distal end portion of the tubular body member and is in fluid communication with the first and second passages. A mechanism supplies fluid under pressure through the first passage to a first axial end portion of the balloon to inflate the balloon. A heater located within the balloon elevates the temperature of the fluid to a first temperature. The first temperature is maintained for a predetermined time interal. A thermocouple senses the temperature of the fluid within the balloon. A control establishes the temperature during a thermal treatment cycle in response to the temperature of the fluid sensed by the thermocouple. The second passage conducts the heated fluid from the balloon at a second axially opposite end portion of the balloon after the thermal treatment cycle. The heated fluid removed from the balloon is replaced with a fluid at a second temperature less than the first temperature through the first passage.
