Balloon catheter and balloon catheter system

Abstract

A balloon catheter includes a balloon, a catheter shaft, a heating unit, and an electrode temperature sensor. The catheter shaft has an outer cylinder shaft connected to the proximal end of the balloon, and an inner cylinder shaft extending into the balloon to be connected to the distal end of the balloon. The inner cylinder shaft passes inside the outer cylinder shaft. The gap between the inner cylinder shaft and the outer cylinder shaft defines a liquid flow path leading to the inner space of the balloon. The heating unit includes multiple heating electrodes. The multiple heating electrodes are distributed over the outer circumferential surface of the inner cylinder shaft in the balloon. The electrode temperature sensor is provided in the balloon to acquire information on the temperature of the heating electrodes.
