Beschreibung
Zusammenfassung:	A balloon catheter (15) includes a balloon (25), a catheter shaft (28), a heating unit (39), and an electrode temperature sensor (45). The catheter shaft (28) has an outer cylinder shaft (30) connected to the proximal end (25a) of the balloon (25), and an inner cylinder shaft (35) extending into the balloon (25) to be connected to the distal end (25a) of the balloon (25). The inner cylinder shaft (35) passes inside the outer cylinder shaft (30). The gap between the inner cylinder shaft (35) and the outer cylinder shaft (30) defines a liquid flow path (LP) leading to the inner space of the balloon (25). The heating unit (39) includes multiple heating electrodes (40). The multiple heating electrodes (40) are distributed over the outer circumferential surface of the inner cylinder shaft (35) in the balloon (25). The electrode temperature sensor (40) is provided in the balloon (25) to acquire information on the temperature of the heating electrodes (40).
