WIPO Patent Application WO/2014/122757
Kind Code:
A1
Abstract:
A balloon catheter (1) is provided with an inner tube (3), an outer tube (2), and a balloon (4) having the tip section (42) thereof fixed to the inner tube (3) and the rear edge section (44) thereof fixed to the outer tube (2). The balloon is provided with an expandable section (41) and a non-expandable cylindrical section (43) that is positioned between the expandable section and the rear edge section (44) and that extends to a predetermined length. In the balloon catheter (1), the three-point bending load value (A1) per unit flexure in the central part of the expandable section of the balloon and the three-point bending load value (A2) per unit flexure in the fixed section of the rear edge section of the cylindrical section of the balloon and the tip section of the outer tube satisfy A1 < A2. In addition, the difference between the three-point bending load value (A1) and the three-point bending load value (A2) is equal to or less than 50 mN/mm and the three-point bending load value (A1) is equal to or less than 50 mN/mm.
