摘要

The purpose of the present invention is to provide a balloon catheter which is usable in intravenous chemical abrasion for treating primary aldosteronism and which enables, in particular, exclusive treatment of tumor in a branch diagnosed as abnormal. The balloon catheter according to the present invention, which is to be used in chemical abrasion for treating adrenal tumor via an intravenous approach, comprises an inner tube (10), an outer tube (30), a balloon (50) and a connector (70), said connector (70) comprising a guide wire port (71) and an inflation port (73), wherein: the outer tube (30) comprises a high-hardness part (301) on the proximal end side having a hardness of 72D or higher and a low-hardness part (302) on the distal end side having a hardness of 25D or higher and lower than 72D; the outer diameter of the outer tube (30) is 0.70-1.20 mm; and the length of the balloon (50) is 0.5-5 mm.
