Balloon catheter

Abstract

Provided is a balloon catheter capable of accurately applying pressure to an area of interest.　A balloon catheter (1) comprises: a shaft (10) extending in the longitudinal direction from the proximal side to the distal side; a first balloon (21) disposed on a distal portion of the shaft (10); and a balloon group (30) including a plurality of second balloons (22) provided on the outside of the first balloon (21) and arranged in the circumferential direction of the first balloon (21). In an expanded state of the first balloon (21) and the balloon group (30), a length (L1) from a distal end (21d) of the first balloon (21) to a proximal end (21p) of the first balloon (21) in the longitudinal direction is shorter than a length (L2) from a distal end (22d) of each second balloon (22) to a proximal end (22p) of the second balloon (22) in the longitudinal direction.
