BALLOON FOR VASCULAR OCCLUSION BALLOON CATHETER, VASCULAR OCCLUSION BALLOON CATHETER, AND PRODUCTION METHOD FOR BALLOON FOR VASCULAR OCCLUSION BALLOON CATHETER

摘要

Provided is a balloon (10) for vascular occlusion that is made from a compound resin tube (9) having elasticity and thermoplasticity and that comprises: a bulge section (11) formed by plastic deformation; and a tip-side cylindrical section (12) and a rear end-side cylindrical section (13) that have a smaller diameter and a thicker wall than the bulge section (11). The bulge section (11) is extendable through elastic deformation brought about by the loading of internal pressure, and is shaped into a reduced-diameter form that comprises a wrinkle (71) in the axial direction. A balloon catheter (1) comprises a shaft section (2) and the balloon (10) which is fixed to the shaft section.
