Definitions

  • the present invention relates to balloon catheters.
  • the opening of the hollow shaft will be occluded by the balloon when the balloon is deflated.
  • Such closure of the opening can occur, for example, when the hollow shaft at the portion corresponding to the balloon is pressed against the wall of the blood vessel, and the balloon positioned directly above the opening is strongly pressed against the outer peripheral surface of the hollow shaft.
  • the opening may be blocked by the balloon, and the dilating fluid may not be discharged sufficiently.
  • the balloon may not deflate as intended, which may hinder smooth withdrawal of the balloon catheter.
  • the groove portion 131 of this embodiment extends along a direction that is inclined with respect to the longitudinal direction of the hollow shaft 13 .
  • the groove 131 extends spirally in two opposite directions starting from the opening 13a1, and the angle between both ends of the groove 131 and the central axis of the hollow shaft 13 is 360°. A configuration is illustrated.
