Definitions

  • connection member can be easily attached to and detached from the indwelling device described above.
  • the distance from the opening to the connecting member is longer than the distance from the tip of the guide device to the connected member.
  • the guide device when the distance from the opening to the connecting member is longer than the distance from the tip of the guide device to the connected member, the guide device extends in the second direction when connecting the connecting member and the connected member. It can suppress contacting a cylinder part. Therefore, the connection member and the connected member can be connected more smoothly.
  • the body 14 With the stent graft 11 placed in the blood vessel, the body 14 is placed in the abdominal aorta 102, the ipsilateral leg 16 is placed from the aneurysm 100 to the right common iliac artery 108, and the contralateral leg 18 is placed from the inside of the aneurysm 100 to the left.
  • the common iliac artery 110 By being arranged over the common iliac artery 110, it exhibits a Y shape as a whole.
  • the flow passage 12 communicates in the axial direction with the inside of the body 14, the same side and the opposite legs 16 and 18, and realizes blood flow from the abdominal aorta 102 to the common iliac artery 106.
  • the guide device 36 is configured as a guiding catheter 37 (second catheter) through which the second guide wire 40 can be inserted.
  • a guide wire lumen 58 (second accommodating portion) for accommodating the second guide wire 40 is provided along the axial direction, and the guide wire lumen 58 is provided at the distal end of the guiding catheter 37.
  • a tip opening 58a is formed in communication with.
  • an X-ray contrast marker 60 is provided at the distal end of the guiding catheter 37, and the marker 60 is imaged under X-ray imaging, so that the distal end of the guiding catheter 37 in the living body can be visualized. The position can be confirmed.
  • the delivery system 10 is suitably used for a procedure (stent graft treatment) in which the first and second stent grafts 26 and 30 are delivered to the aneurysm 100 generated in the abdominal aorta 102 and both members are assembled in the aneurysm 100. Is done. Before the stent graft treatment is performed, X-ray imaging of the vicinity of the aneurysm 100 that is a lesioned part of the patient is performed, and the position and shape of the aneurysm 100 are specified. Further, priming for supplying a flushing liquid or the like into the first and second delivery devices 32 and 34 is performed.
  • the body 14 of the first stent graft 26 As the sheath 42 is further retracted, the body 14 of the first stent graft 26, a portion of the ipsilateral leg 16 and the connecting portion 24 of the contralateral leg 18 are exposed and expand within the aneurysm 100.
  • the first delivery device 32 exposes the first magnet 46 in the knob 100 as the same leg 16 is exposed. The backward movement of the sheath 42 is temporarily stopped at the timing when the first magnet 46 is exposed.
  • the first magnet 46 is disposed on the side of the opposite leg 18 of the same leg 16 and below the connecting portion 24. That is, the N-pole surface 46 b of the first magnet 46 is in a standby state facing the separation portion 28 inserted into the connecting portion 24.
