  • Stent kit
    Patent number: 9844652
    Abstract: In a stent kit in which a stent tube has an arc-shaped part at one or both ends, an inner catheter includes an arc-shaped part fitting in, and conforming to, each arc-shaped part of the stent tube. Because of the conforming shapes, the stent tube is not deformed by the inner catheter even if the inner catheter remains within the stent tube over a long time. Consequently, the arcuate shape of the arc-shaped part or parts of the stent tube are reliably restored when the inner catheter is pulled out.

  • Stent delivery system
    Patent number: 8986364
    Abstract: A stent delivery system has a pusher catheter having an opening to which a filament is tied to the distal end thereof, and a stent having a catching hole. Because a knot is loosely fit in the catching hole from inside, with an inner catheter supporting the loose-fitting, inadvertent uncoupling of the stent and the pusher catheter can be prevented until the inner catheter is pulled out, and the two can be easily uncoupled by pulling out the inner catheter.
