LUMINAL STENTING

摘要

A stent delivery system can include a core member, first and second restraints, and a stent engagement component. The core member can have a distal segment. The first and second restraints can be coupled to the core member distal segment and axially spaced apart from each other to provide an axial gap. The first and second restraints can each have an outer profile that tapers radially inwardly in directions away from the gap. The stent engagement component can be at least partially disposed in the axial gap between the first and second restraints such that the component is slidably and rotatably coupled to the core member distal segment.

主权项

1. A method of delivering a stent delivery system, the method comprising:
inserting the delivery system into a curved path, the delivery system comprising a catheter, a core member disposed within the catheter, first and second restraints coupled to the core member, a stent engagement component coupled to the core member between the first and second restraints, and a stent extending over at least one of the first or second restraints, the first and second restraints each having a longitudinally tapered end; and causing the core member to bend in the curved path, more than the core member could if the first and second restraints were not tapered, without causing the first and second restraints to compress the stent against an inner wall of the catheter.
