1. A stent delivery system, comprising:
- a core member having a distal segment; and
first and second restraints coupled to the core member distal segment and axially spaced apart from each other to provide an axial gap, the first and second restraints each having an outer profile that tapers radially inwardly;
a stent engagement component rotatably coupled to the core member between the first and second restraints.

Abstract
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.
