Abstract
A stent delivery system can include a core member, an introducer sheath, and a microcatheter. The core member can have a distal segment. The stent engagement member can have a generally tubular body positioned about the core member distal segment and can be rotatably coupled to the core member. The engagement member can include an inner layer that has a first durometer and an outer layer that has a second durometer less than the first durometer. The stent can extend along the core member distal segment such that an inner surface of the stent is engaged by the engagement member outer layer for facilitating rotation of the stent relative to the core member.
