1. A stent delivery system, comprising:
- a core member having a distal segment;
a stent engagement member positioned along the core member distal segment and coupled to the core member, the engagement member comprising an outer surface; and
a stent extending along the core member distal segment such that the outer surface of the engagement member engages an inner surface of the stent along at least a portion of only a distal half of the stent for transmitting an axial force from the core member to only the stent distal half.

Abstract
A stent delivery system can include a core member, a stent, and a stent engagement member. The engagement member can be positioned along a distal segment of the core member and be coupled to the core member. The engagement member can have an outer surface. The stent can extending along the core member distal segment such that the outer surface of the engagement member engages an inner surface of the stent along at least a portion of only a distal half of the stent for transmitting an axial force from the core member to only the stent distal half of the stent.

10. A stent delivery system, comprising:
-
a catheter having a lumen and an inner surface extending along the lumen; a core member, extending within the catheter lumen, having a distal segment and a device interface; and a stent extending along the core member distal segment, at least a portion of only a distal half of the stent being radially compressed between the interface and the catheter inner surface such that a distal axial force exerted on the core member is transmitted through the interface to pull the stent in a distal direction. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
