  • Publication number: 20260108371
    Abstract: A stent delivery system includes a core member and a coupling assembly rotatably coupled to the core member distal segment. The coupling assembly includes first and second plates and first and second spacers. The first plate is rotatably coupled to the core member and includes an outer surface having three or more projections separated by recesses. The first spacer is coupled to the core member and disposed between the first plate and a proximal restraint. The second plate is rotatably coupled to the core member and includes an outer surface having three or more projections separated by recesses. The second spacer is coupled to the core member and disposed between the first plate and the second plate. A stent extends along the core member distal segment such that an inner surface of the stent is engaged by one or more projections of the first plate or the second plate.

  • Patent number: 11833069
    Abstract: A stent coupler for use with a medical device delivery system is disclosed. A stent delivery system includes a core member having a distal segment and a coupler positioned about the core member distal segment. The coupler is rotatably coupled to the core member and includes a rigid plate having a first end surface, a second end surface, and a side surface extending between the first and second end surfaces, the side surface comprising one or more projections separated by recesses. The delivery system further includes a stent extending along the core member distal segment such that an inner surface of the stent is engaged by the one or more projections of the engagement member.

  • Patent number: 10265207
    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.
