Implant delivery system with interlock

An implant delivery system comprising:

• a catheter including an elongated member having an implant mounting location;
• an expandable implant mounted on the elongated member at the implant mounting location, the implant being expandable from a compressed orientation to an expanded orientation, the implant including first and second ends, and a male interlock structure;
• a sheath mounted on the elongated member, the sheath being positionable in a transport position in which the sheath covers the implant mounted at the implant mounting location, the sheath also being positionable in a deploy position in which the implant is exposed;
• a radio-opaque marker positioned adjacent the implant mounting location, the radio-opaque marker being made of a radio-opaque material and having a female interlock structure;
• wherein the male interlock structure of the implant interlocks with the female interlock structure of the radio-opaque marker to constrain axial movement of the implant relative to the elongated member when the implant is at least partially within the sheath.

A stent delivery system comprising:

• a catheter including an elongated body having a stent mounting location;
• an expandable stent mounted on the elongated body at the stent mounting location, the stent being expandable from a compressed orientation to an expanded orientation, the stent including first and second ends;
• a sheath mounted on the elongated body, the sheath being positionable in a transport position in which the sheath covers the stent mounted at the stent mounting location, the sheath also being positionable in a deploy position in which the stent is exposed;
• the stent including a plurality of struts at least some of which have free ends defining the first end of the stent, the free ends being adjacent cell defining regions of the stent, the cell defining regions defining cells having a cell length, the stent also including at least two male interlock structures positioned not more than one cell length away from the cells;
• and
• the elongated body including female interlock structures that receive the male interlock structures to constrain axial movement of the stent relative to the elongated body when the stent is at least partially within the sheath.
