Abstract
Abstract An implant delivery system is disclosed. The delivery system includes an elongated member having an implant mounting location. A self-expandable implant is mounted at the implant mounting location. The implant is held in a compressed orientation by a retractable sheath. An interlock structure prevents the implant from deploying prematurely as the sheath is retracted. The interlock structure includes radio-opaque markers that identify the position of the implant.

Claim 1
Independent Claim
133 words
1 . A medical device comprising: an implant including a plurality of struts having terminal ends, at least some of the terminal ends of the struts including enlargements, the implant also including radiopaque markers positioned within at least some of the enlargements; and an implant delivery system including an inner member and an outer sheath that mounts over the inner member, the delivery system including an implant mounting location at which the implant mounts, the outer sheath being movable from a transport position where the sheath covers the implant at the implant mounting location, to a deploy position where the implant is exposed, the implant delivery system further including an interlock structure for preventing premature deployment of the implant, the interlock structure defining a receptacle for receiving at least one of the enlargements.
