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.

Claims

1-18. -18. (canceled)

19. A medical device, comprising:

an implant including a plurality of struts having terminal ends, at least one of the terminal ends of the struts including first interlock structure, the first interlock structure having a radiopaque marker; and

an implant delivery system including an elongate member having second interlock structure, the second interlock structure coupling with the first interlock structure to prevent release of the implant while the first and second interlock structures are engaged.

20. The medical device according to claim 19 wherein the first interlock structure includes an enlargement and the second interlock structure includes a receptacle dimensioned to receive the enlargement.

21. The medical device according to claim 19 wherein a plurality of the terminal ends of the struts includes first interlock structure having the radiopaque marker.

22. The medical device according to claim 21 wherein the elongate member includes a plurality of the second interlock structures, the second interlock structures dimensioned to couple with respective first interlock structures of the implant.

23. A medical device, comprising:

an implant including a plurality of struts having terminal ends, a plurality of the struts including first interlock structure, at least some of the first interlock structures having a radiopaque marker; and

an implant delivery system including an elongate member defining a longitudinal axis and having a second interlock structure, the second interlock structure dimensioned to couple with the first interlock structures of radially adjacent terminal ends of the implant to prevent release of the implant while the first and second interlock structures are engaged.

24. The medical device according to claim 23 wherein the second interlock structure is a receptacle, the receptacle dimensioned to receive the first interlock structures of the radially adjacent terminal ends of the implant.

25. The medical device according to claim 24 wherein the first interlock structures of the radially adjacent terminal ends of the implant each define an enlargement.
