Implant delivery system and method

摘要

An implant delivery system may comprise a catheter including at least one lumen, a guide wire configured to be received in the lumen, and an implant. The guide wire may comprise a clamping mechanism disposed about a distal end of the guide wire. The clamping mechanism may include a first and at least a second jaw wherein at least one of the jaws is configured to pivot between a closed position wherein the jaws define at least one internal cavity between the jaws configured to receive at least a portion of the implant and an open position configured to release the implant. The implant may be configured to be received in the lumen and may comprise a driver configured to be releasably received in the cavity of the clamping mechanism.

1. An implant delivery system comprising:
a catheter including at least one lumen; a guide wire configured to be received in said lumen, said guide wire comprising a clamping mechanism disposed about a distal end, said clamping mechanism comprising a first jaw and a second jaw, said first and second jaws each comprising a proximal end and a distal end; and an implant configured to be received in said lumen, said implant comprising:
a shaft having a first end region and a second end region,a spacer disposed proximate to said second end region and configured to interact with at least a portion of at least one cusp of a heart valve to at least partially restrict a flow of blood through said heart valve in a closed position,at least one anchor coupled to said first end region of said shaft, said anchor configured to secure said implant to native coronary tissue, anda driver coupled to said second end region of said shaft generally opposite said first end region, wherein said driver is configured to be releasably received in said clamping mechanism of said guide wire; wherein a distal end of at least one of said first and second jaws comprises a first chamfered region that engages said driver to cam open said clamping mechanism.
