Patent ID: 8114145

Claim:
A prosthesis deployment device comprising: a nose cone dilator located on a proximal end of the deployment device; an elongate catheter body coupled to the nose cone dilator, the elongate catheter body having a guide wire lumen extending therethrough; a trigger wire guide concentric about the elongate catheter body and extending along at least a portion of the elongate catheter body, the trigger wire guide comprising: an enlarged proximal portion adjacent to the nose cone dilator; a distal portion of increasing diameter transitioning to the enlarged proximal portion having a maximum outer diameter less than the outer diameter of the enlarged proximal portion; at least one trigger wire lumen formed within the trigger wire guide, the at least one trigger wire lumen separate and apart from the guide wire lumen; and an aperture in the least one trigger wire guide; and at least one trigger wire at least partially disposed within the at least one trigger wire lumen, the at least one trigger wire configured to exit the aperture to engage the prosthesis, a stent of the prosthesis, or a suture retaining the prosthesis, and enter the same aperture to thereby retain a portion of the prosthesis adjacent to the trigger wire guide.
