First Claim
Patent Images
1. 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;
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.

Abstract
A prosthesis deployment device having a elongate catheter body and a trigger wire guide concentric about the elongate catheter body where the trigger wire guide comprises three trigger wire lumens separate and apart from a guide wire lumen, with three trigger wires being at least partially disposed in the three trigger wire lumens and configured to engage a portion of a prosthesis to retain the prosthesis adjacent to the trigger wire guide.

17. 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 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; and three trigger wire lumens formed within the trigger wire guide, each trigger wire lumen being separate from the guide wire lumen and extending at least partially within the trigger wire guide; and three trigger wires extending through the trigger wire guide, one trigger wire being at least partially disposed within each lumen and configured to exit each 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. - View Dependent Claims (18, 19, 20)
