Abstract:
1. A prosthesis deployment device comprising: a catheter body; a guide wire catheter extending from the catheter body to a nose cone dilator of a proximal end of the deployment device; a trigger wire guide extending partially between the catheter body and the nose cone dilator, the trigger wire guide configured to retain a proximal end of a prosthesis distally of the nose cone dilator, the trigger wire guide comprising: an enlarged proximal portion adjacent to the nose cone dilator: a tubular body portion adjacent to the enlarged proximal portion having an outer diameter less than the outer diameter of the enlarged proximal portion: a lumen disposed within the trigger wire guide and separate and apart from the guide wire catheter, the trigger wire guide being radially fixed relative to the guide wire catheter, the lumen extending at least partially along the trigger wire guide between the catheter body and the nose cone dilator; and an aperture in the lumen formed along the enlarged proximal portion of the trigger wire guide adjacent the nose cone dilator; a trigger wire release mechanism disposed at the distal end of the deployment device; and a trigger wire extending from the trigger wire release mechanism through the trigger wire guide, the trigger wire at least partially disposed within the lumen, and configured to exit the aperture to engage the prosthesis, a stent of the prosthesis, or a suture retaining the prosthesis to thereby retain the prosthesis.
