INTRODUCER FOR PROSTHETIC HEART VALVE
First Claim
1. A method of implanting a prosthetic heart valve comprising:
- making an incision in the vasculature of a patient'"'"'s body;
threading one or more sutures through a native annulus of the heart and extending the one or more sutures outwardly through the incision and through a portion of the prosthetic valve;
placing an introducer around the one or more sutures and inserting the introducer into and through the incision such that a distal end and a proximal end of the introducer are on opposite sides of the incision;
sliding the prosthetic valve along the one or more sutures and through the introducer until the prosthetic valve engages the annulus;
removing the introducer from the incision; and
securing the valve to the annulus with the one or more sutures.

Abstract
The present disclosure concerns embodiments of an introducer that is adapted to facilitate insertion of a prosthetic device, such as a prosthetic heart valve, into a patient'"'"'s vasculature. In one embodiment, the introducer comprises an elongated body defining a central lumen extending between distal and proximal ends of the body. The introducer body can also have a longitudinally extending gap extending along the length of the body between the distal end proximal ends. The gap in the introducer allows a user to place the introducer around implant sutures by passing the sutures through the gap and into the central lumen. Similarly, the gap allows the introducer to be easily removed from the sutures and/or a delivery device by passing them outwardly through the gap.
