Sutureless prosthetic heart valve
First Claim
1. A method of implanting a prosthetic heart valve in a patient, the prosthetic heart valve including a first valve anchoring feature spaced apart from a second valve anchoring feature, and having an expanded condition and a collapsed condition, the method comprising:
- making an incision in an aorta of the patient;
inserting the prosthetic heart valve into the patient'"'"'s cardiovascular system through the incision in the aorta while the prosthetic heart valve is coupled to a valve holder and while the prosthetic heart valve is in the expanded condition;
advancing the prosthetic heart valve to a position adjacent a native valve annulus in the patient so that the first valve anchoring feature is disposed on a first side of the native valve annulus and the second valve anchoring feature is disposed on a second side of the native valve annulus opposite the first side;
releasing the prosthetic heart valve from the valve holder;
removing the valve holder from the patient; and
closing the incision after removing the valve holder from the patient,wherein, after the incision is closed, the prosthetic heart valve does not contact the closed incision.

Abstract
A prosthetic heart valve for replacing a native valve includes a stent extending between an inflow end and an outflow end, and a valve assembly disposed within the stent. The prosthetic heart valve may include a supra-annular feature configured to anchor and seal the prosthetic valve above the native valve annulus and a sub-annular feature configured to anchor and seal the prosthetic valve below the native valve annulus. Each of the sub-annular feature and the supra-annular feature may be a sealing ring or a strut that extends radially outward from the stent. The prosthetic heart valve may be implanted in the patient via a sutureless approach and provide anchoring in a variety of patient populations, including those with resected native valve leaflets.
