Abstract
A prosthetic mitral valve with improved blood flow to the left ventricular outflow tract. The prosthetic mitral valve includes an expandable outer stent having an atrial end and a ventricular end, and an expandable inner stent attached to and at least partially positioned within the outer stent. The inner stent has an inflow end, an outflow end and a tether connector securing a tether. A valve assembly including a cuff and a plurality of leaflets may be disposed within the inner stent. The tether connector is positioned at the inflow end of the inner stent so as to shorten the overall length of the prosthetic valve.
Claims20
A prosthetic heart valve, comprising:
- an expandable stent having an inflow end and an outflow end;
- a valve assembly disposed within the stent, the valve assembly including a cuff and a plurality of leaflets;
- a tether connector positioned between the inflow end and the valve assembly;
- and
- a tether secured to the tether connector.
A method of implanting a prosthetic heart valve, comprising:
- delivering a delivery device to a target site adjacent to a native valve annulus, the delivery device holding a prosthetic heart valve including a stent, a valve assembly disposed within the stent and a tether attached to the stent;
- deploying the prosthetic heart valve from the delivery device within the native valve annulus;
- creating a passage through the wall of the heart;
- extending the tether through the valve assembly and through the passage to a location outside the heart;
- tensioning the tether;
- and
- securing the tether to the wall of the heart.
