Abstract:
This invention relates to the design and function of a device which allows for retrieval of a previously implanted valve prosthesis from a beating heart without extracorporeal circulation using a transcatheter retrieval system, including a guide component to facilitate the compression of the valve and retraction into a retrieval catheter, as well as an improved prosthetic transcatheter heart valve having one or more of: a series of radially extending tines having a loop terminus to improve sealing a deployed prosthetic mitral valve against hemodynamic leaking, a pre-compressible stent-in-stent design, or an articulating cuff attached to a covered stent-valve and a commissural sealing skirt structure attached to the underside of the articulating cuff.

Claim (Index 7):
A prosthetic mitral valve comprising:\n an outer cylindrical stent having an atrium end; a circumferentially continuous tissue collar for atrial sealing, supported by a first end of the outer cylindrical stent; an inner stent having a diameter smaller than a diameter of the outer cylindrical stent and being disposed in the outer cylindrical stent such that a gap is defined between the outer cylindrical stent and the inner stent, the tissue collar being coupled to a first end of the inner stent such that the tissue collar extends across the gap from the outer cylindrical stent to the inner stent to limit flow through the gap; and a leaflet apparatus disposed in the inner stent.
