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 26):
A prosthetic mitral valve comprising:\n an outer stent including a cylindrical first portion with a first end and a second end, and a second portion extending radially outwardly from the first end of the cylindrical first portion, the second portion configured to be at least partially disposed in an atrium of the heart; a tissue collar having a first portion supported by the second portion of the outer stent and a second portion supported by at least one of the first portion of the outer stent or the second portion of the outer stent, the first portion of the tissue collar having a length defined in a radial direction and the second portion of the tissue collar having a length defined in an axial direction, the length of the first portion of the tissue collar being greater than the length of the second portion of the tissue collar; an outer stent cover disposed on the first portion of the outer stent; an inner stent having a diameter smaller than a diameter of the first portion and a diameter of the second portion of the outer stent and being disposed in the first portion of the outer stent such that a gap is defined between the first portion of the outer stent and the inner; and a leaflet apparatus disposed in the inner stent.
