TECHNIQUES FOR PERCUTANEOUS MITRAL VALVE REPLACEMENT AND SEALING
First Claim
1. Apparatus for use with a prosthetic valve for implantation at a native valve of a heart of a subject, the apparatus comprising an upstream support portion, the upstream support portion:
- (a) having a compressed configuration in which the support is transcatheterally deliverable to the native valve and in which the upstream support portion has a generally cylindrical shape, the cylindrical shape having a downstream end and an upstream end, each end having a perimeter, each perimeter of the cylindrical shape having a length,(b) having an uncompressed configuration in which the upstream support portion;
is configured to be placed against an upstream side of the native valve,is shaped to define an opening,has an outer perimeter and an inner perimeter, and(c) being movable from the compressed configuration to the uncompressed configuration,the apparatus being configured such that, when the upstream support portion moves from the compressed configuration to the uncompressed configuration thereof;
the perimeter of the downstream end of the upstream support portion in the compressed configuration thereof becomes the inner perimeter of the upstream support portion in the uncompressed configuration thereof, andthe perimeter of the upstream end of the upstream support portion in the compressed configuration thereof becomes the outer perimeter of the upstream support portion in the uncompressed configuration thereof.

Abstract
Apparatus is described for use with a native heart valve of a subject, the apparatus including (1) a prosthetic valve support, comprising an upstream support portion, the upstream support portion having (a) a compressed configuration and an uncompressed configuration in which the upstream support portion has an inner perimeter that defines an opening; and (2) a prosthetic valve, advanceable into the opening defined by the upstream support portion, and intracorporeally couplable to the upstream support portion by being expanded within the opening defined by the upstream support portion, the apparatus being configured such that, when the prosthetic valve is expanded within the opening defined by the upstream support portion, the expansion of the prosthetic valve is restricted by the inner perimeter of the upstream support portion, without causing the prosthetic valve support to apply a radially-expansive force to the native annulus. Other embodiments are also described.

34. Apparatus for use with a native heart valve of a subject, the native heart valve having a native annulus, the apparatus comprising:
-
a prosthetic valve support, comprising an upstream support portion, the upstream support portion having; a compressed configuration in which the upstream support portion is generally cylindrical, and is transcatheterally deliverable to the native valve, and an uncompressed configuration in which the upstream support portion; is configured to be placed against an upstream side of the native heart valve, and has an inner perimeter that defines an opening; and a prosthetic valve; having a compressed configuration in which the prosthetic valve is transcatheterally deliverable to the native valve, and advanceable into the opening defined by the upstream support portion, and being intracorporeally couplable to the upstream support portion by being expanded, the apparatus being configured such that, when the prosthetic valve is expanded, the expansion of the prosthetic valve is restricted by the prosthetic valve support, without causing the prosthetic valve support to apply a radially-expansive force to the native annulus. - View Dependent Claims (35, 42, 43, 44, 55)

68. A method for use with a prosthetic valve for implantation at a native valve of a heart of a subject, the method comprising:
-
delivering an upstream support portion of a prosthetic valve support, in a compressed configuration thereof, to an upstream side of the native valve, the upstream support portion in the compressed configuration thereof, having a generally cylindrical shape, the cylindrical shape having a downstream end and an upstream end, each end having a perimeter, each perimeter of the cylindrical shape having a length; coupling the prosthetic valve support to the native valve; and expanding the upstream support portion toward an uncompressed configuration thereof, such that; the perimeter of the downstream end of the upstream support portion in the compressed configuration thereof becomes an inner perimeter of the upstream support portion in the uncompressed configuration thereof, the perimeter of the upstream end of the upstream support portion in the compressed configuration thereof becomes an outer perimeter of the upstream support portion in the uncompressed configuration thereof, and the inner perimeter of the upstream support portion defines an opening. - View Dependent Claims (69, 70, 71, 80, 82, 87)
