PERCUTANEOUS MITRAL VALVE REPLACEMENT AND SEALING
First Claim
1. Apparatus for use at a native valve of a subject, the native valve including at least a first native leaflet and a second native leaflet, the apparatus comprising:
- an implant, comprising;
an annular portion, being configured to be placed against an upstream side of the native valve, and having an inner perimeter that defines an opening, andat least one leaflet clip;
coupled to the annular portion,comprising at least two clip arms and a clip-controller interface, the clip-controller interface being coupled to at least one of the clip arms, andconfigured to be coupled to a portion of the first native leaflet and a portion on the second native leaflet, and to hold to ether the portion of the first leaflet and the portion of the second leaflet; and
at least one clip controller, reversibly couplable to the clip-controller interface, and configured to facilitate opening and closing of the clip.

Abstract
For some applications, apparatus is provided for facilitating implantation of a prosthetic valve at a native heart valve of a subject, the apparatus comprising a prosthetic valve support, the prosthetic valve support (a) being configured to be transluminally-deliverable to the native valve and to be deployable at the native valve, and (b) comprising one or more tissue-engaging elements, configured to couple the prosthetic valve support to leaflets of the native valve without eliminating check valve functionality of the native valve. Other embodiments are also described.

16. Apparatus for use at a native heart valve of a subject, the native heart valve including a native annulus and a plurality of native leaflets that provide check valve functionality, the apparatus comprising an implant configured to be transluminally-delivered to the native valve and to be deployed at the native valve, the implant comprising:
-
one or more tissue-engaging elements, configured to be coupled to the native leaflets, and to couple the implant to the native leaflets without eliminating the check valve functionality, by holding together a portion of one of the native leaflets and a portion or another of the native leaflets such that the one leaflet, and the other leaflet become arranged to define two orifices between the one leaflet and the other leaflet, each orifice configured to function as a respective check-valve; and an annular portion, configured to be secured against an upstream side of the native valve by the coupling of the one or more tissue-engaging elements to the native leaflets. - View Dependent Claims (18, 24, 25, 32, 33, 34)

41. A method, comprising:
-
transluminally advancing an implant to a native heart valve of a subject; placing an annular portion of the implant against an upstream surface of the native heart valve, the implant including at least one clip coupled to the annular portion; and securing the annular portion against the upstream surface by coupling the at least one clip to at least one native leaflet of the native heart valve by using a clip controller to close arms of the clip around the at least one native leaflet. - View Dependent Claims (42)

43. A method, comprising:
-
transluminally advancing an implant to a native heart valve of a subject, the native heart valve having a first leaflet and a second leaflet, and the implant including at least one clip, and an annular portion coupled to the at least one clip; placing the annular portion of the implant against an upstream surface of the native heart valve; and arranging the first and second leaflets to define two orifices that each function as a respective check-valve, by coupling the at least one clip of the implant to the to the first and second leaflets, such that the at least one clip holds together a portion of the first leaflet and a portion of the second leaflet. - View Dependent Claims (44)
