Implant for heart valve
CAFCFirst 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;
(i) coupled to the annular portion,(ii) comprising;
at least two clip arms, movable with respect to each other to open and close the clip; and
a clip-controller interface, the clip-controller interface being coupled to at least one of the clip arms, and(iii) configured;
to be coupled to a portion of the first native leaflet by the clip arms being brought together to close around the first native leaflet,to be coupled to a portion of the second native leaflet by the clip arms being brought together to close around the second native leaflet, andto hold together the portion of the first leaflet and the portion of the second leaflet; and
a delivery apparatus, configured to deliver the implant to the native valve, and comprising at least one clip controller, the at least one clip controller being reversibly couplable to the clip-controller interface, and configured to facilitate opening and closing of the clip, and the delivery apparatus being intracorporeally decouplable from the implant.

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.

9. 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 of 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 (10, 11, 12, 13, 14, 15)

16. A method, comprising:
-
using a delivery apparatus, transluminally advancing an implant to a native heart valve of a subject, the native valve including at least a first native leaflet and a second native leaflet, the implant including; 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, and at least one leaflet clip; (i) coupled to the annular portion, (ii) comprising; at least two clip arms, movable with respect to each other to open and close the clip; and a clip-controller interface, the clip-controller interface being coupled to at least one of the clip arms, and (iii) configured; to be coupled to a portion of the first native leaflet by the clip arms being brought together to close around the first native leaflet, to be coupled to a portion of the second native leaflet by the clip arms being brought together to close around the second native leaflet, and to hold together the portion of the first leaflet and the portion of the second leaflet; and placing the annular portion of the implant against the upstream surface of the native heart valve; using a clip controller of the delivery apparatus, securing the annular portion against the upstream surface by coupling the at least one leaflet clip to the portion of the first native leaflet and to the portion of the second native leaflet such that the at least one leaflet clip holds together the portion of the first native leaflet and the portion of the second native leaflet, the clip controller being reversibly couplable to the clip-controller interface, and configured to facilitate opening and closing of the clip; and subsequently, intracorporeally decoupling the delivery apparatus from the implant. - View Dependent Claims (17)
