16. Apparatus for use at a native valve of a heart of a subject, the native valve including one or more leaflets, the apparatus comprising:
-
an upstream support portion; having a delivery state in which the upstream support portion is dimensioned to be transluminally advanced to the heart, and having an expanded state in which the upstream support portion is annular and configured to be disposed against an annulus of the native valve; at least two connectors; at least two clips, each of the clips; coupled to the upstream support portion via a respective one of the connectors, comprising at least two clip arms and a clip-controller interface coupled to at least one of the clip arms, and configured to be coupled to one of the leaflets by clamping the leaflet between the clip arms; and a clip controller, reversibly couplable to the clip-controller interface of at least one of the clips, and configured to facilitate opening and closing of the at least one of the clips, wherein the apparatus is configured such that the coupling of the clips to the leaflets secures the upstream support portion against an upstream side of the native valve. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
