Abstract
Apparatus and methods are provided for use with a prosthetic valve that is designated for implantation at a patient'"'"'s native heart valve, including a valve ring having a plurality of ring segments, each of the segments being hingedly coupled to an adjacent segment at a pivot joint. The valve ring is placed adjacent to a surface of the native heart valve, the prosthetic valve having been coupled to the valve ring. In an expanded state thereof, the valve ring defines a ring, all of the pivot joints being disposed in a plane that is perpendicular to a longitudinal axis of the ring. The valve ring is foldable into a shape that has a generally circular cross-section that defines and surrounds at least in part a central lumen, by folding the segments with respect to each other, at the pivot joints. Other embodiments are also described.

18. Apparatus for implantation at a native valve of a patient, the apparatus having an upstream end and a downstream end and a longitudinal axis therebetween, and comprising:
-
a plurality of components, the plurality of components comprising an annular element; a plurality of prosthetic valve leaflets couplable to an inner perimeter of the annular element; and a plurality of anchors distributed circumferentially around the annular element, each anchor having; a first portion attached to the annular element, and a second portion that; extends from the first portion in a circumferential direction around the longitudinal axis of the apparatus, is configured to grasp chordae tendineae of the native valve, and is disposed further, in the circumferential direction, around the longitudinal axis of the apparatus than is any point of attachment of the anchor to the annular element, wherein at least one component of the plurality of components is disposed downstream from the second portion of the plurality of anchors. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27)

28. Apparatus for implantation at a native valve of a patient, the apparatus comprising a prosthetic valve having (i) a collapsed state for transluminal delivery to the valve, and (ii) an expanded state, and comprising:
-
an annular element; a plurality of prosthetic leaflets, couplable to an inner perimeter of the annular element; and a plurality of anchors distributed circumferentially around the annular element, each anchor; having a first end coupled to the annular element, and in the expanded state, extending from the first end radially away from the annular element and circumferentially alongside a respective portion of the annular element so as to define a space between the anchor and the annular element. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)
