Abstract
Apparatus and methods are provided, including a plurality of anchoring elements, each of the anchoring elements being an elongate element that is curved to define an opening. A housing holds each of the anchoring elements. A mandrel is reversibly disposable through the openings defined by the anchoring elements. The anchoring elements are configured such that, in response to removal of the mandrel from the openings, ends of the anchoring elements automatically move outwardly, and diameters of the openings decrease, due to elastic loading of the anchoring elements. Other embodiments are also described.
Claims11
1-63. (canceled)
64:
- A method, comprising:
- coupling to a delivery catheter a heart valve apparatus comprising a compressible member, an elongated tether, and an anchoring element, the elongated tether comprising a proximal end and a distal end, the proximal end coupled to the compressible member, the distal end coupled to the anchoring element;
- delivering the heart valve apparatus across a septum of a heart and into a left atrium of the heart;
- deploying from the delivery catheter the compressible member at a mitral valve of the heart;
- deploying from the delivery catheter the anchoring element at a vicinity of an apex of the heart;
- and
- removing the delivery catheter from the heart.
4 more elements
65:
- The method of claim 64, wherein the septum of the heart is an inter-atrial septum of a heart.
66:
- The method of claim 64, wherein the compressible member comprises a ring.
67:
- The method of claim 64, wherein deploying the compressible member at a mitral valve of the heart comprises anchoring the compressible member to the mitral valve.
68:
- The method of claim 64, wherein delivering the heart valve apparatus into the left atrium occurs while the heart is beating.
69:
- The method of claim 64, wherein deploying the anchoring element at a vicinity of an apex of the heart comprises anchoring the anchor to myocardium of the heart.
70:
- The method of claim 64, wherein deploying the anchoring element at a vicinity of an apex of the heart comprises anchoring the anchor to a surface of the heart.
71:
- The method of claim 64, wherein the heart valve apparatus comprises a polymer.
72:
- The method of claim 64, wherein the heart valve apparatus comprises a metal.
73:
- The method of claim 72, wherein the metal is a shape-memory alloy.
