Abstract
Apparatus is provided for use with a native valve of a heart of a subject, the apparatus including (1) an annular upstream support portion, configured to be transluminally placed against an atrial surface of the native valve; (2) a tissue-engaging element that includes a coupling portion configured to be transluminally coupled to tissue in a ventricle of the heart; (3) an elastically-stretchable holding element, configured to secure the upstream support portion against the atrial surface by elastically coupling the coupling portion to the upstream support portion; and (4) a prosthetic valve, configured to be transluminally delivered to the native valve and intracorporeally coupled to the upstream support portion subsequently to the securing of the upstream support portion against the atrial surface. Other embodiments are also described.

36. A method, comprising:
-
securing an annular upstream support portion against an atrial surface of a native valve of a heart of a subject by; transluminally placing the upstream support portion against the atrial surface of the native valve of the heart, and anchoring a coupling portion of a tissue-engaging element to tissue in a ventricle of the heart, the tissue-engaging element being elastically couplable to the upstream support portion via an elastically-stretchable holding element; transluminally delivering a prosthetic valve to the native valve; and intracorporeally coupling the prosthetic valve to the upstream support portion subsequently to the securing of the upstream support portion against the atrial surface. - View Dependent Claims (37, 38, 39, 40)

41. Apparatus for use at a heart of a subject, the apparatus comprising:
-
a self-expanding prosthetic valve having a compressed state in which the prosthetic valve is transluminally advanceable, and an expanded state; and a delivery tube; comprising a flexible material, and configured to house the prosthetic valve in a manner in which the tube (1) retains the prosthetic valve in the compressed state, and (2) conforms to a shape of the prosthetic valve in the compressed state. - View Dependent Claims (42, 43, 44, 45, 46, 47)
