PROSTHETIC VALVE HAVING TAPERED TIP WHEN COMPRESSED FOR DELIVERY
First Claim
1. Apparatus comprising a valve prosthesis for attachment to a native valve complex of a subject, the prosthesis configured to assume a compressed delivery state and an uncompressed implantation state, the prosthesis comprising:
- a support frame, which is shaped so as to define an upstream inlet having upstream-most portions that are tapered in an upstream direction toward a central longitudinal axis of the prosthesis when the prosthesis assumes the compressed delivery state; and
a flexible prosthetic heart valve component, coupled to the support frame.

Abstract
Apparatus is provided that includes a valve prosthesis for attachment to a native valve complex of a subject. The prosthesis is configured to assume a compressed delivery state and an uncompressed implantation state. The prosthesis includes a support frame, which is shaped so as to define an upstream inlet having upstream-most portions that are tapered in an upstream direction toward a central longitudinal axis of the prosthesis when the prosthesis assumes the compressed delivery state. The prosthesis further includes a flexible prosthetic heart valve component, coupled to the support frame. Other embodiments are also described.

14. Apparatus comprising:
-
a delivery tube; and a valve prosthesis for attachment to a native valve complex of a subject, the prosthesis configured to assume a compressed delivery state when placed partially within the delivery tube, and to assume an uncompressed implantation state when removed from the delivery tube, the prosthesis comprising; a support frame, which extends partially outside of the delivery tube in an upstream direction when the prosthesis assumes the compressed delivery state; and a flexible prosthetic heart valve component, coupled to the support frame. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)

33. A method comprising:
-
providing a valve prosthesis for attachment to a native valve complex of a subject, the prosthesis configured to assume a compressed delivery state and an uncompressed implantation state, the prosthesis including (a) a support frame, which is shaped so as to define an upstream inlet, and (b) a flexible prosthetic heart valve component, coupled to the support frame; and causing the valve prosthesis to assume the compressed delivery state by inserting the valve prosthesis at least partially into a delivery tube, such that upstream-most portions of the upstream inlet taper in an upstream direction toward a central longitudinal axis of the prosthesis. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44)
