Prosthetic valve
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 ends that are tapered in an upstream direction toward a central longitudinal axis of the prosthesis when the prosthesis assumes the compressed delivery state, wherein the upstream-most ends of the inlet converge to within 2 mm of the central longitudinal axis when the prosthesis assumes the compressed delivery state; and
a flexible prosthetic heart valve component, coupled to the support frame.

Abstract
In some embodiments, an apparatus 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, and a flexible prosthetic heart valve component, coupled to the support frame. Other embodiments are also described.

13. 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 ends that are tapered in an upstream direction toward a central longitudinal axis of the prosthesis when the prosthesis assumes the compressed delivery state; a flexible prosthetic heart valve component, coupled to the support frame; and a delivery tube, wherein the prosthesis is configured to assume the compressed delivery state upon placement of the valve prosthesis partially within the delivery tube, and wherein when the prosthesis assumes the compressed delivery state, a portion of the upstream inlet that extends outside of the delivery tube has a greatest outer inlet diameter that is greater than an outer tube diameter of the delivery tube. - View Dependent Claims (15, 17)
