PROSTHETIC HEART VALVE FOR TRANSFEMORAL DELIVERY
First Claim
1. Apparatus comprising a valve prosthesis for attachment to a native valve complex of a subject, the prosthesis comprising:
- a support frame, which is shaped so as to define;
a plurality of axial support arches, which extend in a radially outward direction, and are configured to apply, regardless of a rotational orientation of the support frame with respect to the native valve complex, an upstream axial force to a downstream side of one or more native structures selected from the group consisting of;
native leaflet tips of the native valve complex, and native valve commissures, andan upstream skirt, which is configured to apply a downstream axial force on an upstream side of the native valve complex; and
a prosthetic heart valve, coupled to a portion of the support frame.

Abstract
Apparatus is provided that includes a valve prosthesis for attachment to a native valve complex of a subject. The prosthesis includes a support frame, which is shaped so as to define a plurality of axial support arches, which extend in a radially outward direction, and are configured to apply, regardless of a rotational orientation of the support frame with respect to the native valve complex, an upstream axial force to a downstream side of one or more native structures selected from the group consisting of: native leaflet tips of the native valve complex, and native valve commissures. The support frame is also shaped so as to define an upstream skirt, which is configured to apply a downstream axial force on an upstream side of the native valve complex. The prosthesis further includes a prosthetic heart valve, coupled to a portion of the support frame. Other embodiments are also described.

14. A method comprising:
-
providing a valve prosthesis, which includes (a) a support frame, which is shaped so as to define (i) a plurality of axial support arches, which extend in a radially outward direction, and (ii) an upstream skirt, and (b) a prosthetic heart valve, coupled to a portion of the support frame; and positioning the valve prosthesis at a native valve complex of a subject, such that; the axial support arches apply, regardless of a rotational orientation of the support frame with respect to the native valve complex, an upstream axial force to a downstream side of one or more native structures selected from the group consisting of;
native leaflet tips of the native valve complex, and native valve commissures, andthe upstream skirt applies a downstream axial force on an upstream side of the native valve complex. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
