Heart valve prosthesis and separate support flange for attachment thereto
First Claim
1. A valve prosthesis assembly configured for transcatheter implantation into a native valve site, the valve prosthesis assembly comprising:
- a valve prosthesis having a compressed configuration for delivery within a vasculature and a radially expanded configuration for deployment within an annulus of the native valve site, the valve prosthesis including,a prosthetic valve component, anda frame includinga central portion supporting the prosthetic valve component, the central portion configured to fit within an annulus of the native valve site, andan inflow portion configured to engage an upstream side of the annulus and restrict movement of the valve prosthesis in a downstream direction of blood flow at the native valve site;
a separate support flange configured to be attached to the frame after the valve prosthesis has been deployed in situ, wherein the support flange is configured to be located upstream of the inflow portion of the frame; and
a plurality of anchors configured to attach the support flange to the frame and configured to embed into the annulus to anchor the frame of the valve prosthesis to the native valve.

Abstract
A valve prosthesis assembly for implantation into a native valve site includes a valve prosthesis with a prosthetic valve component and a frame. The frame of the valve prosthesis includes a central portion supporting the prosthetic valve component, the central portion being configured to fit within an annulus of the native valve site, and an inflow portion configured to engage an upstream side of the annulus and restrict movement of the valve prosthesis in a downstream direction of blood flow at the native valve site. The valve prosthesis assembly also includes a separate support flange configured to be attached to the frame after the valve prosthesis has been deployed in situ and a plurality of anchors configured to attach the support flange to the frame and configured to embed into the annulus to anchor the frame of the valve prosthesis to the native valve.

10. A valve prosthesis assembly configured for transcatheter implantation into a native valve site, the valve prosthesis assembly comprising:
-
a valve prosthesis having a compressed configuration for delivery within a vasculature and a radially expanded configuration for deployment within an annulus of the native valve site, the valve prosthesis including a prosthetic valve component, and a frame including a central portion supporting the prosthetic valve component, the central portion configured to fit within the annulus when the valve prosthesis is in the radially expanded configuration, and an inflow portion having a larger diameter than the central portion when the valve prosthesis is in the radially expanded configuration to engage an upstream side of the annulus and restrict movement of the valve prosthesis in a downstream direction of blood flow at the native valve site; a separate support flange configured to be attached to the frame after the valve prosthesis has been deployed in situ, the support flange having a compressed configuration for delivery within a vasculature and a radially expanded configuration for attachment to the frame, wherein the support flange in the radially expanded configuration is a ring defining an opening therethrough and wherein the support flange is formed from a shape memory material and wherein the support flange is configured to be located upstream of the inflow portion of the frame; and a plurality of anchors configured to attach the support flange to the frame and configured to embed into the annulus to anchor the frame of the valve prosthesis to the native valve. - View Dependent Claims (11, 12, 13, 14, 15)

16. A method of delivering and deploying a valve prosthesis assembly within a native valve via transcatheter implantation, the method comprising the steps of:
-
advancing a valve prosthesis within a vasculature to the native valve, wherein the valve prosthesis includes a prosthetic valve component coupled to a central portion of a frame and wherein the valve prosthesis is in a compressed configuration for delivery; deploying the valve prosthesis to a radially expanded configuration such that the central portion is disposed in the annulus of the native valve and an inflow portion having a larger diameter than the central portion engages an upstream side of the annulus to restrict movement of the valve prosthesis in a downstream direction of blood flow at the native valve; after the valve prosthesis has been deployed, delivering a support flange to the native valve; deploying the support flange upstream of the inflow portion of the frame; and attaching the support flange to the frame of the valve prosthesis with a plurality of anchors, wherein the anchors are configured to embed into the annulus in order to anchor the frame of the valve prosthesis to the native valve. - View Dependent Claims (17, 18, 19, 20)
