Valve prosthesis configured for deployment in annular spacer
First Claim
1. A prosthetic heart valve, comprising:
- an annular spacer configured for deployment within a native heart valve, the annular spacer comprising;
a cylindrical skirt having an upstream end and a downstream end opposite from the upstream end, wherein a spacer opening extends through the cylindrical skirt between the upstream and downstream ends, anda disc-shaped wall arranged about the upstream end of the cylindrical skirt, the disc-shaped wall being configured to obstruct blood flow, wherein the disc-shaped wall comprises;
a support stent having a plurality of struts, andat least one opening configured to slide along a delivery mechanism, wherein a first portion of the support stent situated around the at least one opening has a different strut arrangement than a second portion of the support stent; and
a central valve section having a central lumen configured to support a valve prosthesis therein, wherein the central valve section is configured for disposal within the spacer opening of the annular spacer and includes at least one anchoring protrusion configured to extend radially outward from a downstream end of the central valve section,wherein the central valve section is configured for deployment into the heart separately from the annular spacer, andwherein the at least one anchoring protrusion of the central valve section is configured to extend through the downstream end of the spacer opening to prevent the central valve section from moving axially relative to the annular spacer.

Abstract
Embodiments of the present disclosure are directed to prosthetic heart valves and methods of use thereof. In one implementation, a prosthetic heart valve may include an annular spacer having a spacer opening therein and a disc-shaped wall configured to obstruct blood flow. The annular spacer may be configured for engaging with a native heart valve opening, such as the orifice of a mitral valve. The spacer opening may be sized to be smaller than the native heart valve opening. The prosthetic heart valve may also include a central valve section configured for disposal within the spacer opening. The central valve section may be separate from the annular spacer and may include one or more prosthetic valve leaflets.
