Abstract:
1. A prosthetic treatment apparatus for treating a native mitral valve having a native annulus and native leaflets, comprising: a support having a downstream end configured to be positioned toward a left ventricle, an upstream end configured to be positioned toward a left atrium, and an interior, wherein the support is expandable from a low-profile configuration for implantation to an expanded configuration at a native mitral valve; a prosthetic valve having a tri-leaflet assembly mounted to the interior of the expandable support and adapted to allow blood flow in the downstream direction and to block blood flow in the upstream direction; a plurality of elongated members extending from a downstream portion of the support to which the prosthetic valve is attached and extending outwardly from the support in an upstream direction, wherein a skirt coupled to a downstream portion of the support and flaring outward in an upstream direction such that an upstream end of the flared portion is spaced outwardly from the support, wherein the skirt extends around the entire circumference of the support, and wherein the skirt is oriented on the device as to inhibit blood flow between the prosthetic treatment device and the native valve.
