Conformable prostheses for implanting two-piece heart valves and methods for using them
First Claim
1. A prosthetic heart valve for implantation at a biological annulus, the prosthetic heart valve comprising:
- a sealing member comprising an annular member, a fabric member, and a baleen element, the sealing member having a first diameter in a contracted state and a second diameter in an expanded state, the second diameter being greater than the first diameter, the fabric member covering at least a portion of the baleen element and at least a portion of the annular member, wherein, in the contracted state, the baleen element is compressed against the annular member and in the expanded state, an angle between the annular member and the baleen element increases such that the baleen element billows at least a portion of the fabric member outwardly away from the annular member as the sealing member transitions from the contracted state to the expanded state within the biological annulus;
wherein the baleen element is positioned exterior with respect to the annular member in both the contracted and expanded states;
the sealing member further having a lattice extending around a circumference of the annular member; and
a valve member attached to the sealing member.

Abstract
A heart valve assembly includes an annular prosthesis and a valve prosthesis. The annular prosthesis includes an annular ring for dilating tissue within a biological annulus and a conformable sewing cuff extending radially from the annular member. The valve prosthesis includes a frame and a valve component. The annular ring is introduced into the biological annulus to dilate tissue surrounding the biological annulus and the sewing cuff conforms to tissue above the biological annulus. Fasteners are directed through the sewing cuff to secure the annular prosthesis to the biological annulus. The annular prosthesis may include a baleen element for biasing fabric on the annular ring outwardly to enhance sealing against the biological annulus. A valve prosthesis is then advanced into the sinus cavity, and secured relative to the annular prosthesis. The sewing cuff may enhance a seal between the valve prosthesis and annular prosthesis.

15. A prosthetic heart valve for implantation in a biological annulus, the prosthetic heart valve comprising:
-
an expandable sealing member comprising an annular ring and a sewing cuff extending from the annular ring, a fabric covering, and a baleen element, wherein fabric covering covers at least a portion of the baleen element, wherein in a contracted state, the baleen element is compressed against the annular member and in an expanded state, an angle between the annular member and the baleen element increases and an angle between the sewing cuff and the baleen element decreases such that the baleen element billows at least a portion of the fabric covering outwardly away from the annular ring as the sealing member transitions from the contracted state to the expanded state within the biological annulus;
wherein the baleen element is positioned exterior with respect to the annular ring in both the contracted and expanded states; anda valve member attached to the expandable sealing member. - View Dependent Claims (16, 17, 18)
