Patent ID: 7704277

Claim:
A device for treating mitral valve regurgitation comprising: a coaptation member having an elongated cross-sectional profile wherein a width in a first radial direction is substantially smaller than a length in a second radial direction, the elongated shape sized for placement at least partially between leaflets of a native mitral valve, said coaptation member adapted for expansion in said first radial direction for increasing said width while said length remains substantially constant and wherein said expansion of said coaptation member in said first radial direction restricts blood flow between said leaflets and said coaptation member and wherein a contraction of said coaptation member in said first radial direction allows blood to flow between said leaflets and said coaptation member; a support structure coupled to said coaptation member, the support structure constructed to provide said coaptation member with said elongated cross-sectional profile, and an anchoring structure comprising an anchoring wire that comprises a plurality of loops formed of a shape memory material, said anchoring structure connected to said coaptation member, said anchoring structure having a compressed state sized to fit within a delivery catheter and an expanded state sized to conform to a left atrium for fixation along an inner wall of the left atrium.
