Mitral spacer
First Claim
1. A heart valve implant comprising:
- a shaft extending generally along a longitudinal axis of said heart valve implant;
a spacer comprising a plurality of individual segments including at least a first segment configured to be coupled to said shaft and at least a second segment configured to be coupled to at least a portion of an outer surface of said first segment, wherein said plurality of individual segments define an outer surface of said spacer configured to interact with at least a portion of at least one cusp of a heart valve to at least partially restrict a flow of blood through said heart valve in a closed position, and wherein at least one of said plurality of individual segments includes a fastener for coupling with an adjacent segment; and
at least one anchor configured to be coupled to a first end region of said shaft.

Abstract
A heart valve implant may include a shaft and an anchor configured to be coupled to an end of the shaft. A spacer may be coupled to a portion of the shaft and comprise a plurality of individual segments including a first and at least a second individual segment. The first segment may be coupled to the shaft. The second segment may be coupled to at least a portion of an exterior surface of the first segment and may have at least one cross-section dimension which is greater than an internal cross-sectional dimension of a delivery lumen. Additional segments may be coupled to an inner, adjacent segment. The segments may include a collapsible body portion to facilitate percutaneously delivery through a lumen. The segments may define an outer surface of the spacer configured to interact with at least a portion of at least one cusp of a heart valve to at least partially restrict a flow of blood through the heart valve in a closed position.

19. A method of introducing a heart valve implant with respect to a heart valve comprising:
-
providing a heart valve implant comprising; a shaft extending generally along a longitudinal axis of said heart valve implant, at least one anchor configured to be coupled to a first end region of said shaft, and a spacer comprising a plurality of individual segments including at least a first segment configured to be coupled to said shaft and at least a second segment configured to be coupled to at least a portion of an outer surface of said first segment, wherein said plurality of individual segments define an outer surface of said spacer configured to interact with at least a portion of at least one cusp of a heart valve to at least partially restrict a flow of blood through said heart valve in a closed position; wherein at least one of said plurality of individual segments includes a fastener for coupling with an adjacent segment serially aligning said plurality of individual segments; percutaneously delivering said shaft and said serially aligned plurality of segments proximate said heart; coupling at least said first segment to said shaft; coupling said at least a second segment to at least a portion of an outer surface of said first segment to define said spacer; and securing said heart valve implant within said heart. - View Dependent Claims (20, 21, 24, 25, 26)
