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
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.

20. A method of introducing a heart valve implant with respect to a heart valve comprising:
-
providing a heart valve implant comprising a shaft, at least one anchor configured to be coupled to said shaft, and a spacer including a plurality of individual segments including a first and at least a second 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; 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 (21, 22, 25, 26, 27)

28. A heart valve implant system comprising:
-
a catheter including a lumen; and 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 and having at least one cross-sectional dimension that is larger than an internal cross-section of said lumen, 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 at least one anchor configured to be coupled to a first end region of said shaft. - View Dependent Claims (29, 30, 31, 32)
