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 configured to interact with at least a portion of at least one cusp of a patient'"'"'s heart valve to at least partially restrict a flow of blood through said heart valve in a closed position, said spacer comprising at least one segment configured to be coupled to said shaft while disposed within a patient'"'"'s heart; 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.
