Solid Construct 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 each including at least one passageway configured to be disposed about said shaft, 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 according to one embodiment may include a shaft extending generally along a longitudinal axis of the heart valve implant having at least one anchor configured to be coupled to a first end of the shaft. A spacer may include a plurality of individual segments each including at least one passageway configured to be disposed about the shaft. The plurality of individual segments may define an outer surface of the spacer which is 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. The plurality of individual segments may each having a length and at least one cross-section dimension no larger than an internal cross-section of a lumen of a delivery catheter.
