Balloon mitral spacer
First Claim
1. A heart valve implant comprising:
- a shaft;
an anchor coupled to one end of the shaft, the anchor configured to secure the heart valve implant to a patient'"'"'s heart;
an expandable member coupled to a part of the shaft, the expandable member comprising a resiliently deformable internal layer and a resiliently deformable external layer disposed over the internal layer, the resiliently deformable internal layer comprising a scaffold, wherein the expandable member defines a chamber configured to receive an inflation medium from an inflation device and to expand the expandable member from a compressed position to an expanded position; and
a valve configured to seal said inflation medium within said chamber in the expanded position after disconnection from said inflation device such that the expandable member, when in the expanded position, is configured to at least partially restrict a flow of blood through the heart valve during systole upon contact with at least a portion of at least one leaflet of a heart valve.
