Balloon mitral spacer

摘要

A heart valve implant according to one embodiment may include a shaft and an anchor disposed on one end of the shaft, the anchor configured to engage tissue. The heart valve implant may further include an expandable member disposed over at least 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 expandable member defining a chamber and being configured to receive an inflation medium in the chamber to expand the expandable member, the expandable member further configured to deform upon contact with at least a portion of at least one leaflet of a heart valve to at least partially conform to the shape of the leaflet.

1. A method comprising:
providing a heart valve implant comprising heart valve implant:
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; anda 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 a heart valve during systole upon contact with at least a portion of at least one leaflet of the heart valve; at least partially collapsing the heart valve implant; percutaneously inserting the at least partially collapsed heart valve implant into a heart; securing the at least partially collapsed heart valve implant within the heart; and expanding the collapsed heart valve implant 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.
