Abstract
Disclosed are devices and methods for treating regurgitation through a valve in the heart. The devices can include an expandable, fluid-tight bladder configured to be deployed between valve leaflets of the heart valve. The bladder can include an upper portion that extends into the atrium of the heart; a lower portion that extends into the ventricle of the heart; and a middle portion positionable within the line of valve leaflet coaptation that provides a sealing surface for one or more of the leaflets.
Claims5
A device for treating regurgitation through a gap in a valve in a heart, the heart having an atrium fluidically coupled to a ventricle by the valve, the valve including at least two leaflets which coapt along a line of coaptation, the device comprising:
- a frame sized to fit within a heart chamber;
- a pair of arms moveably coupled to the frame, the arms are structurally configured to move from a fluid flow-blocking position during a systole to a fluid flow-allowing position during a diastole in response to pressure changes occurring between the systole and the dystole;
- an anchoring mechanism having a tether and an anchor positioned in a wall of the ventricle, wherein the tether interconnects the frame to the anchor;
- and
- a compliant membrane covering the frame and at least a portion of the pair of arms,
- wherein the frame further comprises a stationary portion coupled to a proximal portion of the pair of arms, wherein the stationary portion is positioned above the level of the annulus and wherein the stationary portion has a long axis oriented orthogonal to the line of coaptation.
