Abstract

Abstract Devices and methods for treating heart valves include members that assist the valve in closing during at least a portion of the cardiac cycle. Such devices include members configured to alter the shape of a valve annulus, reposition at least one papillary muscle, and/or plug an orifice of the valve so as to provide a coaptation surface for the valve leaflets.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 97 words
A device for treating leakage of a heart valve, the device comprising: an expandable plug member configured to be implanted relative to the heart and having an external surface, at least a portion of the plug member being configured to be positioned proximate leaflets of the heart valve; and a securement mechanism attached to the plug member and configured to secure the plug member for implantation with respect to the heart, wherein during at least a portion of the cardiac cycle, the leaflets abut the external surface of the plug member to restrict bloodflow through the valve.
Claim 2
Independent Claim 97 words
A device for treating leakage of a heart valve, the device comprising: an expandable plug member configured to be implanted relative to the heart and having an external surface, at least a portion of the plug member being configured to be positioned proximate leaflets of the heart valve; and a securement mechanism attached to the plug member and configured to secure the plug member for implantation with respect to the heart, wherein during at least a portion of the cardiac cycle, the leaflets abut the external surface of the plug member to restrict bloodflow through the valve.
Claim 3
Dependent Claim 12 words
The device of claim 1 , wherein the plug member is inflatable.
Claim 4
Dependent Claim 12 words
The device of claim 1 , wherein the plug member is foldable.
Claim 5
Dependent Claim 26 words
The device of claim 1 , wherein the securement mechanism includes at least one elongate member configured to suspend the plug member between the valve leaflets.
Claim 6
Dependent Claim 33 words
The device of claim 4 , wherein the securement mechanism further comprises at least one anchoring member configured to secure the elongate member to a heart wall surrounding a chamber containing the valve.
Claim 7
Dependent Claim 17 words
The device of claim 5 , wherein the elongate member is in the form of a tether.
Claim 8
Dependent Claim 24 words
The device of claim 1 , wherein at least a portion of the plug member is configured to be positioned between the valve leaflets.
Claim 9
Dependent Claim 27 words
The device of claim 1 , wherein at least a portion of the plug member is configured to be positioned below free ends of the valve leaflets.
Claim 10
Dependent Claim 30 words
The device of claim 1 , wherein at least a portion of the plug member is configured to be positioned approximately at a level of an annulus of the valve.
Claim 11
Dependent Claim 24 words
The device of claim 1 , wherein the plug member is configured to expand and collapse in response to pressure changes in the heart.
Claim 12
Dependent Claim 16 words
The device of claim 10 , wherein the plug member is configured to collapse during systole.
Claim 13
Dependent Claim 16 words
The device of claim 10 , wherein the plug member is configured to expand during diastole.
Claim 14
Dependent Claim 20 words
The device of claim 1 , wherein the plug member defines at least one passage configured to permit bloodflow therethrough.
