Heart regurgitation method and apparatus
First Claim
1. An implant comprising:
- a shaft;
at least one anchor coupled to a first end region of said shaft; and
at least one conduit coupled to said shaft and configured to engage against at least a portion of a heart valve between a first and a second heart chamber when said implant is extended through said heart valve, wherein said at least one conduit includes a first and a second open end configured to be disposed within said first and said second heart chambers, respectively such that a controlled amount of regurgitation flows into said first open end, through said heart valve, and out said second open end when said heart valve is in a closed position.

Abstract
A regurgitation implant may comprise a conduit or straw which may be coupled to a shaft. The shaft may be coupled to at least one anchor portion configured to couple the regurgitation implant to native coronary tissue. At least a portion of the conduit may be configured to be disposed proximate a mitral valve such that the regurgitation implant may interact and/or cooperate with at least a portion of the native mitral valve to induce a controlled amount of regurgitation through the conduit and therefore through the mitral valve. The regurgitation through the conduit and the mitral valve may cause the heart to dilute in a manner that is generally consistent with advanced disease of the heart. The amount of regurgitation may therefore be adjusted depending on the desired condition of the heart.

13. A regurgitation implant comprising:
-
a shaft; at least one anchor coupled to an end region of said shaft; and at least one conduit coupled to said shaft configured to engage against at least a portion of at least one cusp of a heart valve when said device is extended through said heart valve, so as to at least partially restrict a flow of blood through said heart valve when said heart valve is in a closed position, wherein said at least one conduit defines at least one passageway configured to extend through said heart valve and including a first open end configured to be disposed within a first heart chamber and a second open end configured to be disposed within a second heart chamber such that a controlled amount of regurgitation flows into said first open end, through said heart valve, and out said second open end when said heart valve is in said closed position. - View Dependent Claims (14, 15, 16, 17)

18. A method of inducing regurgitation comprising:
-
providing a regurgitation implant comprising at least one anchor portion and conduit coupled to a shaft; percutaneously inserting said regurgitation implant into a heart; and securing said regurgitation implant within said heart such that said at least one conduit extends through a heart valve between two heart chambers and engages against at least a portion of at least one cusp of said heart valve to define at least one passageway through said heart valve configured to induce a controlled amount of regurgitation through said heart valve in a closed position. - View Dependent Claims (19)
