Abstract
A method for treating a disease of the heart such as congestive heart failure includes forming an access opening from a heart chamber into a pericardial space defined between an epicardial surface of the heart and a pericardium opposing the epicardial surface. A cardiac support member is deployed into said pericardial space through said access opening with said cardiac support member selected to engage an epicardial surface of said heart and relieve a wall tension of said heart.
Claims20
A method for treating a disease of a heart comprising:
- forming an access opening from a heart chamber into a pericardial space defined between an epicardial surface of the heart and a pericardium opposing said epicardial surface;
- deploying a cardiac support member into said pericardial space through said access opening with said cardiac support member selected to engage an epicardial surface of said heart and relieve a wall tension of said heart.
An apparatus for treating a disease of the heart comprising:
- a cardiac support member sized and configured to be passed through an atrial wall of a human heart and reside within a pericardial space defined between opposing surfaces of a pericardium and an epicardium;
- said cardiac support member adapted to be positioned within said pericardial space and opposing a non-resisted diastolic expansion of said heart.
A kit for treating a disease of the heart comprising;
- an introducer for accessing a pericardial space defined between opposing surfaces of a pericardium and an epicardium by passing through atrial wall of a human heart;
- a cardiac support member sized and configured to be passed through said introducer into said atrial wall and be positioned within said pericardial space and opposing a non-resisted diastolic expansion of said heart.
