Abstract
An apparatus for treatment of a failing heart by reducing the wall tension therein. In one embodiment, the apparatus includes a tension member for drawing at least two walls of a heart chamber toward each other. Methods for placing the apparatus on the heart are also provided.
Claims45
A system for reducing tension in a wall of a chamber of a heart, the system comprising:
- a first member configured to be positioned transverse the chamber for drawing first portions of the chamber wall toward each other so that the first portions remain in a non-contacting relationship;
- and
- a second member configured to be positioned transverse the chamber and proximate and substantially parallel to the first member for drawing second portions of the chamber wall toward each other so that the second portions remain in a non-contacting relationship.
An system for reducing tension in a wall of a chamber of a heart, the system comprising:
- a first member configured to be positioned transverse the chamber for drawing first portions of the chamber wall toward each other so that all interior parts of the chamber remain in direct fluid communication;
- and
- a second member configured to be positioned transverse the chamber and proximate and substantially parallel to the first member for drawing second portions of the chamber wall toward each other so that all interior parts of the chamber remain in direct fluid communication.
A system for reducing tension in a wall of a chamber of a heart, the system comprising:
- a first member configured to be positioned transverse the chamber for altering a shape of the chamber so that all interior parts of the chamber remain in direct fluid communication;
- and
- a second member configured to be positioned transverse the chamber and proximate and substantially parallel to the first member for altering the shape of the chamber so that all interior parts of the chamber remain in direct fluid communication.
A method for placing an apparatus on a heart, the apparatus for reducing tension in a wall of a chamber of a heart, the method comprising the steps of:
- extending a hollow needle through the chamber such that each end of the needle is external to the chamber;
- advancing the apparatus through the needle until a first end of the apparatus is external to the chamber;
- coupling the first end of the apparatus to a first exterior portion of the chamber;
- and coupling a second end of the apparatus to a second exterior portion of the chamber.
