Abstract

Abstract A static device for use with the heart that has a plurality of members configured to be positioned adjacent the epicardial surface of the heart. The members are joined by at least one connector wherein the members are fixed in a spatial or spaced relationship relative to each other such that a portion of the heart wall is displaced inwardly.The member(s) can be configured in a rectangular shape, and preferably includes an inner surface having a curved configuration. In one embodiment, the device can have first and second member that are positioned in a spaced relationship relative to each other about 180 degrees apart. The first member is configured to be positioned adjacent the anterolateral surface of the chamber, and the second member configured to be positioned adjacent the posteromedial surface of the chamber.
