Abstract

A cardiac restraint device includes a central cavity that receives the heart. A chamber surrounding the cavity presses against the surface of the heart when the chamber is filled with fluid. The inner wall defining the chamber is deformable, so that it tends to expand into the cavity and contact the heart. The outer wall of the chamber, or alternatively, a jacket surrounding the chamber, is nondeformable, so that expansive forces of the fluid in the chamber tend to be directed inward against the heart rather than outward.
