Abstract
Abstract A geometric reconfiguration assembly for the natural heart having a collar configured for surrounding the natural heart. The collar can include a plurality of supports configured for positioning on the epicardial surface of the heart. Supports can be joined with connectors that can permit or provide slight deformation of the assembly. An external shell or skin portion can be provided around the supports an/or connectors.
