Abstract
A reversibly adjustable heart harness is configured to surround at least a portion of a heart and to provide a compressive force to the heart during at least a portion of a cardiac cycle. The heart harness includes a plurality of wires forming a mesh structure, and one or more tensioning motors connected to the mesh structure. The one or more tensioning motors are configured to selectively increase or reduce tension in the mesh structure to readjust the compressive force provided that the heart harness provides to the heart.

A reversibly adjustable heart harness configured to surround at least a portion of a heart and to provide a compressive force to the heart during at least a portion of a cardiac cycle, the heart harness comprising:
- a plurality of wires forming a mesh structure;
- and
- one or more tensioning motors connected to the mesh structure, the one or more tensioning motors configured to selectively increase or reduce tension in the mesh structure to readjust the compressive force provided by the heart harness to the heart.
A method for treating a heart with a compressive force during at least a portion of a cardiac cycle, the method comprising:
- implanting a reversibly adjustable heart harness around at least a portion of the heart, the heart harness comprising a mesh structure and one or more tensioning motors connected to the mesh structure;
- and
- after implantation, applying an external magnetic field to the one or more tensioning motors to selectively increase or reduce tension in the mesh structure to readjust the compressive force provided by the heart harness to the heart.
