    Abstract: An electromagnetic interference immune defibrillator lead has a first electromagnetic insulating layer. A first layer is formed on the first electromagnetic insulating layer, the first layer having a plurality of first conductive rings composed of first conductive material, each first conductive ring being separated by first insulating material. A second electromagnetic insulating layer is formed on the first layer. A second layer is, formed on the second electromagnetic insulating layer, the second layer having a plurality of second conductive rings composed of second conductive material, each second conductive ring being separated by second insulating material. A third electromagnetic insulating layer is formed on the second layer. The second conductive rings of second conductive material are positioned such that a second conductive ring overlaps a portion of a first conductive ring and overlaps a portion of a second conductive ring, the second conductive ring being adjacent to the first conductive ring. The second electromagnetically insulating layer is composed of a self-healing dielectric material.

    Abstract: A process for assisting the function of a heart disposed within a body, comprising the steps of supporting the heart in providing circulation of blood for perfusion of an organ in the body, remodeling the heart to render the heart in an improved state, and stabilizing the heart in the improved state. The process is preferably performed with an apparatus comprising a cup-shaped shell having an exterior surface and an interior surface; a liner having an outer surface, an upper edge joined to said interior surface of said cup-shaped shell, and a lower edge joined of said interior surface of said cup-shaped shell, thereby forming a cavity between said outer surface thereof and said interior surface of said shell; a drive fluid cyclically interposed within said cavity; and at least one sensor measuring at least one macroscopic parameter indicative of said function of said heart. Further embodiments of the process and apparatus include means and use thereof for delivering a therapeutic agent to the heart.
