    摘要： An electromagnetic shield has a first patterned or apertured layer having non-conductive materials and conductive material and a second patterned or apertured layer having non-conductive materials and conductive material. The conductive material may be a metal, a carbon composite, or a polymer composite. The non-conductive materials in the first patterned or apertured layer may be randomly located or located in a predetermined segmented pattern such that the non-conductive materials in the first patterned or apertured layer are located in a predetermined segmented pattern with respect to locations of the non-conductive materials in the second patterned or apertured layer.

    摘要： 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.
