Abstract
A pouch to at least partly enclose a heart (1), the wall of the pouch (2) being elastic. The purpose of the pouch is to enclose at least part of a heart (1) and to oppose excessive dilation of the heart (1) that might be due to infectious disease of the heart muscle, for instance a viral infection or an autoimmune process. In many cases the use of such a pouch (2) may circumvent the need for a heart transplant.
