Abstract
A flow-balanced cardiac wrap that assists the right and left ventricles of an affected heart to differing, and adjustable degrees is provided. The wrap generally applies an assist to the left ventricle that is greater than that applied to the right, or that reduces blood output from the right relative to the left. In one embodiment, the wrap comprises a material covering that is applied around the right and left ventricles of the heart, so that the left ventricle is assisted over a larger surface area than the right. The positioning of the right ventricular portion or the wrap is chosen so that desired pumping characteristics for the right ventricle are achieved.
