Patent ID: 7214181

Claim:
A method for treating cardiac disease of a patient's heart, the heart having a myocardium and ventricular lower extremities comprising a right ventricle and left ventricle, the right and left ventricles being separated by a septum, said method comprising: surgically accessing the patient's heart; positioning a left component portion over the left ventricle, the left component portion comprising a piece of biomedical material having an upper end and a lower end and sized for a distance between said upper end and said lower end to substantially cover said left ventricle and to exert a first pressure on the left ventricle; positioning a right component portion over the right ventricle, the right component portion comprising a piece of biomedical material having an upper end and a lower end and sized for a distance between said upper and said lower end to substantially cover said right ventricle and the exert a second pressure different than the first pressure on the right ventricle; and securing the biomedical material of the left component portion and the right component portion proximate the septum and for said material to conform to an external geometry of the left and right ventricles and for the material to constrain circumferential expansion of the left and right ventricles during diastole and permit unimpeded contraction of the heart during systole.
