Cardiac disease treatment and device

A method for treating cardiac disease of a patient's heart, said heart having a longitudinal axis from an apex to a base, an upper portion and a lower portion divided by an A-V groove, a valvular annulus adjacent said A-V groove, and ventricular lower extremities adjacent said apex, said ventricular lower extremities comprising a right ventricle and left ventricle wherein said right and left ventricle are separated by a septum, said method comprising:

• surgically accessing said patient's heart;
• positioning material over at least said left ventricle or at least said right ventricle, said material comprising a biomedical material having an upper end and a lower end;
• securing said upper end of said material to said heart;
• and
• adjusting said material on said heart to snugly conform to an external geometry of said heart to constrain circumferential expansion of said heart during diastole and permit unimpeded contraction of said heart during systole, wherein pressure exerted by said device on said right ventricle during diastole is different than pressure exerted by said device on said left ventricle during diastole.

A method for treating cardiac disease of a patient's heart, said heart having a longitudinal axis from an apex to a base, an upper portion and a lower portion divided by an A-V groove, a valvular annulus adjacent said A-V groove, and ventricular lower extremities adjacent said apex, said ventricular lower extremities comprising a right ventricle and left ventricle wherein said right and left ventricle are separated by a septum, said method comprising:

• surgically accessing said patient's heart;
• positioning a first component over a first ventricle, said first component comprising a piece of biomedical material having an upper end and a lower end;
• securing said first component proximate said septum;
• securing said upper end of said material of said first component to said heart;
• adjusting said first component to snugly conform to an external geometry of said heart and assume a maximum adjusted volume for said material to constrain circumferential expansion of said first ventricle beyond said maximum adjusted volume during diastole and permitting unimpeded contraction of said heart during systole;
• positioning a second component over a second ventricle, said second component comprising a piece of biomedical material having an upper end and a lower end;
• securing said second component proximate said septum;
• securing said upper end of said second component to said heart;
• and
• adjusting said second component to snugly conform to an external geometry of said second ventricle and assume a maximum adjusted volume for said material to constrain circumferential expansion of said heart beyond said maximum adjusted volume during diastole and permitting unimpeded contraction of said heart during systole.
