1. A diastolic recoil device adapted for percutaneous delivery to a heart of a patient comprising a plurality of radially expandable resilient ribs connected at their distal ends to a central hub, and a membrane coupled to said ribs, wherein said ribs are adapted to anchor to a wall of a ventricle of said heart to store energy provided by said ventricle during systole and to provide an elastic recoil force to said wall of said ventricle during diastole.

11. A method of treating a patient suffering from a heart condition comprising:
-
advancing percutaneously a collapsed diastolic recoil device comprising a plurality of radially expandable resilient ribs connected at their distal ends to a central hub, said device further comprising a membrane coupled to said ribs; expanding said ribs in a ventricle of said heart; partitioning said ventricle with said membrane; and
,securing said device to opposing walls of said ventricle thereby providing elastic support between said opposing ventricular walls. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

- 34. A diastolic recoil device comprising a plurality of resiliently deformable ribs and a plurality of anchors, and a membrane coupled to said ribs, said device being adapted to be delivered percutaneously to and anchored within the interior of a ventricle of a patient'"'"'s heart to span a region of said ventricle, said resiliently deformable member being adapted to deform from a first shape to a second shape during systole and to return to said first shape during diastole to assist in expansion of said ventricle.

44. A method of treating a patient suffering from a heart condition comprising:
-
advancing percutaneously to the interior of a ventricle of the patient'"'"'s heart a diastolic recoil device comprising a resiliently deformable member and a plurality of anchors; securing said devices to opposing wall sections of said ventricle with said anchors; deforming said deformable member as said opposing wall sections move toward each other during systole; and providing a recoil force from said deformable member to said wall sections during diastole. - View Dependent Claims (45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65)

66. A method of treating a patient suffering from a heart condition comprising:
-
advancing percutaneously to the interior of a ventricle of the patient'"'"'s heart a diastolic recoil device comprising a resiliently deformable member and a plurality of anchors; securing said device to opposing wall sections of said ventricle with said anchors; storing energy within said deformable member as said opposing wall sections move toward each other during systole; and releasing energy from said deformable member to said wall sections as said opposing wall sections move away from each other in synchrony with a heart cycle.
