Systems and methods for improving cardiac function

A device configured for delivery to a heart of a patient, the device comprising:

• a plurality of radially expandable resilient ribs connected at their distal ends to a central hub;
• and
• a membrane coupled to the ribs, wherein the ribs are adapted to anchor to a wall of a ventricle of the heart and the membrane is adapted to separate the left ventricle into a main functioning portion and a secondary, essentially non-functioning portion thereby reducing pressure acting on the non-functioning portion.

A device for implantation within a ventricle of the heart, the device comprising:

• an expandable frame formed from a plurality of ribs extending from a first end of a central hub and a support component extending from a second end of the central hub;
• and
• a membrane secured to the plurality of ribs, the membrane having a peripheral portion configured to form a seal against a ventricle wall and an interior portion configured to be spaced away from the ventricle wall by the support component, wherein the interior portion of the membrane is adapted to provide a trampoline effect wherein a pressure receiving face of the interior portion of the membrane is configured to move in a first direction during systole and a second direction during diastole.
