Systems and methods for improving cardiac function

A method of treating a patient suffering from a heart condition, the method comprising:

• advancing a collapsed 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, thereby improving diastolic compliance.

A method of treating a patient suffering from a heart condition, the method comprising:

• advancing a collapsed 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 separating the left ventricle into a main functioning portion and a secondary, essentially non-functioning portion and thereby reducing pressure acting on the non-functioning portion.

A method of treating a patient with a diseased left ventricle, the method comprising:

• advancing percutaneously to the left ventricle an implant having an expandable frame formed from a plurality of ribs extending from a first end of a central hub, a support component extending from a second end of the central hub, and a membrane secured to the plurality of ribs;
• aligning the implant with the left ventricular outflow tract;
• expanding the implant within the left ventricle;
• and
• securing the expanded implant within the left ventricle.

A method of treating a left ventricle of a patient suffering from a heart condition resulting in a left ventricle having a healthy portion and an unhealthy portion, the method comprising:

• percutaneously advancing to the left ventricle an implant having a frame formed from a plurality of ribs and a membrane secured to the frame;
• anchoring the frame in the healthy portion of the left ventricle;
• and
• transmitting motion from the healthy portion of the left ventricle through the plurality of ribs and the membrane to the unhealthy portion of the left ventricle.
