Publication number: 20090036730Abstract: A direct cardiac assist device which may aid in ventricular recovery. The device proactively modulates cardiac strain pattern to produce a contraction strain pattern that induces beneficial growth and remodeling of the myocardium or prevents or reduces apoptosis of the myocytes. The device may include an outer shell. membrane, or mesh and an inner membrane. The space between the outer member and the membrane may be filled with fluid that is pressurized during contraction. The device prescribes a beneficial strain pattern during heart contraction. This strain pattern does not invert the curvatures or grossly alter the curvatures of the heart and may assist in myocyte regrowth and healing of the failing heart.Type: ApplicationFiled: September 30, 2008Publication date: February 5, 2009Applicants: The Texas A&M University System, Corinnova IncorporatedInventors: John C.
