A system and method for determining the proper dynamic strain profile of an elastomeric construct. The strain characteristics of a deficient heart are determined and compared to the normal strain characteristics of a healthy heart. A construct having elastomeric elements is provided that can expand along multiple axes. In an unloaded condition remote from the deficient heart, the elastomeric elements are pressurized to determine the pressure differential being experienced. Furthermore, optimal strain characteristics are calculated along a first axis and a second axis as a function of the pressure differential. The first optimal strain characteristic and the second optimal strain characteristic are used to estimate the dynamic strain characteristics that will be applied to the heart. The dynamic strain characteristics are compared to the optimal strain characteristics required by the heart to determine if the construct is proper using an automated drive.

A system for treating heart valve malfunction specifically including mitral regurgitation including a positioning structure operative to assume both expanded and contracted orientations and a retaining assembly positioned and structured to operatively dispose the positioning structure in moveably supporting lifting and/or positioning relation to the ventricular wall portion of the heart. The retaining assembly and the positioning structure are cooperatively disposed and structured to accomplish a shape variance of the heart upon a lifting or positioning force being exerted thereon substantially concurrent to the positioning structure being disposed in the expanded orientation. The force exerted on the heart at least partially defines a shape variance thereof to the extent of positioning of the leaflets of the mitral valve into a closed orientation which restricts mitral regurgitation.
