Material Characteristics Ideal for Providing Either Partial or Total Mechanical Support to the Failing or Arrested Heart and Method for Developing Ideal Characteristics for Underlying Cardiac Disorders

Abstract: 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. using an automated drive, the dynamic strain characteristics are compared to the optimal strain characteristics required by the heart to determine if the construct is proper.
