Abstract

Synthetic polymer biomaterials are often asked to perform under conditions of large cyclic deformations for long lifetimes. Typical of such applications are Left Ventricular Assist (LVA) pump bladders, heart valve components, and vascular grafts. In designing with these materials and eventually qualifying them for clinical usage, it is necessary to be able to predict the fatigue lifetimes accurately and reliably. To be sure, these materials must be biologically compatible; but even the most perfectly biocompatible material will not be qualified for structural use in humans unless its mechanical longevity can be proven from an accurate data base.
