Evaluation of high compliant elastomer balloons for the identification of artery biomechanics

Abstract

With a Finite Element Analysis (FEA) study the capability of elastomer balloons for the in-vivo identification of parameters for Strain Energy Function (SEF) based tissue models is investigated. Multiple Combinations were obtained by varying balloon thickness and radius. Each combination was simulated inside a carotid artery based on a hyperelastic model. As the chosen analytical formulation for parameter fitting suits well the simulated FEA model, all balloons can analyze the parameters with a relative error below 2 %. For real world correlates however, the analytical fit and the sensor sensitivity determine the accuracy of obtainable results.
