Abstract
An experimental and analytical approach were performed to study the biomechanics of a self-expanding, nitinol transcatheter aortic valve (TAV) stent device deployed in porcine heart tissue. The radial force, pullout force, and coefficient of friction (COF) were quantified, and the interacting device tissue response was investigated. The preliminary data generated from this study may provide a useful measure for determining an adequate valve oversize in aiding against device migration.
