Abstract
Prosthetic heart valves having elastic leaflets and an elastic support structure are described. The support structure can store a load transferred from the leaflets as potential energy and then release it in the form of kinetic energy to exhibit a precursory transition from the closed position to the open position. The support structures can exhibit a sinusoidal movement profile at a base edge during the precursory transition.
