1. A method for enhancing displacement-controlled fatigue performance, increasing ductility or decreasing modulus of a structural element of an implantable medical device, wherein the structural element comprises a shape memory alloy material, the method comprising:
a first step consisting essentially of: heating the structural element at a temperature between 580° C. and 620° C. for a time between 30 seconds and 500 minutes to produce a heat-treated structural element; and
a second step comprising: shape setting the heat-treated structural element after the structural element is heated.
