Abstract:
A method of forming a medical device contact element includes annealing an elongated rod of Ti-15Mo alloy material to form an annealed rod having a Young's Modulus of less than 13.5 Mpsi and an elastic range or strain of at least 0.7%. Then forming a contact ring element from the annealed rod and assembling the contact ring element into a medical device. Contact rings and lead receptacles including the same are also described.
