Claim Text:
1. A method of securing a feedthrough directly to a metal housing for an implantable medical device, the method comprising: providing the feedthrough comprising an insulating section and at least one conductive section extending through the insulating section; metalizing at least a portion of the insulating section; placing the metalized feedthrough within an opening in the metal housing of the implantable medical device; positioning the feedthrough and metal housing within an ultrasonic welding system; placing a bond material between the feedthrough and the metal housing; and energizing the ultrasonic welding system such that ultrasonic energy welds the feedthrough directly to the metal housing with the bonding material and without any intervening ferrule between the feedthrough and the metal housing, thereby creating a hermetic seal between the feedthrough and housing; characterized in that the temperature of the metal housing is not raised above the β-transus temperature of the metal housing during the ultrasonic welding.
