Abstract

One aspect is a method of coupling an insulator to a surrounding ferrule in an implantable medical device. An insulator is provided having a plurality of conducting elements extending therethrough. The insulator is placed with conducting elements within a ferrule having a frame-like shape surrounding the insulator along an interface. The insulator is heated with a first laser until raising the temperature of insulator to a first temperature level. The ferrule is welded to the insulator along the interface with a second laser once the insulator has reached the first temperature.
