Abstract
A method of making a high reliability electrical connection in an implantable medical device. The electrical conductors may include metals such as niobium, molybdenum, tantalum, platinum, titanium, nickel and alloys thereof. The electrical conductors are resistance welded by establishing contact between the conductor pair, providing a protective atmosphere around the contacting pair, and applying electrical energy to the contacting pair to cause fusion while maintaining the protective atmosphere.
