Devices and methods providing for a isolation connector for a generally cylindrical or frustro-cylindrical housing of an implantable intravascular medical device are described herein. The isolation connector has a generally annular exterior surface, a proximal end, and a distal end. The isolation connector includes a housing interface portion at the proximal end which is secured to a first end of the housing. The proximal end of the housing interface portion is constructed to be obverse to the first end of the housing and presents a perimeter of substantially similar size and shape to the perimeter of the first end of the housing. The isolation connector further includes a first insulator portion disposed adjacent to a distal end of the housing interface portion. The isolation connector may further include a feed-through channel constructed to traverse the proximal and distal ends of the isolation connector and is defined through the housing interface portion and the first insulator portion. In an optional embodiment, an electrical conductor is disposed within the feed-through channel to electrically coupled at least one component disposed within the housing to at least one component disposed beyond the insulator portion.
