Implantable medical devices and methods use an intravascular implantable medical device having an elongated housing module to contain one or more circuitry components. An opening is defined through the elongated housing module. A lead, including at least one electrode, is coupled towards the distal end of the elongated housing module and at least a portion of the at least one electrode is in a stowed position within the opening defined through the elongated housing module during implant of the implantable medical device. The at least one electrode is advanceable from the stowed position to a location distal of the distal end of the elongated housing module.
