Abstract: An implantable medical device system is configured to generate signals and deliver the signals to a heart of a patient. The implantable medical device system includes electronic circuitry configured to deliver cardiac pacing, couplings for an implantable medical lead receptacle, at least some of the couplings electrically connected with the electronic circuitry, a polymeric enclosure having the electronic circuitry contained therein, the polymeric enclosure formed of polymeric material filled around the electronic circuitry and couplings and forming the implantable medical lead receptacle. The implantable medical device may include a first cavity filled with a first material and a second cavity filled with a second material, and the first material is different than the second material.
