Abstract

An implantable medical device for delivering electrical cardiac therapy includes a first implantable housing containing a battery. There is also a second implantable housing separate from the first implantable housing and containing at least one of: electronic circuitry adapted to evaluate and initiate electrical cardiac therapy, a storage capacitor and an electrode structure comprising a sensing electrode, a pacing electrode and a therapy electrode. The electronic circuit, the storage capacitor or the electrode structure are electrically connected to the battery. Alternatively, there is an implantable medical device for delivering electrical cardiac therapy having an implantable structure containing the following electrically connected components: a battery, electronic circuitry adapted to evaluate and initiate electrical cardiac therapy, a storage capacitor and an electrode structure comprising a sensing electrode, a pacing electrode and a therapy electrode. A method of providing electrical cardiac therapy is also provided.
