Implantable medical device including two power sources
First Claim
1. An implantable medical device (IMD) comprising:
- a cardiac stimulation module which provides at least one stimulation therapy selected from a group consisting of;
pacing;
cardioversion; and
defibrillation;
an electrical stimulation module which provides electrical stimulation therapy;
a first power source, wherein the first power source provides power to the cardiac stimulation module and not to the electrical stimulation module; and
a second power source, wherein the second power source provides power to at least the electrical stimulation module.

Abstract
An implantable medical device (IMD) may include a battery dedicated to providing cardiac stimulation therapy and a separate power source that provides power for electrical stimulation therapy. Such a configuration preserves the battery dedicated for providing cardiac stimulation therapy even if the second power source is depleted. As an example, the IMD may comprise a cardiac stimulation module configured to deliver at least one stimulation therapy selected from a group consisting of pacing, cardioversion and defibrillation. The IMD further comprises a electrical stimulation module configured to deliver electrical stimulation therapy, a first power source including a battery, wherein the first power source is configured to supply power to the cardiac stimulation module and not to the electrical stimulation module, and a second power source. The second power source is configured to supply power to at least the electrical stimulation module.
