Abstract
Techniques for minimizing interference between the first and second medical devices or between the different therapy modules of a common medical device are described herein. In some examples, a medical device may include shunt-current mitigation circuitry and/or at least one clamping structure that helps minimize or even eliminate shunt-current that feeds into a first therapy module of the medical device via one or more electrodes electrically connected to the first therapy module. The shunt-current may be generated by the delivery of electrical stimulation by a second therapy module. The second therapy module may be enclosed in a common housing with the first therapy module or may be separate, e.g., a part of a separate medical device.
