    摘要： Techniques for minimizing interference between first and second medical devices of a therapy system may include providing an outer housing for at least one of the medical devices that comprises an electrically insulative layer formed over at least the electrically conductive portions (e.g., an electrically conductive layer) of the housing, or providing an electrically insulative pouch around an electrically conductive housing of at least the first medical device. The electrically insulative layer or electrically insulative pouch may reduce or even eliminate shunt-current that flows into the medical device via the housing. The shunt-current may be generated by the delivery of electrical stimulation by the second medical device. In some examples, the techniques may also include shunt-current mitigation circuitry that helps minimize or even eliminate shunt-current that feeds into the first medical device via one or more electrodes electrically connected to the first medical device.

    摘要： The disclosure describes techniques of reducing or eliminating a commonality between two modules within the same implantable medical device. Each module within the implantable medical device provides therapy to a patient. The commonality between the two modules exists due to at least one common component shared by the two modules. The commonality between the two modules may create common-mode interference and a shunt current. In accordance with this disclosure, various isolation circuits located at various locations are disclosed to reduce or eliminate the commonality between the two modules. The reduction or elimination of the commonality between the two modules may reduce or eliminate common-mode interference and the shunt current.

    摘要： An electrical parameter value indicative of an impedance of an electrical path between a first medical device implanted within a patient and a second medical device implanted within the patient may be determined by generating and delivering an electrical signal between electrodes connected to the first medical device and sensing the electrical signal with two or more sense electrodes connected to the second medical device. In some examples, the electrical parameter value indicative of the impedance may be used to detect a system integrity issue, such as relative movement between the first and second medical devices, such as between leads connected to the medical devices, or a lead-related condition. In other examples, the determined impedance may indicate a transthoracic impedance of the patient.

    摘要： An implantable medical system that includes a cardiac therapy module and a neurostimulation therapy module may identify when neurostimulation electrodes have migrated toward a patient's heart. In some examples, the system may determine whether the neurostimulation electrodes have migrated toward the patient's heart based on a physiological response to an electrical signal delivered to the patient via the neurostimulation electrodes. In addition, in some examples, the system may determine whether the neurostimulation electrodes have migrated toward the patient's heart based on an electrical cardiac signal sensed via the neurostimulation electrodes.
