Abstract

A system comprises a plurality of electrodes which can be positioned within the brain of a patient to deliver therapy to the patient or sense electrical activity, a therapy delivery circuit operably coupled to the plurality of electrodes to deliver therapy to the patient, a sensing circuit operably coupled to the plurality of electrodes to sense electrical activity, and a controller comprising a processing circuit system operably coupled to the therapy delivery circuitry and the sensing circuit. The controller is configured to control one or more of the plurality of electrodes to deliver therapy to the patient through the therapy delivery circuit; and in the process of delivering therapy, the sensing circuit is used for sensing the potentials of the plurality of electrodes, and calculating the difference value of the potentials of any two electrodes based on the potentials of the plurality of electrodes so as to obtain the voltage between the any two electrodes.

Description

technical field [0001] The present application relates to the field of implantable medical systems technology, and more particularly to systems for electrical activity sensing, particularly electrical activity sensing while delivering therapy. Background technique [0002] Implantable medical systems generally include implantable nerve electrical stimulation systems, implantable cardiac electrical stimulation systems, and implantable drug infusion systems. [0003] Taking the implanted electrical nerve stimulation system as an example, it mainly includes a pulse generator implanted in the body, electrodes and external control devices. Among them, the pulse generator is connected with the electrode, so that the pulse generated by the pulse generator is transmitted to the electrode, and the pulse signal generated by the pulse generator is transmitted from the electrode to a specific nerve part for electrical stimulation, so that the human body function can be restored to norma...
