Stimulation with utilization of non-selected electrode

摘要

This disclosure describes techniques that support delivering electrical stimulation current via at least two user-selected electrodes of an implantable medical device (IMD) and automatically delivering balancing current below via at least one non-selected electrode. Balancing currents delivered via the at least one non-selected electrode may be configured with an amplitude below a perception threshold of a patient. Delivery of balancing current via the at least one third electrode may allow an implantable medical device to automatically balance the total current delivered to a patient.

主权项

1. A method comprising:
receiving, via a user interface of a programmer device for an implantable electrical stimulator, user input specifying at least one first user-selected electrode to deliver electrical stimulation of a first polarity and at least one second user-selected electrode to deliver electrical stimulation of a second polarity different than the first polarity for delivery of electrical stimulation from an implantable electrical stimulator to a patient; receiving, via the user interface, user input specifying amounts of electrical stimulation current to be supplied via the at least one first user-selected electrode and the at least one second user-selected electrode; automatically selecting, by one or more processors, at least one third electrode not specified as a user-selected electrode to deliver electrical stimulation to substantially balance the electrical stimulation current to be delivered via the at least one first user selected electrode and the at least one second user-selected electrode; and defining a program to control delivery of the electrical stimulation by the stimulator based on the user input.
