Intraoperative Neural Sensing for Deep Brain Stimulation (DBS)

A method for providing electrical stimulation to a patient's brain using one or more electrode leads implantable in the patient's brain, wherein each of the one or more electrode leads comprise a plurality of distal electrode contacts configured to contact the patient's brain and a plurality of proximal electrode contacts outside the patient's brain, the method comprising:

• providing an operating room (OR) cable comprising:
• a proximal end configured to connect to an external trial stimulator (ETS),
• a distal end comprising one or more electrode lead connectors configured to connect to the proximal electrode contacts of the one or more electrode leads, and
• at least two off-lead electrode connectors configured to connect to off-lead electrode contacts that are not configured within the one or more electrode leads,
• connecting the proximal end of the OR cable to the ETS,
• connecting the one or more electrode lead connectors to the proximal electrode contacts of the one or more electrode leads,
• connecting a first of the at least one of the off-lead electrode connectors to a first off-lead electrode,
• configuring the first off-lead electrode to have electrical continuity with the patient, and
• using the ETS to provide one or more stimulation waveforms to one or more of the plurality of proximal electrode contacts of the one or more electrode leads.
