Stimulation lead, stimulation system, and method for limiting MRI induced current in a stimulation lead

An implantable stimulation system for electrically stimulating a patient, comprising:

• a pulse generator for generating electrical pulses;
• and
• a stimulation lead that comprises:
• at least one terminal for receiving electrical stimulation;
• at least one electrode for delivering electrical stimulation to tissue of the patient;
• a lead body of an insulative material;
• at least one conductor within the insulative material that electrically couples the at least one terminal with the at least one electrode;
• and a bidirection frequency dependent current limiter (BFDCL) circuit that limits a magnitude of current that can flow through the at least one conductor from the at least one terminal to the at least one electrode, wherein the BFDCL circuit comprises:
• a passive frequency dependent network element;
• first and second semiconductors that each comprise source, drain, and reference terminals, wherein the source terminals of the first and second semiconductors are coupled to respective ends of the passive frequency dependent network element, the source terminal of the first semiconductor is coupled to the reference terminal of the second semiconductor, and the source terminal of the second semiconductor is coupled to the reference terminal of the first semiconductor.
