STIMULATION LEAD, STIMULATION SYSTEM, AND METHOD FOR LIMITING MRI INDUCED CURRENT IN A STIMULATION LEAD
摘要:
In one embodiment, a percutaneous stimulation lead for applying electrically stimulation pulses to tissue of the patient comprises: a plurality of electrode assemblies electrically coupled to a plurality of terminals through a plurality of conductors of the stimulation lead, wherein each electrode assembly is disposed in an annular manner around the lead body and each electrode assembly comprises (i) an electrode adapted to deliver electrical stimulation to tissue of a patient, (ii) an interior conductive layer, and (iii) a dielectric layer disposed between the electrode and the interior conductive layer; the electrode and interior conductive layer being capacitively coupled, the dielectric layer further comprising an inductor, the inductor being electrically connected to one of the plurality of conductors through the interior conductive layer, and the inductor being electrically coupled to the electrode.
