Implantable neurostimulation systems and methods thereof
First Claim
1. A neurostimulation system for deep brain stimulation, the neurostimulation system comprising:
- a burr hole plug comprising a cover and a base;
at least one deep brain stimulation (DBS) lead extending through an aperture defined through the base, the at least one DBS lead including at least one DBS electrode configured to apply stimulation to a subject;
an implantable pulse generator (IPG);
an extension electrically coupling the IPG to the at least one DBS lead; and
an indifferent electrode positioned proximate the at least one DBS electrode to facilitate reducing an area between the indifferent electrode and the at least one DBS electrode;
the base including a metallic bottom, the metallic bottom comprising the indifferent electrode, with the indifferent electrode being sized and shaped to facilitate preventing heating during application of radio frequency fields; and
the at least one DBS lead including an indifferent ring and the base including at least one metallic clip with the metallic clip being configured to engage the indifferent ring such that the indifferent ring is electrically coupled to the metallic bottom.
