The purpose of this study is a small, first in man, clinical feasibility trial for patients with severe Parkinson's Disease (PD), who are already clinically eligible for deep brain stimulation (DBS) with two goals: to compare efficacy from two common sites of DBS (subthalamic nucleus (STN), and globus pallidus interna (GPi)) through the implantation of dual DBS electrodes on each side of the brain; and to develop a closed loop DBS system using evoked and spontaneous potentials derived from these two electrodes. The study will involve bilateral dual DBS electrode placement in clinically standard locations (ie, STN and GPi) unilaterally or (more often) bilaterally, the placement of the RC+S Medtronic research implantable pulse generator (IPG), and a commitment to return for both extensive postoperative programming and testing to define clinical efficacy and separate research days to develop the closed loop approach. In addition, patients will undergo intraoperative research using temporary percutaneous extensions to the DBS electrode(s) and DBS lead cannula after implantation to confirm the electrode location and to identify what the signals will look like during later chronic recordings through the research IPG. The research RC+S IPG includes both ordinary DBS stimulation as well as a recording system that simultaneously measures the DBS local evoked potential (DLEP) and/or local field potential (LFP) responses from either the same or a second DBS electrode.
