Visualization of the STN and GPi for DBS

The purpose of the study is to determine if using SIS System for DBS planning results in less distance between the planned target location and the actual implanted lead location than DBS planning without SIS System.

This is a prospective, controlled, open-label, multicenter post-market trial to compare standard of care DBS surgery to standard of care plus visualization with the SIS System. The purpose of the study is to determine if using SIS System for DBS planning results in less distance between the planned target location and the actual implanted lead location than DBS planning without SIS System. Parkinson's Disease subjects indicated for DBS will undergo standard DBS surgery with preoperative planning for targeting of STN or GPi as indicated. Subjects will be followed through six months after initial DBS programming to collect clinical outcomes.
