Visualization of the STN and GPi for DBS

Overview

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.

Full Title of Study: “Visualization of the STN and GPi for DBS Surgery in Patients With Parkinson’s Disease”

Study Type

• Study Type: Observational
• Study Design
  • Time Perspective: Prospective
• Study Primary Completion Date: April 2024

Detailed Description

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.

Interventions

• Device: SIS System
  • FDA-cleared software that enhances standard clinical images for the visualization of structures in the basal ganglia area of the brain which are commonly targeted for DBS lead placement.

Arms, Groups and Cohorts

• SIS Group
  • Standard of care DBS surgery + use of (FDA-cleared) SIS System for preoperative target planning
• Control Group
  • Standard of care DBS surgery and preoperative target planning

Clinical Trial Outcome Measures

Primary Measures

• Primary Outcome
  • Time Frame: 1 day
  • Demonstrate that the distance between the DBS planned target location to the actual implanted lead location is statistically superior in accuracy for the SIS Group as compared with the Control Group

Participating in This Clinical Trial

Inclusion Criteria

• Subject is diagnosed with Idiopathic Parkinson's Disease and is indicated for de novo DBS surgery with bilateral DBS leads implanted in the STN or GPi. – Subject is 18 years or older. – Subject must be able and willing to provide informed consent and comply with study follow-up schedule and procedures. Exclusion Criteria:
