Brief Summary:
This study is designed to demonstrate an in-house developed re-attachable stereotactic system that can markedly reduce the overall deep brain stimulation (DBS) procedure time to greatly facilitate subject access to neurosurgical restorative therapies. Subjects will consist exclusively of individuals who have been approved to undergo deep brain stimulation surgery for the treatment of a neurological disorder at Mayo Clinic - Rochester MN. This study is a quantitative comparative, between-subject study enrolling approximately 10 subjects.

Arm Intervention/treatment
Experimental: D1 Stereotactic System Assessment
Participants in the clinical study will consist of subjects approved to undergo deep brain stimulation surgery for the treatment of a neurological disorder at Mayo Clinic. Subjects will have a Key secured to their skull for attachment of an MRI-compatible localizer box or D1 stereotactic frame. 3D Euclidian distance error(s), trajectory accuracy(s), operating room time, and comfort level of the system will be assessed.
Device: DBS Electrode Implantation using D1 Sterotactic System
Treatment intervention will consist of subjects undergoing Mayo Clinic standard deep brain stimulation surgery specific to their diagnosed neurological disorder consisting of implantation of stimulating electrodes using the D1 stereotactic system.

Primary Outcome Measures :
  1. 3D Euclidian distance error [ Time Frame: Within 1 month post-DBS surgery. ]
    3D Euclidian distance error between the MR planned coordinate (XP, YP, ZP) and CT confirmed actual DBS coordinate (XA, YA, ZA) will be calculated. The 3D distance error comparable or lower to conventional system will be accounted as success criteria.

  2. Trajectory accuracy [ Time Frame: Within 1 month post-DBS surgery. ]
    A trajectory accuracy will be determined by comparing Collar Angle (CA) and Arc Angle (AA) between MR planned angles (CAP and AAP) and CT confirmed actual angles (CAA and AAA). The non-significant difference between MR planned and CT confirmed angles will be accounted as success criteria.

  3. Operating room time [ Time Frame: Within 1 month post-DBS surgery. ]
    Operating room time will be counted and compared to conventional procedure (using Leksell frame). The average operating room time will be compared between conventional procedure and D1 Stereotactic System procedure. Significantly lower operating room time will be accounted as success criteria

  4. Comfort level questionnaire [ Time Frame: Within 1 month post-DBS surgery. ]
    Comfort level questionnaire will be given to each subject after DBS surgery and removal of the device to assess their overall experience with device and surgery.
