Robotic arm used in DBS implantation

University of Minnesota Health neurosurgeons can now turn to a robotic surgical device to help implant electrodes for deep brain stimulation (DBS) in patients with Parkinson’s disease and reduce patients’ time in surgery. Designed for minimally invasive cranial procedures, the robotic arm known as ROSA (Zimmer Biomet, formerly MedTech Innovative Surgical Technology) helps achieve precise placement of electrodes in the target area, a factor critical to effective DBS therapy. Electrodes misplaced by as little as 1 mm can reduce DBS’s effectiveness. The robotic arm is the first such device used in Minnesota and is being used for implanting depth electrodes and response neural stimulator NeuroPace in patients who have epilepsy.

Ongoing recruitment for DBS clinical trial

A multisite clinical trial investigating a new deep brain stimulation system as a treatment for Parkinson’s disease is now enrolling participants at University of Minnesota Health locations. The study of the Vercise™ DBS System (Boston Scientific) seeks patients who have advanced levodopa-responsive, bilateral Parkinson’s disease not adequately controlled with medication. The study will compare 2 types of stimulation to determine their effectiveness. University of Minnesota Health neurologist Jerrold L. Vitek, MD, PhD, serves as 1 of the principal investigators. To refer patients, physicians should contact Boston Scientific at 855-213-9890.

Directional electrode for DBS in Parkinson’s disease

University of Minnesota Health patients now have access to a new deep brain stimulation system for the treatment of Parkinson’s disease and other movement disorders. Approved for use in the United States, the Infinity™ DBS System from Abbott (formerly St. Jude Medical) uses a directional electrode, which allows neurosurgeons to more precisely direct electrical stimulation towards the desired area by selectively turning on and off contacts. This feature permits selective stimulation of targeted tissue. This electrode provides effective therapy without the side effects, such as muscle contractions, that can be produced by other types of electrodes that generate signals in all directions, stimulating nontarget tissues. M Health physicians are the first in the state to implant the new electrode.
