First Implant of Activa PC+S Deep Brain Stimulation System Initiates Research That Could One Day Significantly Change How Neurological and Psychological Diseases are Treated

Medtronic, Inc. has announced the first implant of a novel deep brain stimulation (DBS) system that, for the first time, enables the sensing and recording of select brain activity while simultaneously providing targeted DBS therapy. This initiates research on how the brain responds to the therapy and could yield insights that one day significantly change the way people with devastating neurological and psychological disorders, such as Parkinson's disease, essential tremor, dystonia, and treatment-resistant obsessive-compulsive disorder, are treated.

The Activa® PC+S DBS system delivers proven Medtronic DBS Therapy while at the same time sensing and recording electrical activity in key areas of the brain using sensing technology and an adjustable algorithm, which enable the system to gather brain signals at various moments as selected by a physician.  Initially, this new technology will be made available to a select group of physicians worldwide for use in clinical studies. These physicians will use the system to map the brain's responses to Medtronic DBS Therapy and explore applications for the therapy across a range of neurological and psychological conditions.  

The Activa PC+S system, which delivers stimulation to targeted areas of the brain like existing Medtronic DBS systems, was implanted for the first time at Ludwig Maximilians University in Munich, Germany in a person with Parkinson's disease. This patient will be treated by a team that includes neurologist Kai Bötzel, department of neurology, Ludwig Maximilian University and neurosurgeon Jan Mehrkens, M.D., head of functional neurosurgery, Ludwig Maximilian University, who implanted the system.

Dr. Bötzel will be the first to use data gathered by the Activa PC+S system to gain unprecedented insight into how the brain responds to DBS therapy.

"DBS therapy works for people with Parkinson's disease and other movement disorders, but there is much to learn about how the brain responds to the therapy," said Dr. Bötzel. "This new system will allow us to treat patients with conventional DBS therapy, while at the same time opening the door for research that was not possible until now. We hope these insights will lead to the development of effective new treatments tailored to the needs of individuals."

"Devastating conditions like Parkinson's disease and obsessive-compulsive disorder take a significant toll on countless people, as well as their loved ones," said Lothar Krinke, Ph.D., vice president and general manager of the Deep Brain Stimulation business in Medtronic's Neuromodulation division. "Medtronic is excited to provide this new system to researchers worldwide, and we expect that their respective studies will lead to accelerated understanding of how neurological and psychological conditions develop and progress. This represents a significant milestone for DBS therapy and the long-term journey toward a closed-loop DBS system, which could personalize therapy by using device data to automatically adjust to the needs of individual patients."

Medtronic's Activa PC+S system received CE (Conformité Européenne) mark in January 2013. It is not approved by the U.S. Food and Drug Administration for commercial use in the United States, and will be made available to select physicians for investigational use only. Additional implants of the Activa PC+S system, including the first implant in the United States, will take place in the coming months.
