OXNARD, CA – April 18, 2022 – The team at Dignity Health-St. John's Regional Medical Center's (SJRMC) recently became the first and only in Ventura County to implant and activate the most advanced deep-brain stimulation (DBS) technology for patients with Parkinson's disease, essential tremor, dystonia, and other neurological conditions. 

The neuroscience team, led by Akin Oni-Orisan, MD, Medical Director of the Neurointerventional Program, and movement disorder neurologist Bradley Hiner, MD, implanted and activated Abbott's FDA-approved Infinity Deep-Brain Stimulation (DBS) device in a patient living with Parkinson's disease. The patient responded well to treatment and saw significant improvement upon device activation.

"Being the first in Ventura County to adopt the latest DBS technology and the only medical center in this region to offer DBS is a testament to St. John's commitment to staying on the forefront of new technology for the communities it serves” said Dr. Oni-Orisan. 

DBS is an established treatment used in patients to alleviate symptoms such as tremor, slowness and abnormal muscle contractions. In appropriately selected patients with debilitating symptoms despite treatment with medications, the addition of DBS therapy can provide significant symptomatic relief.

"While DBS has been around for many years, the technology has evolved tremendously, significantly improving the lives of people living with Parkinson's disease," said Dr. Hiner. "The latest technology not only sends targeted signals to the area of the brain causing tremors, but it does it with such precision that it can be customized to meet the needs of each patient and fine-tuned as needed from a mobile device." 

DBS is a surgical procedure in which a lead is connected from the brain to a pacemaker-like battery pack implanted in the chest. DBS is not a cure for movement disorders, but it can dramatically decrease symptoms and improve patients' quality of life.
"Going into the procedure, I could have never imagined the vast improvement I experienced the moment the device was activated, states patient Laura Anter. "This procedure has given me back more control of my life."

Parkinson's disease is a neurological disorder characterized by tremors, slow movements, stiff muscles and gait problems that develop over time. Patients with essential tremors or Parkinson's disease with symptoms that are not optimally controlled by medications are good candidates for DBS surgery.
