Brain Stimulation System Treats Tremor Patients

The system impulse generator (IPG) possesses a gentle, contoured oval shape with a small footprint of just 20 cm2. The IPG is accompanied by a multilumen lead that includes 8 contacts and a broad span. Targeting is achieved using a multiple independent current control (MICC) platform, which allows selective control of the electric current delivered through each individual electrode.

Unique rechargeable battery technology proffers the system with a 25 year life span, helping to reduce surgical interventions; and zero Volt battery technology ensures that even if the battery is completely discharged, there will be no failure or damage. The charging system, as is the remote control, are completely cordless, allowing patients to remain active. The Vercise DBS system is a product of Boston Scientific (Natick, MA, USA), and has received the European Community CE marking of approval.

“With the launch of the Vercise DBS System for the treatment of patients with Parkinson's disease in 2012, for dystonia in 2013, and now for tremor, Boston Scientific continues to demonstrate its commitment to provide more access to DBS therapy to more patients,” said Maulik Nanavaty, president of neuromodulation at Boston Scientific. “We believe this advanced technology can play a critical role in improving the lives of patients who suffer from these devastating conditions.”

“Essential tremor can be very debilitating for patients in their day-to-day activities such as writing and eating,” said Prof. Veerle Visser Vandewalle, MD, of University Hospital Cologne (Germany), who implanted the first European system. “The Vercise DBS System provides advanced tremor care through precise neural targeting that is designed to manage ET symptoms effectively and improve patient quality of life.”

ET is a neurological disorder that causes a rhythmic shaking, and can affect almost any part of the body, but occurs most often in the hands, especially when intent is present, such as drinking from a glass, holding a fork, writing, or shaving. Although not a dangerous condition, ET worsens over time. It can occur at any age, but is most common in people age 40 and older.
