Medtronic, Inc. (NYSE: MDT) today announced the initiation of a prospective, multi-center, randomized U.S. clinical trial for the RestoreSensorTM neurostimulator that adapts therapy to the changing needs of chronic pain patients by responding automatically to changes in body position and activity in an upright position. The RestoreSensor neurostimulator received CE Mark approval in Europe and is under investigational use in the United States. The U.S. clinical trial will evaluate the benefits of the unique AdaptiveStimTM feature of the RestoreSensor device that uses a cutting-edge, proprietary smart technology for the first time in an implantable medical device for the treatment of chronic pain. Physicians at ten U.S. medical centers will be enrolling patients in this study. The first implant of a RestoreSensor neurostimulator in the study was performed by David Schultz, M.D., at MAPS Pain Clinic in Minneapolis.
“Neurostimulation offers patients a therapy that has been clinically proven to provide pain relief, but there is variance in the device settings required to maximize the pain relief and comfort based on a patient's activity”
"Neurostimulation offers patients a therapy that has been clinically proven to provide pain relief, but there is variance in the device settings required to maximize the pain relief and comfort based on a patient's activity," said David Schultz, M.D., founder and medical director of MAPS Pain Clinics and MAPS Applied Research Center (MARC) in Minneapolis, and investigator in the RestoreSensor clinical trial. "We are pleased to be involved in the clinical efforts to study a device that could address an unfulfilled need for a neurostimulation system. This device is designed to allow automatic response to changes in position and maintenance of a consistent, optimal level of stimulation for patients."
The level of stimulation required to manage a patient's pain at any given time is dependent on the distance between the spinal cord and implanted electrodes. However, this distance changes depending on whether the patient is upright or lying down in various positions. Currently, most patients have to use a remote control device to adjust the level of stimulation to maximize pain control and comfort after they change body positions. This often includes turning the stimulation up when a person is upright and active, or turning it down when they are lying down. The RestoreSensor device with AdaptiveStim technology is the first device to sense a change in body position and automatically optimize the pain therapy settings.
