MINNEAPOLIS--(BUSINESS WIRE)--Nov. 17, 2011-- Medtronic, Inc. (NYSE: MDT) today announced the U.S. Food & Drug Administration (FDA) approval of its AdaptiveStim™ with RestoreSensor™...
“Medtronic is pleased to introduce AdaptiveStim technology, and we look forward to helping address the many concerns we’ve heard from physicians and patients about traditional neurostimulation systems,” said
Neurostimulation systems consist of an implantable medical device similar to a pacemaker to interrupt pain signals from reaching the brain. The treatment has become a mainstay of chronic pain management; however, a change in body position (e.g., sitting up or lying down) can result in an increase or decrease in the intensity of stimulation as a patient’s spinal cord moves closer or further away from the stimulation site. As a result, patients may need to make frequent manual adjustments to their stimulation levels as they move, using a handheld patient programmer.
AdaptiveStim with RestoreSensor reduces the need for manual programming changes by automatically adapting stimulation levels to the needs of people with chronic back and/or leg pain by recognizing and remembering the correlation between a change in body position and the level of stimulation needed. It also records and stores the frequency of posture changes, providing objective feedback to clinicians to help them understand how a patient’s individual stimulation requirements are changing over time. Additionally, AdaptiveStim with RestoreSensor is approved by the
Data from the U.S. RestoreSensor clinical trial demonstrate that the AdaptiveStim with RestoreSensor neurostimulator provides effective pain relief and convenience. At the end of the study, 86.5 percent of study participants with chronic pain, who were included in an intent-to-treat analysis (n=74), experienced somewhat better or much better pain relief with no loss of convenience, or somewhat more or much more convenience with no loss of pain relief, when the device’s AdaptiveStim technology was turned on, compared to a control period when the participants manually adjusted neurostimulation settings using a patient programmer. With AdaptiveStim, study participants reported functional improvements, including improved comfort during position changes (80.3 percent).
The multicenter, prospective, open-label, randomized, crossover study enrolled 79 study participants at 10 U.S. centers. Participants were randomized to receive either stimulation from the RestoreSensor device for six weeks with the AdaptiveStim technology turned on followed by six weeks with AdaptiveStim turned off, or six weeks with AdaptiveStim turned off followed by six weeks with AdaptiveStim turned on. When AdaptiveStim was turned off, participants manually adjusted stimulation levels using a patient programmer.
“This research provides important clinical evidence that demonstrates this innovative, position-sensing technology improves pain management and makes it easier for patients suffering from chronic pain to better manage their symptoms when compared to systems that require manual changes in stimulation,” said
The profile of adverse events reported during the U.S. clinical trial was similar with and without the AdaptiveStim technology activated.

About Chronic Pain
Chronic pain affects an estimated 116 million American adults – more than the total affected by heart disease, cancer, and diabetes combined2. Chronic pain, which is defined as pain that lasts for more than three to six months, is a disabling condition, not simply a symptom of another disease or condition, and it can be either intermittent or continuous. For some, chronic pain is so severe that it interferes with working, eating, participating in physical activity and enjoying life3.
