Reason for recall

Medtronic neurostimulators (used with pain and deep brain stimulation therapy) have a cycling feature that, when enabled, allows stimulation output to be toggled on and off based on the programmed settings. The use of this feature is determined by the physician and set using the clinician programmer. Current labeling indicates the use of cycling improves device longevity and recharge interval
