Medtronic Activa RC (37612), Activa PC (37601), Activa SC (37602), Activa SC (37603), Activa PC+S (37604), Multi-program Rechargeable Neurostimulator for Deep Brain Stimulation for movement disorders.

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

Medtronic sent a Medical Device Correction letter dated February 2014 to all affected consignees. The letter identified the product, the problem, and the action to be taken by the consignee. Consignees were instructed to do the following: If you have patients with cycling enabled or wish to use cycling, use the updated calculations and graphs available online at professional.medtronic.com/cycling to assess the impact of cycling on device longevity. Medtronic will update the product labeling in the second half of 2014. " Remind your patients to continue to check their battery status. Instructions on how to check battery status can be found in the patient programmer or recharger system manual. " Pain Stimulation Trialing Only: The cycling feature should not be enabled on the External Neurostimulator (ENS) when estimating device longevity because the resulting longevity estimate for non-rechargeable devices may not provide accurate information. Consignees were also instructed to acknowledge receipt of the notice by completing the attached reply form and returning it to Medtronic using the contact details on the reply form. For questions consignees can contact Medtronic Neuromodulation Technical services at 1-800-707-0933 weekdays 7am - 6pm CST. For questions regarding this recall call 800-707-0933.
