    Advice to Health Professionals to guide patients to follow the current instructions for recharging the RestoreSensor implantable neurostimulator, paying close attention to the Indicators of Charge Efficiency and Battery Charge Level in the charger. #### UPDATED ON 7/24/2017, the company submitted the field action completion report verifying the sending of the customer safety notice.
  • Causa
    Medtronic has confirmed four episodes of loss of therapy during the recharge of an implantable restoresensor neurostimulator with an incidence of 0.007% of the devices distributed worldwide. at conception, pacing therapy is discontinued when the battery voltage drops below 3.575 volts. in the reported occurrences, a charging session was terminated before reaching a recharge threshold of 3.615, which triggered a rapid state of battery depletion. as a result of the rapid state of battery discharge, the implanted neurostimulators ran out at 1,925 volts (a state of excessive discharge) in one or two days instead of the normal 30 days. the incorrect positioning (load efficiency) between the charger and the neurostimulator implanted during the recharge session proved to be an important factor in the reported events.
  • Acción
    Field Action is an Orientation for Health Professionals. Code: FA 709. Recommendations: Communicate patients to follow the current instructions for recharging the RestoreSensor implantable neurostimulator, paying close attention to the Indicators of Load Efficiency and Load Level the battery. • Check the charge level of the neurostimulator battery once a day or more often if necessary. • Keep the neurostimulator sufficiently charged to maintain therapy. It can be loaded at any time; it is not necessary to wait for the low battery message. • While recharging the neurostimulator, monitor the Charge Efficiency line and position the antenna to get as many solid black boxes as possible. If only two black boxes are filled (6 or more boxes are empty), reposition the antenna to improve signal strength between the neurostimulator and the charger. • During recharging, make sure the Neurostimulator Battery Charge Level is at least 25% before the end of the charging session. However, a full battery charge is ideal.

    “If our surveillance systems identify a potential performance issue, our personnel promptly evaluate the problem, including, when appropriate, conducting root cause investigations and internal testing to assess whether the product continues to meet specifications and defined performance criteria,” Medtronic told ICIJ in a statement. “In some cases, based on this evaluation, Medtronic may determine that a recall is necessary.” The company said that it communicates with healthcare providers and/or patients and provide recommendations to address such issues. Medtronic noted that these communications can include letters, emails, calls, press releases, physician notifications and social media postings, as well as informing the FDA and other regulators of the actions.
