Additional Manufacturer Narrative
The unintended stimulation/new pain questionnaire was reviewed.However, the questionnaire was completed with limited information.Potential causes of shock include: programming parameters, migration, interference from a non-curonix device, the patient having contraindicating conditions, severe force applied to the implant (patient fall, accidents), and the device being used off-label.The stimulator is used to treat pain.The cause of the reported issue is unknown.The investigation findings do not lead to a clear conclusion about the cause of the reported issue.Therefore, the conclusion has been selected as unable to determine the root cause.Rates reviewed at the most recent complaint trending meeting do not indicate a significant increase in unintended stimulation/new pain issues.Unintended stimulation/new pain issue rates remain acceptably low; thus, a capa is not required.Unintended stimulation/new pain issues rates will continue to be tracked and trended.
