Event Description

It was reported by a nurse that a vns patient reported buzzing and pain in the top of his head that had occurred 3 times within the last 3 weeks of initial report. The patient reported that placing the magnet on the generator ameliorated the pain. Moreover, the patient indicated the pain was not occurring with normal stimulation and no patient manipulation or trauma was reported. The nurse further stated that a generator diagnostic tests was performed and received a low impedance warning. The patient was interrogated and the device was found to be at 0 ma. The patient was re-programmed to 1. 5/25/500/30/1. 1 then performed system diagnostics which resulted within normal limits (ok/ok/1/no). Further information from the treating nurse indicated that the patient was scheduled for complete replacement. Moreover information from a company representative indicated the patient underwent surgery as scheduled. Good faith attempts to obtain the explanted devices have been unsuccessful to date. Additional information was received from the treating neurologist indicating the cause of the buzzing was related to generator with/ or wire malfunction. Moreover, the replacement surgery was done for patient comfort according to the neurologist.
