Event Description

During review of the in-house programming/diagnostic history database, it was observed that high impedance was observed on (b)(6) 2012. It is unknown if any patient manipulation or trauma occurred that could have caused or contributed to the high impedance reading. It is unknown if surgery has been performed. The device was not programmed off after observing the high impedance reading. Attempts to obtain additional information have been unsuccessful to date.

Event Description

Additional information was received stating that the vns patient¿s device was tested and diagnostic results showed high impedance. X-rays were taken and were reported by the physician to be unremarkable. The patient underwent surgery on (b)(6) 2014. Upon opening the neck incision site, an abundant amount of fibrosis was observed and the surgeon determined that surgery could not continue so the patient was closed. No known surgical interventions to resolve the reported high impedance have occurred to date.
