CYBERONICS, INC. LEAD MODEL 304 Back to Search Results
Model Number 304-30
Event Date 11/23/2014
Event Type  Malfunction  
Event Description

Additional information was received that the patient's device diagnostics were checked on (b)(6) 2015 and that the results were within normal limits. It was also reported that the patient's pain was slightly better.

Event Description

It was reported that, for the past 1. 5 months, the patient has had random episodes of sudden discomfort from the generator site up to the left side of his neck that is progressively worsening and occurs 5 times per day. The nurse practitioner has adjusted vns but the discomfort doesn't seem to reduce and might not be associated with the stimulation. The patient experiences discomfort when he is lying still, sitting, or standing, doesn't seem to have any trigger. Patient was contacted several times to visit the clinic to adjust vns or disable vns if needed. But patient has not been able to visit due to transportation issues. Patient was last seen in (b)(6) 2014 and patient was set to comfortable settings at that time. No issues were reported with the device during this visit. Patient has been provided with medications for the pain meanwhile. X-rays were received with a note stating that the patient has been complaining of severe neck pain that radiates into his left clavicle. The pain was reported to be independent of vns activation and he does have pain when he turns his head. Per the nurse practitioner, there is a possible mircrofracture of the lead and the vns was disabled. The patient¿s next appointment is on (b)(6) 2015. The x-rays were reviewed and there did not appear to be any lead discontinuities in the portion of the lead that could be visualized. It was noted that the strain relief bend did not appear to be present. The lack of strain relief bend could possibly be a factor in the patient¿s pain. However no conclusions can be drawn regarding the exact cause of the pain. Attempts made for the diagnostic test results were unsuccessful to date.

Event Description

Additional information was received that the patient is still experiencing ¿pulling¿ sensation and discomfort in his left neck area. The device is currently off.

Manufacturer Narrative

Manufacturer reviewed x-rays of implanted device. X-rays reviewed by manufacturer, no gross lead discontinuities visualized.
