Event Description

Further investigation revealed that the patient's generator and lead were explanted on (b)(6) 2013.

Event Description

It was reported on 06/22/2015 that this patient, who had his device explanted in 2013, went to the er and the xray showed a "square piece of metal" under the skin. The patient was under the impression that the entire device was explanted. It is unknown at this time of the piece of metal found was left over from the vns explant surgery or is unrelated. Attempts for additional relevant information have been unsuccessful to date.

Event Description

It was reported that the patient cut himself of the neck area (near the electrodes) while shaving a few weeks prior and that he has now developed an infection at the site. It was reported that the patient has a thin frame and that the electrodes are visible through the wound. It was reported that the wound was full of pus and was "looking bad". The surgeon prescribed antibiotics and has scheduled the patient for explant. The surgery was scheduled; however, no information has been received that the explant has occurred as scheduled.

Manufacturer Narrative

Device manufacturing records were reviewed. Review of manufacturing records confirmed sterilization for both the generator and lead prior to distribution.

Event Description

Patient will undergo exploratory surgery on (b)(6) 2015 to try to remove the object that is in his neck. The surgeon plans to remove the object and will not remove it if it is affecting a vein. No additional information has been received after the exploratory surgery.
