CYBERONICS, INC. LEAD MODEL 304-20 Back to Search Results
Model Number 304-20
Event Date 06/01/2014
Event Type  Injury  
Event Description

During an appointment on (b)(6) 2014, the patient reported that there is a "problem with the lead" that started approximately two weeks prior. She could feel pain in ear and at the clavicle area with stimulation, but it was unclear whether it was with every stimulation on-time; however, the patient noted she could feel the stimulation on-times normally. There was no known preceding trauma, but does have a (b)(6) old and has gained weight recent. Diagnostics indicated an impedance of 2040 ohms which was within normal limits. The vns output current was lowered to 1. 25ma, which lessened the pain by the patient. Lead revision was going to be considered. Additional information was later received on 08/13/2015 indicating that the patient s device was turned off with only the magnet still on. The patient was referred for vns replacement surgery. It was noted that the patient previously wanted the device explanted, but the physician persuaded her to keep it. During system diagnostics, the patient reported pain again. No surgical intervention has occurred to date.

Event Description

The patient later had lead replacement surgery. Pre-operatively, lead impedance was reported to be okay. The surgeon opted to not replace the generator, as he was not sure based on her previous tolerability whether putting in another brand new generator was appropriate. The explant hospital will not return explanted products per hospital policy, so analysis is unable to be performed. No additional relevant information has been received to date.
