CYBERONICS - HOUSTON LEAD MODEL 302 Back to Search Results
Model Number 302-20
Device Problem Low impedance
Event Date 03/17/2010
Event Type  Malfunction  
Event Description

It was initially reported from social media post that a patient¿s son did not see any benefit from the vns device. At this point patient information was unknown. Additional information was received from the patient¿s mother which identified the patient whose vns was said to be ineffective. She said that the generator was dead and that vns had "failed" and did not help her son enough to agree to have the generator replaced. She said that the patient's physician had told her that explant would run the risk of infection and that it would be safer to keep the system implanted. The programming history database was reviewed and showed a possible short circuit condition. It appears that there was a dramatic drop in impedance from (b)(6) 2009 dcdc 2 to (b)(6) 2010 showing dcdc 0. Along with the allegation that the device was ineffective, this shows there may have been a short circuit condition present. No additional information has been received to date.
