Model Number 102
Event Date 01/31/2010
Event Type  Malfunction  
Event Description

It was reported that the pt was seen for a follow up appointment due to sudden neck pain, which the pt felt was related to the vns device. In addition, the pt had been sick over the previous weekend with vomiting, and the neck pain worsened. The pt had secured the magnet over the generator site to temporarily disable stimulation until the appointment. At the follow up appointment, a system diagnostic test was performed which revealed high lead impedance. The pt subsequently had surgery where only the generator was replaced. Further follow up with the surgeon revealed that the high lead impedance resolved when a new generator was connected to the existing lead. Good faith attempts to obtain additional information are underway. The explanted generator has been returned to manufacturer where analysis is underway.
