The LivaNova VNS Therapy System, used for Vagus Nerve Stimulation (VNS), consists of an implantable VNS Therapy generator, lead, and external programming system used to change stimulation settings. The generator is an implantable, multi-programmable pulse generator that delivers electrical signal...
Official recall recorded by the U.S. Food & Drug Administration.
The hazard
Lead impedance values reported by the affected VNS generator will be higher compared to those reported by previous models. This is due to a change in the timing of when affected VNS generator takes the lead impedance measurement during diagnostic testing. As a result, normal impedance ranges for the affected VNS generator have shifted relative to the existing thresholds of 600 - 5300 Ohms defined in labeling and as present in the programming software.
