CYBERONICS, INC. LEAD MODEL 302 Back to Search Results
Model Number 302-20
Event Date 01/26/2015
Event Type  Malfunction  
Event Description

High impedance was observed during diagnostics tests performed around (b)(6) 2015. Patient also experienced increased seizure at that time. Patient underwent lead replacement on (b)(6) 2015 and the explanted lead was returned on (b)(6) 2015. During surgery, fibrosis was observed and was surgically removed in order for the new lead to be placed. Additional information was received that the high impedance was first noted on (b)(6) 2015 initially when the physician performed normal mode diagnostic test after increasing the output current to 0. 75 ma. The results indicated dcdc=7 and high lead impedance. Lead pin insertions issue was tested and was ruled out as the issue. Good diagnostics and normal impedance was observed for this patient after implant prior to high impedance. Patient's seizures was reported to have increased since (b)(6) 2015. The relation to pre-vns baseline is unknown at this time. Patient manipulation or trauma is not believed to have contributed to the high impedance. Analysis of the lead is underway but has not been completed.

Event Description

An analysis was performed on the returned lead portions. A portion of the lead was not returned to the manufacturer and therefore a complete evaluation could not be performed on the entire lead product. During the visual analysis of the lead, the quadfilar coil appeared to be broken at the proximal end of the anchor tether. Analysis of the quadfilar coil shows characteristics typical of a lead discontinuity which may include: material fracture, rough or pitted surface, thinned material thickness, electro-etching or material dissolution. An abraded opening was found on the outer silicone tubing. No other obvious anomalies were noted.

Manufacturer Narrative
