CYBERONICS, INC. LEAD MODEL 302 Back to Search Results
Model Number 302-30
Event Date 11/01/2006
Event Type  Malfunction  
Event Description

It was reported that system diagnostic testing for a vns pt resulted in high impedance readings. The high impedance issue was discovered after the pt had been playing tennis. The pt also reported feeling neck pain on the left side with device stimulation after a tennis game. X-rays were taken and sent to mfr for review, and assessment of the x-rays revealed a gross lead fracture near the generator and another possible fracture between the negative and positive electrode. The pt's treating physician indicated that the observed lead discontinuities were likely related to stresses from the pt playing tennis. The pt may in the future be scheduled for revision surgery.

Event Description

On (b)(6) 2014, the patient reported that he could not receive an mri due to the broken lead in his neck. He stated that the break occurred sometime in 2007 or 2008 and he could not remember the details of the event. Although lead removal surgery is likely, it has not occurred to date.
