CYBERONICS - HOUSTON LEAD MODEL 303 Back to Search Results
Model Number 303-30
Event Date 07/29/2015
Event Type  Malfunction  
Event Description

It was reported on (b)(6) 2015 that a low impedance warning message was seen on a patient's device upon interrogation. This was the patient's first appointment after battery replacement on (b)(6) 2015. It was noted that after the replacement, diagnostics were taken and came back in range. It was then noted that following a running of the system diagnostics the impedance resulted in range, 1692 ohms. The decoder information from generator was received and indicated that the impedance values were fluctuating from normal impedance values back to low impedance values and then back to normal impedance. Based on these impedance values it is clear that there is a short in the circuit causing the impedance to fluctuate between normal and low readings. This is likely due to wear on the lead based on the age of the device. While surgical intervention is likely, no surgery has been planned or scheduled to date.
