Event Description

Notes dated (b)(6) 2016 state that the patient's battery is reported to be near end of service and requires replacement. Notes dated (b)(6) 2016 state that one week prior the patient had onset of shooting pain in her left axilla. The notes state that the patient was seen urgently by the neurosurgeon upon complaints of pain/discomfort of concern for vns malfunctioning. Noted to have protruding piece of chest wall tissue of concern for a surgical clip vs wire/generator attachment. Vns was interrogated and found to have normal impedance. Chest wall protrusion of concern for adhesions that may be contributing to muscular skeletal discomfort. The vns was turned off for 20-30 minutes and then turned back on, patient was observed during this time for side effects/adverse effects and no discomfort was noted. It was indicated that on (b)(6) 2016 the patient had surgery. The generator was not changed but it was indicated that something was done to the leads although it is not clear at this time what they did. Post-op impedance was still within normal limits.

Manufacturer Narrative

Information received the day the initial mdr was submitted was inadvertently omitted from the initial mdr.

Event Description

The patient was set to have surgery but it was determined that no replacement of the generator was necessary. The leads were manipulated and it was stated that the device seems to be ok. Clarification from the nurse was obtained which showed that the reason for the planned replacement was solely for the patient's neck pain. There was no chest pain, only pain in the neck area of the vns. She confirmed the battery was still good and impedance levels were fine. The surgeon also took some x-rays and determined the positioning of the tie-down (or what they called the elastic flange) was likely causing her discomfort against the skin. She stated that they dissected the flange out and because there was enough scarring around the lead they did not need to secure it again. The procedure was for patient comfort.
