The office did state that the pt was seen on (b)(6) 2011 and the vns was working properly at that time. In addition, the pt refused to have the vns disabled. It is unk which physician the pt may be seeing at present.

Manufacturer Narrative

The event of the patient's worsening asthma was inadvertently omitted from the initial mdr report.

Event Description

Clinic notes from the new treating physician were received indicating surgery to replace the vns generator and possibly the lead may be done in order to relieve the patient's symptoms of voice alteration, dyspnea and painful stimulation. It is suspected the lead placement may be the cause of the patient's adverse events. A surgery date has not been set. Attempts for additional information are in progress.
