Event Type  Malfunction  
Event Description

On (b)(6) 2013, an image of a patient¿s neck/chest area was provided where it appeared that the generator was sideways and protruding. Follow-up showed that the patient was implanted on (b)(6) 2013. The patient was seen on (b)(6) 2013 and reported that the device had been the way it was for a couple of weeks. Thee surgeon manipulated the device with some improvement of the protrusion. The patient was advised to continue to observe, but no intervention was recommended. There was no reported patient manipulation, trauma, or physiological changes that may have caused/contributed to the event. Follow-up with the surgeon showed that there was slight protrusion/flipping of the patient¿s generator. Clinic notes dated (b)(6) 2103 indicated that the patient had pain at the generator site when lying prone and on her side. The generator was mildly painful to palpitation. The device appeared rotated within the surgical pocket and was protruding beneath the skin. The device had not been programmed on. Clinic noted dated (b)(6) 2013 indicated that the patient returned for titration. The patient had continued pain at the generator site when lying prone or on her side. The device was interrogated: 0. 50/30/500/30/5/0. 75/60/500. The patient¿s pain would continue to be observed. Clinic notes dated (b)(6) 2013 indicated that the patient continued to have discomfort intermittently with stimulation, particularly when lying down at night. A system diagnostic was performed with results of 3282 ohms. The patient was unable to tolerate an increase in output current, so stimulation was returned to the previous settings. Device settings were provided: 0. 50/30/500/30/5/0. 75/60/500. A revision referral indicated that the patient was to be revised due to discomfort and slightly elevated lead impedance. Follow-up showed that the referral was for patient comfort. On (b)(6) 2013, the patient underwent lead revision. At the time of surgery, fluid was seen in the outer tubing. The generator was briefly soaking in betadine. It was also noted that the lead was placed on the wrong nerve (anysa) by the previous surgeon. The new surgeon fixed the issue and notified the neurologist. The implant card indicated that the replacement was due to an "adverse event" and "malfunction". No other information has been provided.
