Manufacturer Narrative

Event Description

Clinic notes were received which indicated that a patient was having difficulty breathing. The patient had been evaluated by a pulmonologist and an ear, nose, and throat (ent) physician who were unable to determine the cause of the breathing difficulties. The ent observed paradoxical vocal cord movement. Vns function was noted to be normal with normal diagnostics. Device settings were adjusted to try to alleviate the breathing problems but were unsuccessful. The patient's breathing problems were alleviated by disabling vns therapy. It is noted that the patient's generator and lead are both implanted on the right side following a high impedance observation on a prior lead implanted on the left side (reported in mfg. Report #: 1644487-2014-00786). The providers are considering moving the system back to the left side but no known surgical interventions have occurred to date. Attempts for additional relevant information have been unsuccessful to date.

Event Description

The provider reported that the patient's breathing difficulties started in (b)(6) 2014, at approximately the 3rd clinic visit after implant. The provider stated he did not know the cause of the paradoxical vocal cord movement.

Event Description

Information was received indicating that since the time of vns disablement the patient¿s breathing has improved and the patient has had 2 seizures. The patient underwent full system revision which moved the vns system back over to the patient¿s left side. The reason for explant was stated to be coughing which caused pain for the patient. The lead on the right side was not explanted.

Manufacturer Narrative

Supplemental report #2 should have stated that the reason for system revision, and not suspect device explant, was due to coughing which caused pain for the patient. Supplemental report #2 inadvertently indicated an explant date of (b)(6) 2015, however, the suspect device was not explanted.

Event Description
