Additional Manufacturer Narrative

DEVICE IS A VACUUM REGULATOR. THE DEVICE ACHIEVES ITS FUNCTION VIA A REGULATOR MODULE THAT IS EQUIPPED WITH A DIAPHRAGM. THE USER FILED A COMPLAINT THAT THE REGULATOR GAGE WAS JUMPY. DURING THE INVESTIGATION OF THE RETURNED DEVICES, IT WAS DISCOVERED THAT THE MALFUNCTIONING UNITS HAD THEIR DIAPHRAGM TORN. THE USER DID NOT REPORT ANY PT INVOLVEMENT NOR ANY ADVERSE EVENT. THE USER ALSO DID NOT FILE A FORM FDA-3500A. THE MFR IS FILING FORM FDA-3500A BECAUSE THIS WAS A MALFUNCTION THAT IF IT WERE TO RECUR, IT WOULD HAVE THE POTENTIAL TO CAUSE SOME PT HARM. INVESTIGATION INTO THE ROOT CAUSE IN ON-GOING AS OF THE DATE OF THIS REPORT AND IT HAS NOT YET BEEN DETERMINED THE EXTENT TO WHICH REMEDIAL ACTION WOULD BE APPROPRIATE TO PREVENT AN UNREASONABLE RISK OF SUBSTANTIAL HARM TO PUBLIC HEALTH.
