Additional Manufacturer Narrative

ADDITIONAL INFORMATION PROVIDED IN D.9., H.3., H.6. AND H.11. THE RETURNED PRODUCT WAS VISUALLY INSPECTED AND NO OBVIOUS DEFECTS WERE OBSERVED. A CALIBRATED CONSOLE WAS USED TO TEST THE SAMPLE. THE CONSOLES COULD RECOGNIZE THE VISCUS FLUID CONTROL (VFC) BY ILLUMINATING GREEN ON THE LIGHT EMITTING DIODE (LED) RING. THE VFC SAMPLE WAS FILLED WITH SILICONE OIL PER DIRECTIONS FOR USE (DFU); IN INJECTION MODE THE PLUNGER MOVED FREELY AND MET SPECIFICATIONS. EXTRACTION MODE WAS THEN SELECTED AND THE VFC COULD ASPIRATE SILICONE OIL INTO THE BARREL OF THE SYRINGE; NO ANOMALIES WERE OBSERVED DURING THIS STEP. PRESSURE WAS STABLE DURING FUNCTIONAL TESTING. THE PLUNGER IN THE SYRINGE MOVED SMOOTHLY DURING OPERATION. ADDITIONALLY, ALL CONNECTIONS WERE FOUND TO FIT SECURELY. NO TUBING AIR LEAK WAS OBSERVED. THE INVESTIGATION CONDUCTED A NON-CONFORMANCE REVIEW OF THE REPORTED LOT NUMBER. NO DEVIATION WERE IDENTIFIED THAT WOULD HAVE CONTRIBUTED TO THIS EVENT AND ALL CORRESPONDING PRODUCTION RELEASE SPECIFICATIONS DEFINED IN THE DEVICE MASTER RECORD WERE MET.
