Manufacturer Narrative

This follow-up report is submitted to fda in accord with applicable regulations.Upon further investigation of the reported event, the following information is new and/or changed: d4 (additional device information - added exp date).G4 (date received by manufacturer).G7 (indication that this is a follow-up report).H2 (follow-up due to additional information and device evaluation).H3 (device evaluated by manufacturer).H4 (device manufacture date).H6 (identification of evaluation codes 10, 11, 3331, 213, 67).Method code #1: 10 - actual device evaluated.Method code #2: 11 - testing of device from same lot/batch retained by manufacturer.Method code #3: 3331 - analysis of production records.Results code: 213 - no device problem found.Conclusions code: 67 - no problem detected.The returned sample was visually inspected.It was noted to contain dried blood within the threads of the large bore cap.The returned sample was then leak tested (as received) by connecting with the calibrated manometer, submerged into a water bath, and pressurized up to 1030 mmhg.A leak was noted from the large bore adaptor at approximately 90 mmhg.The large blue cap was then loosened and retightened by hand.The unit was then pressurized with air, submerged in a water bath, and observed for any leaks.A leak was noted again from the large blue luer cap at approximately 200 mmhg.The shunt sensor was then soaked in di water.After loosening and re-tightening the blue large bore adapter a second time (removing/loosening dried blood residue), the sample was leak tested again by connecting with the calibrated manometer, submerged into a water bath, and pressurized up to 1030 mmhg, and no leaks were noted.The second leak was most likely attributed to dried blood within the threads of the sensor connections that was not fully removed during decontamination.A retention sample from the same lot number was visually inspected and confirmed to have no traces of buffer on the outside of the unit or inside the pouch.The retention sample was then pressurized with air up to 1030 mmhg, submerged in a water bath, and observed for any leaks.No leaks were noted on the retention sample.The root cause for this event was determined to be the large blue vent cap for shunt sensor was not fully tightened either during setup of the circuit, or after the gas calibration.When the large blue vent cap was loosened, it had not been re-tightened fully prior to use in the line, causing a leak from the cap.All available information has been placed on file in quality management for appropriate tracking, trending, and follow-up.
