Event Date 01/02/2019

Event Type  malfunction  

Manufacturer Narrative

Terumo has not received the device for evaluation; therefore, the investigation has yet to be completed.Terumo plans on submitting a follow-up report when the investigation is complete and when more information becomes available.(b)(4).

Event Description

The user facility reported to terumo cardiovascular that prior to cardiopulmonary bypass during prime, leakage was observed from the shunt sensor.No patient involvement.Product was changed out.Procedure was completed successfully.

Manufacturer Narrative

This follow-up report is submitted to fda in accord with applicable regulations ¿ and as indicated by terumo cardiovascular systems in the initial report submitted to the fda on january 30, 2019.Upon further investigation of the reported event, the following information is new and/or changed: d4 (additional device information - added exp date).D10 (device availability).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 - testing of actual/suspected device.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 buffer 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 130 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 330 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 buffer 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 buffer within the threads of the sensor connections.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.
