Manufacturer Narrative

Additional information: a3, g1 (second address).Corrected information: d9, g1, h3, h6.Device was returned for additional evaluation and investigation.A review of the device history record, which includes verification of all steps in the manufacturing of the pump, verification of all final testing performed by/on the pump, verification of sterilization, and packaging for subject pump was performed.The review did not identify any nonconformances, issues or capas associated with pump function.Additional physical investigation was performed on the device, confirming the alleged issue.Operation of the pump reservoir function was checked by filling the reservoir with 20 ml of sterile water for injection (swi) and allowing the reservoir's pressure to return the fluid into the syringe.The reservoir was refilled and the cap was flushed with 5 ml of swi.A demand bolus of 0.300 mg with a 1.00 mg/ml concentration over 16 minutes was programmed with a programmer.The pump successfully primed.The pump was programmed with a 1.994 mg daily dose multirate flow test over a 24-hour time period at 37°c for 1 day.The dispensed volume was 0 ml (0%) of the expected volume.The catheter access port and suture ring were removed and the pump was decontaminated a second time.The top cover of the pump was machined off and the valves' "pull open / hold open" currents were measured.The results confirmed that the inlet current required a higher current to pull open than the specification, and the outlet valve failed to produce a readable current signal to measure.This indicates that current needed to pull open far exceeds the design specification for the valve.The cause of the issue was confirmed.The pump failed to flow to specification with both the inlet and outlet valves requiring a higher pull open current than the designed specification.Internal complaint number: (b)(4).
