Manufacturer Narrative

The actual device was returned to the manufacturing facility for evaluation.Visual inspection revealed no anomalies in the appearance.The comparative pressure drop test was conducted as follows.The actual sample and a factory-retained sample with the involved lot number were circulated with saline solution while the pressure drop was determined.The actual sample was found to have a higher pressure drop, indicating that the actual sample had gotten clogged.The actual sample was fixed with glutaraldehyde solution and the housings were removed for further inspection of the inside.It was found that clots had formed both on the blood inlet side and on the blood outlet side.A larger amount of clots were found on the blood outlet side.The fiber was sliced in the longitudinal direction and its inside was inspected under electron microscope.It was found to have been clogged with the erythrocyte components, including echinocyte and white blood cells.A review of the device history record of the involved product code/lot # combination was conducted with no relevant findings.A search of the complaint file found one other report with the involved product code/lot# combination.See mdr number 9681834-2016-00079.There is no evidence that this event was related to a device defect or malfunction.Although the exact cause cannot be definitively determined based on the available information, it is likely that the dehydrating performance of the actual sample was deteriorated due to the fibers being clogged.The device labeling does address the potential for such an occurrence in the instruction for use (ifu) with the statement such as the following: "the capiox hemoconcentrator is designed to operate at flow rates within the range of 100 to 500ml/min during ultrafiltration.Do not use blood flow rates outside this range.Less than 100 ml/min blood flow may cause blood coagulation in the device." "do not exceed 50% hematocrit at the blood outlet during ultrafiltration." and "do not stop blood flow during extracorporeal circulation as it may cause clotting in the system.A blood flow of at least 50ml/min is recommended even if ultrafiltration is stopped by clamping the filtrate line." (b)(4).All available information has been placed on file in quality assurance at the manufacturing facility for appropriate tracking, trending and follow-up.

Event Description

The user facility reported a clog in the capiox device.Follow up communication with the user facility confirmed the following information: 5-6 hours after the extracorporeal circulation started the dehydrating performance of the actual sample became deteriorated; blood would not flow into the actual sample; and there was no harm to the patient.
