Manufacturer Narrative

Implanted date: device was not implanted.Explanted date: device was not explanted.The actual device has been returned for evaluation.The investigation is currently ongoing.A follow up report will be submitted once the investigation is complete.A review of the device history record and the shipping inspection record from the reported product code/lot number combination was conducted with no findings.(b)(4).

Event Description

The user facility reported that the involved capiox hemoconcentrator was stuck and there was no function during bypass after 4hrs.They changed to a new one to allow the procedure keep going until the end.The patient impact and procedure outcome was reported to be unknown.

Manufacturer Narrative

The actual device was received for evaluation.Visual inspection revealed no obvious anomalies.The actual sample was rinsed, and was visually inspected closer, and was confirmed to not have any anomaly, such as a break, which could have led to clogging the fibers.The actual sample was built into a circuit with tubes.With a help of a roller pump, bovine blood at ht25% and 37oc was let to flow through the circuit.With the generation of no clogging in the fiber, the normal flow of bovine blood was observed.The actual sample was tested for its ultrafiltration performance.The obtained result was confirmed to meet the specifications.The pressure loss was determined during the circulation at the flow rate of 500ml/min.And tmp400mmhg.The obtained result was confirmed to meet the specifications.Ifu states: adequate heparinization of the blood is required in order to prevent it from clotting in the system.(precautions) the capiox hemoconcentrator is designed to operate at flow rates within the range of 100 to 500 ml/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.Do not stop blood flow during extracorporeal circulation as it may cause clotting in the system.A blood flow of least 50 ml/min is recommended even if ultrafiltration is stopped by clamping the filtrate line.Bubbles in the system may cause clotting and blood damage.Based on the provided information and investigation results, there is no definitive evidence that this event was related to a device defect or malfunction.The investigation results verified the returned sample was of the normal product.Based on the provided information, it is likely that the actual sample had been clogged due to the decreased rate of the flow going into the actual sample, causing the blood to become concentrated excessively and plug the fibers; or the blood which had become high in concentration due to the administration of packed red blood cells; or due to removal of water contained in the blood, entered the actual sample and became further concentrated and plugged the fibers.However, the exact cause of the reported event cannot be definitively determined based on the available information.
