H10: the actual devices were not returned for evaluation however three companion samples were provided.The visual inspection showed no defect on the sets (no damage or disconnected component).All connectors were correctly screwed and no issue was observed on these companion samples.Based on the information provided by the customer, the customer didn't remove the y priming accessory at the end of the priming, and left it connected between the patient catheter and the luer lock of the access line.This is a misuse of the product.Based on the additional information provided by the customer, the customer didn't remove the y priming accessory at the end of the priming, and leave it connected between the patient catheter and the luer lock of the access line (misuse of the product).The access line of the set must be directly connected to the patient catheter (i.E.Without any device between the access line and the catheter) via the male luer connector of the access line.The use of additional devices, such as three-way valves, stopcocks, y priming accessory during treatment or extension lines, may impair pressure monitoring.Per the instruction in the prismaflex graphical user interphase (gui), the y-line/connector used for priming of the prismaflex set must be removed prior to connecting the patient; the access and return lines are to be connected directly to the catheter.Thus, the use of the y-connector during treatment is considered use error.A batch review was conducted and there were no deviations found related to this reported condition during the manufacture of this lot.Should additional relevant information become available, a supplemental report will be submitted.
