The quality records for the lot 138689 000 are complete and in order.No non-conformity was recorded for this lot number.No similar complaint has been recorded for this lot of xcela power injectable port.No deviation has been recorded in material and/or manufacturing process during manufacturing of the lot number 138689 000 of xcela power injectable port.The correct fluid pathway of every port, as well as leakage is tested during production at 100% for the dual port (according control instruction (b)(4)).And we verify unit by unit that nothing is blocking the lumen of the port pin under (according work instruction (b)(4)) no similar complaint has been reported on the last three years for xcela dual lumen port.On other type of ports, single lumen, we recorded two similar complaint: (b)(4), us market (pfm inc reference (b)(4)), article h965451030, (b)(4), european market, titanium port; it is a problem with a low recurrence rate, there is no possible link between the products of the complaints listed above, and the product of this complaint (b)(4).N.B: we recorded cases of blocked ports which cannot be injected, but only after several days/weeks/months/years of implantation, not during preparation for port insertion.Blockage caused by blood clots, drug precipitation, thrombosis, catheter flap or pinch-off.Hypothesis: three possible causes of the reported problem: the needle was not inserted entirely & consequently the bevel was inside the septum.This is very unlikely as the port is outside of the patient.The pressure to push the fluid was superior to the force they applied on the syringe pump, so, there is obstruction inside the port.It could be possible that the huber needle used was itself blocked.Conclusion: the review of the device history records, the review of similar complaints and risk management review showed no deviation.No deviation has been recorded in material and/or manufacturing process during manufacturing of the lot number 138689000 of xcela power injectable port.Without the returned product, we are not able to further the investigation.
