Qn#(b)(4).The customer returned one single lumen midline catheter for evaluation.The sample contained obvious signs of use in the form of biological material in the extension line and on the catheter body.Visual inspection revealed a small hole in the distal extension line adjacent to the luer hub.The damage is consistent with a molding issue.The total length of the catheter body was measured to be 6.625" which is within specifications of 6.25"-6.75" per coated catheter product drawing.The outer diameter of the distal lumen measured to be 0.09535" which is within specifications of 0.093"-0.097" per distal extension line extrusion product drawing.The inner diameter of the distal extension line measured to be 0.057", which is within specifications of 0.055"-0.059" per distal extension line extrusion product drawing.This indicates that the wall thickness measured as expected.The catheter was flushed using a lab inventory syringe to ensure there were no blockages.The distal end was then clamped, and a water-filled lab inventory syringe pressurized the distal line.A leak was observed near the luer hub when pressurized.A manual tug test confirmed the distal extension line was fully secured within the luer hub.A device history record review was performed, and no relevant findings were identified.The ifu provided with this kit warns the user, "do not secure, staple, and/or suture directly to outside diameter of catheter body or extension lines to reduce risk of cutting or damaging the catheter or impeding catheter flow.Secure only at indicated stabilization locations.Open slide clamp prior to infusion through lumen to reduce risk of damage to extension line from excessive pressure." the customer report of an extension line leak was confirmed through complaint investigation of the returned sample.The distal extension line contained one hole/separation adjacent to the luer hub.The appearance of the damage was consistent with a manufacturing related root cause.A non-conformance has been initiated to further investigate this molding issue.Teleflex will continue to monitor and trend for complaints of this nature.
