Continuation of d11: iv antibiotics.(b)(4).The customer returned one 4-lumen catheter for investigation.Visual examination revealed no obvious defects or anomalies.The total length of the returned catheter body measured to be 169 mm which is within specifications of 157-177 mm per product drawing.Functional inspection was performed per the instructions-for-use (ifu) provided with this kit.The ifu states, "flush each lumen with sterile normal saline for injection to establish patency and prime lumen(s)." all three lumens were flushed using a water-filled lab inventory syringe.No leaks or blockages were detected.When each lumen was flushed, water exited the respective skive location.No issues were detected.The distal tip of the catheter was then clamped.A lab inventory syringe was used to pressurize each lumen.No backflow was observed in any of the extension lines.A lab inventory guide wire (of the same size as the guide wire provided with this kit) was advanced through the distal lumen and exited through the distal tip.No issues were identified.The customer did not provide a lot number; therefore, a device history record review was performed based upon a lot number from the sales history data of the customer.No relevant findings were identified.The instructions for use (ifu) provided with this kit warns the user, "using catheters not indicated for high pressure injection for such applications can result in inter-lumen crossover or rupture with potential for injury." the customer report of inter lumen crossover could not be confirmed through functional testing of the returned sample.The catheter passed all relevant visual, dimensional, and functional testing, and a device history record review was performed on a potential lot (identified from a sales history review for this customer) and no relevant findings were identified.No problem was found with the returned sample.Teleflex will continue to monitor and trend for complaints of this nature.
