Qn# (b)(4).Section d.4.-udi# corrected to (b)(4).The customer returned one 2-lumen 4 fr × 5 cm catheter for analysis.Signs of use were observed on the extension lines and the juncture hub.Initial visual examination of the catheter did not identify any defects or anomalies.The catheter was functionally tested and performed as intended, with no issues observed during testing.The catheter body length measured 52 mm, which is within the specification limits of 45.2mm -55.6mm per catheter product drawing.The catheter body outer diameter measured 0.055", which is within the specification limits of 0.054" - 0.058" per catheter extrusion product drawing.The catheter was functionally tested per the instructions for use (ifu).The ifu provided with this kit instructs the user, "flush each lumen with sterile normal saline for injection to establish patency and prime lumen(s)".No leaking or blockages were observed when all two lumens were flushed.The returned catheter was then tested per bs en iso 10555-1 section 4.7.1 (amrq-000071 rev.17) which states that there shall be no liquid leakage in the form of one or more falling drops when pressurized to 300 kpa for 30 seconds.The device was connected to lab leak tester and pressurized to 300 kpa for 30 seconds with the distal end occluded.The extension lines were connected individually to the leak tester, and when pressurized, no catheter backflow or leaks were detected from any portion of the catheter, which indicates no inter-lumen crossover was observed.Based on this testing, the customer issue could not be reproduced with the returned sample.A manual tug test confirmed that the extension lines were secure within their respective luer hubs.A device history record review was performed, and no relevant findings were identified.The ifu provided with the kit informs 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." the report of a leaking catheter body was not confirmed through investigation of the returned sample.Visual examination did not ide ntify any defects or anomalies.All lumens passed functional leak testing performed per iso 10555-1 and no evidence of leakage, backflow, or inter-lumen crossover was observed with any of the lumens.A device history record review was performed, and no relevant findings were identified.Based on the customer report and functional testing of the sample received, no problem was found with the returned device.Teleflex will continue to monitor and trend for reports of this nature.
