(b)(4).The customer returned one, 3-lumen hemodialysis catheter for analysis.Signs of use in the form of biological material were observed within the catheter body.Visual inspection did not reveal any defects or anomalies.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)".All three lumens were flushed using a lab inventory syringe, and all lumen flushed as intended.No signs of a blockage or leaking were observed.The returned catheter was then tested per bs en iso 10555-1 section 4.7.1 (amrq-000162), 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 a 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.Therefore, the sample passed functional testing.A manual tug test confirmed all extension lines were fully secured within their respective 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 customer report of a blocked catheter was not confirmed through complaint investigation of the returned sample.No defects or anomalies were observed on the returned sample.The catheter met all relevant dimensional and functional requirements including patency test and leak testing performed per iso 10555-1.A device history record review was performed, and no relevant findings were identified.Based on the customer report and sample received, no problem was found with the returned device.Teleflex will continue to monitor and trend on reports of this nature.
