Qn# (b)(4).The customer returned one connector assembly with "arrow vectorflow" printed on the juncture hub.The catheter was not returned by the customer.The connector assembly showed evidence of use.The customer returned a photo of the catheter in the patient.In the photo, the catheter appears to be leaking blood near the juncture hub; however, the exact location of the leak is unclear.Visual inspection with and without magnification did not reveal and defects or anomalies.Because the catheter in question was not returned with the assembly, a lab catheter was used for testing according to chronic hemodialysis catheter module requirements which is based on bs en iso 10555-1, 4.7.1.The venous and arterial extension lines were pressurized with water to 45psi for 30 seconds with the venous and arterial tips occluded.No leaks were observed from either extension lines.A device history record review was performed on the catheter and no relevant findings were found to suggest a manufacturing issue.The product ifu describes the technique for seating the hub connection assembly into the catheter body.The ifu cautions the user, "ensure compression sleeve is securely positioned inside threaded compression cap.Avoid attempts to place compression sleeve onto hub connection assembly cannula and then apply threaded compression cap.Incomplete compression may occur causing catheter separation." the ifu also notes, "green compression sleeve must be present when threading compression cap onto hub connection assembly.Failure to do so may result in air embolism, blood loss, or catheter separation." complaint verification testing could not be performed as the catheter was not returned for analysis.While performing a leak test on the returned connector assembly and lab catheter, no leaking was observed.Based on the testing performed and the returned components, probable cause of the leaking cannot be determined as the catheter was not returned for the investigation.Teleflex will continue to monitor and trend for complaints of this nature.
