(b)(4) the customer report of an extension line leak was confirmed through investigation of the returned sample.The customer returned one s-l picc catheter for analysis.Definite signs of use in the form of biomaterial were found on the catheter body.Initial visual analysis of the catheter revealed no obvious defects or anomalies.After failing functional testing, a hole was observed on the extension line adjacent to the juncture hub.The edges of the hole were smooth and uniform.The appearance of the hole is consistent with damage resulting from contact with a sharp instrument (i.E., scissors, scalpel, etc.).No other defects or anomalies were observed on the catheter.The overall length of the catheter measured 20" via calibrated ruler which was within the specification limits of 19.812" - 20" per the catheter product drawing.The outer diameter (od) of the catheter measured 0.0545" which was within the specification limits of 0.0540" - 0.0570" per the catheter extrusion graphic.The outer diameter of the distal extension line measured 0.0945" which was within the specification limits of 0.0930" - 0.0970" per the distal extension line graphic.Both these measurements were done via calibrated caliper.The inner diameter (id) of the distal extension line measured 0.059" via calibrated pin gauge which was within the specification limits of 0.055" - 0.059" per the distal extension line graphic.The catheter was functionally tested per the instructions for use (ifu) provided with this kit which instructs the user, "flush each lumen with sterile normal saline for injection to establish patency and prime lumen(s)." the catheter was connected to a lab inventory ars and flushed, and the catheter flushed as intended.The returned catheter was then tested per bs en iso which states that there shall be no liquid leakage in the form of a falling drop of water at 300-320 kpa (43.5-46.4 psi) for 30 sec when tested per bs en iso.The catheter was connected to lab leak tester and pressurized to 300 kpa for 30 seconds.A leak was observed on the extension line towards the juncture hub, confirming the customer report.A manual tug test confirmed that the extension line was secure within its luer hub.The ifu provided with this 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." a device history record review was performed, and no relevant findings were identified.Based on the customer report and the sample received, unintentional user error likely caused or contributed to this event.Teleflex will continue to monitor and trend on reports of this nature.
