Qn#(b)(4).The customer returned one, single-lumen midline catheter for analysis.Signs-of-use in the form of biological material was observed on the luer hub.Visual analysis of the sample revealed that the catheter body was severed just below the 12cm mark.The edges of the point of separation appears smooth indicating that the customer intentionally cut the catheter body.The separated portion was not returned for analysis.No other defects or anomalies were observed.The extension line length from the luer hub to the juncture hub measured 1.64", which is consistent with the nominal value of 1.63" per the midline catheter product drawing.The extension line outer diameter measured.093", which is within the specification limits of.093"-.097" per the extension line extrusion product drawing.The extension line inner diameter measured.057", which is within the specification limits of.055"-.059" per the extension line extrusion product drawing.A leak test was performed on the catheter.With the distal end of the catheter body occluded, water was injected through the catheter at 45psi for 30 seconds.No leaks were observed on the extension line or the catheter body.A manual tug test confirmed that the extension line was secure to the luer hub and the juncture hub.A device history record review was performed with no relevant findings to suggest a manufacturing related cause.The ifu provided with the kit warns the user, "use only lumen(s) labeled 'pressure injectable' for pressure injection to reduce risk of catheter failure and/or patient complications." the ifu also warns, "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 an extension line leak could not be confirmed through complaint investigation.Visual analysis did not reveal any holes on the extension line.Additionally, the catheter met all relevant dimensional and functional requirements.A leak test was performed and no leaks were observed.A device history record review did not reveal any reliant findings to suggest a manufacturing related cause.Based on the sample received and the report from the customer, no problem could be found with the returned sample.Teleflex will continue to monitor and trend for reports of this nature.
