Qn# (b)(4).The customer returned one catheter and guide wire assembly for analysis.No definite signs of use were observed on the returned components.Visual analysis of the luer hubs revealed no cracks or scratches.No obvious defects or anomalies were noted to the other components.The outer diameter of the distal extension line measured 4.741mm which is within the specification limits of 4.70mm - 4.80mm per the extension line graphic.The inner diameter of the distal extension line measured 2.921mm , which is within the specification limits of 2.90mm - 3.00mm per the extension line graphic.The outer diameter of the proximal extension line measured 4.72mm which is within the specification limits of 4.70mm - 4.80mm per the extension line graphic.The inner diameter of the proximal extension line measured 2.921mm, which is within the specification limits of 2.90mm - 3.00mm per the extension line graphic.The catheter was functionally tested per the instructions for use (ifu) provided with this kit which instructs the user, "check lumen patency by attaching a syringe to each extension line and aspirate until free flow of venous blood is observed." the catheter was flushed using a lab inventory syringe , and the catheter flushed as intended.A device history record review was performed and no relevant findings were identified.The ifu as part of this kit informs the user, "do not apply excessive force in placing or removing catheter or guidewire.Excessive force can cause component damage or breakage." the customer report of a cracked luer hub could not be confirmed through investigation of the returned sample.The catheter passed all relevant dimensional and functional requirements, and a device history record review revealed no obvious defects or anomalies.Based on the customer report and the sample received, no problem was found on the returned device.Teleflex will continue to monitor and trend on reports of this nature.
