(b)(4), the customer returned one, 2-lumen hemodialysis catheter.Signs of use in the form of biological material were observed.Visual analysis did not reveal any defects or anomalies.The catheter length from the juncture hub to the distal tip measured 217mm, which is within the specification limits of 207mm-227mm per the catheter product drawing.The catheter body outer diameter measured 4.69mm, which is within the specification limits of 4.62mm-4.72mm per the catheter extrusion product drawing.The catheter was assembled and functionally tested per the instructions for use (ifu).The ifu provided with this kit states , "prepare catheter for insertion by flushing each lumen and clamping or attaching injection caps to appropriate extension lines".The catheter was flushed with a lab inventory syringe filled with water; no leaks or blockages were detected.Amrq-000162 states, "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-10555-1 annex c".Both luer hubs of the catheter were connected to the leak tester.With the distal end occluded, the catheter was pressurized to 300kpa for 30 seconds.No leaks detected.A manual tug test confirmed both the arterial and venous luer hubs were securely attached to their extension lines.The customer did not provide a lot number; therefore, a device history record review was performed based upon a lot number from the sales history data of the customer.No relevant findings were identified.The ifu provided with the kit informs the user, "practitioners must be aware of complications associated with central vein catheters including cardiac tamponade secondary to vessel wall, atrial or ventricular perforation, pleural and mediastinal injuries, air embolism, catheter embolism, thoracic duct laceration, bacteremia, septicemia , thrombosis, inadvertent arterial puncture, nerve damage, hematoma, hemorrhage, dysrhythmias, brachial plexus injury, cardiac arrhythmia, exsanguination, hemothorax, luminal thrombosis, pneumothorax , subcutaneous hematoma, and retroperitoneal bleed".The report of an air embolism could not be confirmed as part of this complaint investigation.The returned catheter met all relevant visual, dimensional, and functional requirements including leak testing performed per bs en iso-10555-1.A device history record review was performed based on a potential lot identified from a sales history review.No relevant findings were identified to suggest a manufacturing related issue.Based on the customer report and the sample received, no problem was found with the returned device.Teleflex will continue to monitor and trend for reports of this nature.
