(b)(4).Additional information received from the customer indicates "there were no kinks, bends or deformities with cvc catheter".It was also reported that "no patient harm, injury, or health consequences occurred from this event".The customer provided four photos for analysis.The images showed the product lidstocks and components included within each kit.The customer also returned one opened 2-l cvc kit, including one 2-l catheter and guide wire assembly for analysis.Definite signs of use were observed within the extension lines and on the catheter body.Visual analysis of the catheter revealed no obvious defects or anomalies.The overall length of the catheter measured 5 1/8" which is within the specification limits of 4 13/16" - 5 3/16" per the catheter product drawing.The catheter outer diameter measured 0.0545".Which is within the specification limits of 0.054" - 0.058" per the catheter extrusion graphic.The catheter was functionally tested per the instructions per use provided with this kit, which instructs the user, "flush each lumen with sterile normal saline for injection to establish patency and prime lumen(s)." both extension lines were flushed using a lab inventory syringe, and both flushed as intended.No blockages were identified.A manual tug test confirmed that both extension lines were secure within their respective luer hubs.A device history record review was performed and no relevant findings were identified.The ifu informs the user, "do not apply excessive force in placing or removing catheter or guidewire.Excessive force can cause component damage or breakage.Ensure catheter patency prior to use.Do not use syringes smaller than 10 ml (a fluid filled 1 ml syringe can exceed 300 psi) to reduce risk of intraluminal leakage or catheter rupture.".The customer report of a blocked catheter was not confirmed through investigation of the returned sample.The catheter passed all relevant dimensional and functional requirements, and a device history record review revealed no relevant findings.Based on the customer report and the sample received, no problem was found.Teleflex will continue to monitor and trend on reports of this nature.Corrected data: section a.2.-age corrected to 2 months section a.3.-sex corrected to 'unknown'.Section a.4.-weight corrected to 4 kilograms.Section b.3.-date of event corrected to 09-may-2023.Section b.4.-date of this report corrected to 30-may-2023.
