(b)(4) the customer returned one slic component for analysis.Signs of use were observed on the returned component.Visual analysis revealed that the luer hub was damaged and cracked.Microscopic examination confirmed that the luer hub had lateral cracks down the body.The appearance of the damage is consistent with overtightening of the luer hub.The overall length of the slic component is 6 1/8", which is within the specification limits of 5 7/8" - 6 1/8" per the slic product drawing.The catheter was functionally tested per the instructions for use (ifu) provided with this kit which states "ensure catheter patency prior to use.Do not use syringes smaller than 10 ml to reduce risk of intraluminal leakage or catheter rupture." the catheter was flushed with a lab inventory syringe, and a leak was observed at the level of the luer hub.The ifu provided with this kit informs the user, "hemostasis valve/side port assembly to slic connection and slic to obturator connection must be secured and routinely examined to minimize the risk of disconnection and possible air embolism, hemorrhage, or exsanguination".The customer report of a damaged luer hub was confirmed by complaint investigation of the returned sample.Visual and microscopic analysis revealed that the luer hub contained a crack.The appearance of the crack was consistent with over-tightening on the luer hub.Additionally, the component passed all relevant dimensional analysis.Based on the customer report and the sample received, unintentional use error caused or contributed to this event.Teleflex will continue to monitor and trend for complaints of this nature.
