Qn# (b)(4).The customer returned one cvc catheter for evaluation.Visual examination revealed obvious signs of use in the form of biological ma terial on the catheter body.Dimensional analysis of the returned catheter was performed based on the potential finished good and batch identified from the sales history of the customer.The total length of the catheter body measured to be 218 mm which is within s pecifications of 207mm - 227 mm per product drawing.The catheter body outer diameter measured 2.45 mm which is within the specification of 2.39 mm-2.49 mm per catheter body product drawing.The ifu provided with the potential finished good and batch identified from sales history states "flush each lumen of catheter with sterile saline solution, to establish patency and prime lumen(s)." the returned catheter was flushed using a water-filled lab inventory syringe.No blockages or leaks were detected in the white proximal lumen.When the distal and medial lumens were flushed, slight resistance was encountered as biological material exited the lumens.Once the lumens were cleared of biological material, the distal and medial lumens flushed as expected.The ifu provided with the potential finished good and batch provides the following warnings, cautions and instructions for the user: "practitioners must be aware of complications associated with central vein catheters including but not limited to: cardiac tamponade secondary to vessel wall, atrial or ventricular perforation, pleural(i.E., pneumothorax) and mediastinal injuries, air embolism, catheter embolism, catheter occlusion, thoracic duct laceration, bacteremia, septicemia, thrombosis, inadvertent arterial puncture, nerve damage, hematoma, hemorrhage, and dysrhythmias." "clinical assessment of patient must be completed to ensure no contraindications exist e.G.Allergies.This de vice is not recommended for use in the presence of device related infections or previous/current thrombosis" "flush each lumen of catheter with sterile saline solution, to establish patency and prime lumen(s)." the customer report of a catheter thrombosis could not be confirmed through complaint investigation.Dimensional and functional testing were performed based on the potential finished good and batch identified from sales history.The returned sample passed all relevant visual and functional testing.A device history record review was performed on a potential finished good and batch from sales history with no relevant findings.Additional information was received from the customer which identified that there were no alleged deficiencies or defects with the teleflex catheter.The customer reported the complaint solely due to the occurrence of a thrombosis.The complaint was reviewed by a member of the clinical and medical affairs team, which indicated that "thrombi have been found in cvcs of competitors after switching from arrow cvcs to competitor cvcs due to supply issues." based on the customer report and the sample returned, the patient condition likely caused or contributed to this event.Teleflex will continue to monitor and trend for complaints of this nature.
