(b)(4).The customer returned one three lumen cvc and a 10 ml syringe for evaluation.Visual examination of the sample revealed a hole on the left side of the juncture hub.The hole was flared out, indicating that excessive pressure caused the hub to burst.Signs-of-use in the form of adhesive residue was also observed on the extension lines.No other defects or anomalies were observed.The catheter was functionally tested by injecting water into all three extension lines using a lab inventory syringe.When injecting the proximal lumen, water leaked from the hole in the juncture hub.No leaks were observed when injecting through the other two lumens.A device history record review was performed with no relevant findings to suggest a manufacturing issue.The ifu provided with the kit cautions the user, "use of a syringe smaller than 10 ml to irrigate or declot an occluded catheter may cause intraluminal leakage or catheter rupture." the reported complaint of a "juncture hub leak in use" was confirmed by complaint investigation of the returned sample.The catheter contained a small hole in the back of the juncture hub.The hole was flared out , indicating excessive force caused the hub to burst.Functional inspection revealed that the water leaked form the juncture hub when injecting water through the proximal lumen.A device history record review was performed with no relevant findings to suggest a manufacturing issue.Based on the sample received and the customer description, unintentional user error likely caused or contributed to this event.Teleflex will continue to monitor and trend for reports of this nature.
