It was reported after insertion, while the lines were checked, the physician observed there was no backflow on the distal line.A new catheter was inserted and the same issue occurred with the second catheter.It was decided to leave the second catheter inserted in the patient.No patient harm or consequence reported.

(b)(4).Associated mdr#s: 3006425876-2023-00362.The customer returned one 3-l cvc for analysis.Significant signs of use in the form of biomaterial were observed on the catheter body and inside the extension lines.Initial visual inspection of the catheter revealed no obvious defects or anomalies.The catheter body length from the juncture hub to the distal end measured 214mm , which is within the specifications of 208.5-225mm per product drawing.Functional inspection of the catheter was performed per the instructions for use (ifu) provided with the kit which states, "flush each lumen with sterile normal saline for injection to establish patency and prime lumen(s)." the medial and proximal extension lines flushed as expected, with no leaks or blockages observed.While flushing the distal lumen, it was noted that water would not exit the distal end of the catheter despite significant pressure being applied, indicating a blockage.A long pin gauge was inserted through the catheter to determine the location and source of the blockage.Significant amounts of biomaterial were removed from the distal lumen of the catheter.Once the biomaterial was removed, the functional test was repeated, and water was observed exiting the distal end as intended.A device history record review was performed, and no relevant findings were identified.The instructions for use (ifu) provided with the kit warns the user , "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 extension line was confirmed through complaint investigation of the returned sample.Functional inspection revealed the distal lumen was blocked due to an excess of biomaterial within the lumen.The returned catheter met all relevant dimensional requirements, and a device history record review was performed with no relevant findings.Based on these circumstances, unintentional use error likely caused or contributed to this event.Teleflex will continue to monitor and trend for complaints of this nature.
