Customer reported some lumens of the cvc were obstructed and couldn't be used.It first occurred with the blue lumen, where sedation with dormicum and sufenta and ringer's was administered at a flow of at least 10 ml/hr up to 42 ml/hr.The grey medial lumen was also occluded.The occlusion alarm sounded several times and it was possible to irrigate against resistance, but suddenly this was no longer possible.There was no patient injury.Another lumen was used.It was reported the cvc was cut open and there was a large blood clot in the system.It was reported the patient was on ventilation with covid at the time of this report.

(b)(4).The customer returned one, unopened cvc kit for analysis.It is being assumed that this is a representative sample.The seal was completely intact around the entire kit.The kit was opened to analyze the kit contents.Visual analysis of the catheter did not reveal any defects or anomalies.Visual analysis could not be performed on the actual catheter involved with this complaint as it was not returned.The length of the returned catheter measured 170mm which is within the specification limits of 157mm-177mm per the catheter graphic.The catheter body outer diameter measured 2.87mm which is within the specification limits of 2.87mm-2.97mm per the catheter extrusion graphic.The ifu provided with the kit informs the user, "ensure catheter patency prior to use".All four of the catheter lumens were flushed with a lab inventory syringe.No defects or anomalies were observed.A device history record review was performed, and no relevant findings were identified.The ifu provided with this kit informs the user, "do not secure, staple and/or suture directly to outside diameter of catheter body or extension lines to reduce risk of cutting or damaging the catheter or impeding catheter flow.Secure only at indicated stabilization locations".The report of a blocked catheter was not able to be confirmed through complaint investigation.Visual analysis revealed that the customer returned one representative sample for analysis.All relevant dimensional and functional requirements were met, and a device history record review was performed with no relevant findings.Based on the customer report and the sample received, the root cause cannot be determined at this time without the actual complaint sample returned for analysis.Teleflex will continue to monitor and trend for reports of this nature.
