Upon receipt, the catheter was immediately disinfected and photographed for investigation.The catheter was received as shown, with the tip cut off; the rest of the catheter was not returned.A small circuit was created by inserting the catheter tip into a container of water and connecting tubes to the barbs.A vacuum was pulled on the drainage line to pull the water through the venous lumen.The air leak could not be recreated with fluid in both lines of the circuit.It should be noted that the catheter was received and appeared to be smeared with an adhesive or sealant on the clear tubes.Since the lot number was not reported a specific batch record could not be investigated.Based on sales records, the last three lots of vv13f catheters shipped to nationwide (b)(6) hospital were all reviewed, no deviations were recorded on those lots.All catheters are inspected and undergo a pressure test prior to release, and all released catheters in these lots passed this pressure leak inspection.No similar complaints have been reported to origen on these lots or others.Based on this investigation, the cause for air in the circuit could not be determined.We will continue to pressure test all our catheters and monitor our complaints for any similar issues.

Air was noted to be in the ecmo circuit x2 during patient admit.It is unclear how the air was entering, there is concern that it is from the cannula even though there is no obvious defect.Device usage problem: device failed (e.G.Broke, couldn't get it to work or stopped working).
