The reported event was confirmed.Seven unopened silastic catheters were returned.A third catheter was opened and it was found that the catheter's drainage funnel appeared to be poorly trimmed.The catheter was inflated with air and passively deflated with no issues.The same process was repeated with 10ccs of water and initially no water returned.The syringe was screwed further and the balloon passively deflated with no issues.Upon closer examination it was found that the catheter cap was misaligned.A potential root cause for this failure could be "dipping too shallow - incorrect fluid level in the slurry tank".The device history record was reviewed and found nothing that could have caused or contributed to the reported event.The instructions for use were found adequate and state the following: ¿to deflate catheter balloon: gently insert a luer slip tip syringe in the catheter valve.Never use more force than is required to make the syringe ¿stick¿ in the valve.Allow the pressure within the balloon to force the plunger back and fill the syringe with water.If you notice slow or no deflation, re-seat the syringe gently.Use only gentle aspiration to encourage deflation if needed.Vigorous aspiration may collapse the inflation lumen, preventing balloon deflation.If necessary, contact adequately trained professional for assistance, as directed by hospital protocol.Should balloon rupture occur, care should be taken to assure that all balloon fragments have been removed from the patient." h11:section a through f - the information provided by bd represents all of the known information at this time.Despite good faith efforts to obtain additional information, the complainant / reporter was unable or unwilling to provide any further patient, product, or procedural details to bd.
