It was reported that the urinary catheter was difficult to remove and that when it was removed, the device was noted to have a "ring" in the area of the retention balloon.According to the reporting facility, the patient experienced "urethral trauma and bleeding." despite multiple good faith attempts the reporting facility was unable or unwilling to provide additional information to the manufacturer.A sample of only the tip of the urinary catheter was returned to the manufacturer for evaluation.Inspection of the urinary catheter tip identified that it was cut just below the length of the retention balloon.The retention balloon was noted to have not returned to its original shape and the lumen of the retention balloon was found to be cuffed.If the retention balloon is not passively deflated, the introduction of negative pressure may lead to lumen cuffing and difficult removal of the urinary catheter.Based on the condition of the returned sample, the suspected root cause is improper deflation of the retention balloon.Due to the reported incident, and in an abundance of caution, this medwatch is being filed.If additional information becomes available a supplemental medwatch will be filed.
