The reported event was inconclusive.No sample was returned for evaluation.According to the instructions for use (ifu), this device should be inflated with an eagle inflation device.However, the event appears to lean toward the use of syringe to inflate the balloon.However, without knowing in the event if the syringe was directly attached to the dilation catheter this could not be confirmed.A potential root cause could be due to "inadequate material selection" or "occlusion of fluid path".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: "inflating the balloon catheter 1.Fill the inflation device (eagle¿ inflation device) with sterile, liquid media.2.Attach the inflation device to the balloon lumen.3.Open the stopcock and inflate the balloon.4.Once dilation has been attained, advance the sheath over the balloon.Attaching the inflation device to the balloon dilation catheter: 1.Prepare and test the balloon dilation catheter according to the manufacturer¿s directions for use.2.If a separate syringe was used to prepare the balloon catheter, remove it.Create a fluid-fluid connection between the balloon and the connecting tube (male rotating adapter) of the inflation device by placing a drop of contrast solution from the syringe into each hub.3.Hand tighten the hubs securely.Balloon inflation and deflation: 1.Release the lock lever and allow the piston to move forward into neutral position (0 atm).2.To inflate the balloon, engage the lock lever, turn the palm grip on the piston clockwise slowly until the desired inflation pressure is reached.The lock lever maintains the increasing pressure.3.To deflate the balloon, push the lock lever left, releasing the piston, and pull back.Slide the lock lever back to lock, if desired.".
