Block h6: problem code 1149 captures the reportable event of balloon failed to deflate.Visual examination of the returned complaint device found that only the distal part of the device was received, and the balloon was found to be twisted.A microscopic examination of the device found that the catheter had been cut, which is consistent with what the customer reported.Functional evaluation could not be performed due to the condition of the device, and therefore the reported problem of deflation failure cannot be confirmed.It is possible that factors encountered during the procedure, the interaction with the scope, prolonged procedure, and/or the technique used by the physician during the insertion could have caused the twist in the balloon and, for this reason, was difficult to inflate and deflate.Also, this twist in the balloon could have caused the physician to feel some resistance when being pulled out from the patient, resulting in the physician needing to cut the catheter for removal.Therefore, the most probable root cause is adverse event related to procedure.A review of the device history record (dhr) was performed and confirmed that this device met all material, assembly and performance specifications.A labeling review was performed and from the information available, this device was used per the instructions for use (ifu)/product label.
