It was reported that during a fistulaplasty for the patient's arm, the advance 35 lp low profile balloon catheter ruptured after being inflated to pressure less than the rated burst pressure (rbp) of 10 atmosphere (atm) in a very tight stricture.A mixture of contrast solution and saline using an inflation device was used to inflate the balloon.Upon removal of the balloon catheter, it was noted that the balloon ruptured in a circumferential manner as opposed to a longitudinal fracture.The surgeon encountered difficulty in removing the balloon catheter through the seven (7) fr sheath being utilized, and felt as though it might snap.The surgeon proceeded to remove the balloon catheter, sheath and wire guide together as the ruptured balloon was unable to be removed through the sheath.The patient did not require any additional procedures due to this occurrence.According to the initial reporter, the patient did not experience any adverse effects due to this occurrence.

Investigation evaluation: a review of the dimensional verification, complaint history, device history record, documentation, drawing, instructions for use (ifu), manufacturing instructions, quality control, specifications, and a visual inspection of the returned device were conducted during the investigation.The visual inspection of the returned device noted that the low profile balloon catheter was returned inserted through a 7 french catheter from an unknown manufacturer.The balloon catheter moved freely over the catheter.A wire guide with a diameter of 0.03485 inches was exiting the proximal end of the balloon catheter.The length of wire guide exiting the proximal end was 55.8 cm.When attempting to remove the wire, it was noted that the wire guide was elongated.The wire guide could not be removed from the balloon catheter.Both marker bands were present on the balloon catheter.The balloon tubing was measured to be 14.4 cm in length.Additionally, a document based investigation evaluation was performed.There is no evidence to suggest the product was not made to specifications.A review of the device history record showed no nonconforming events which could contribute to this failure mode.It should be noted there were no other reported complaints for this lot number.Based on the information provided, the examination of the returned product, and the results of our investigation, the root cause was determined to be related to the usage or handling of the product.We will continue to monitor for similar complaints.Per the quality engineering risk assessment, no further action is required.This report is required by the fda under 21 cfr part 803.This report is based on unconfirmed information submitted by others.Neither the submission of this report nor any statement made in it is intended to be an admission that any cook device is defective or malfunctioned; that a death or serious injury occurred; or that any cook device caused or contributed to; or is likely to cause or contribute to a death or serious injury if a malfunction occurred.
