The device was not returned for analysis.
The balloon rupture and separation were confirmed via photos provided by the account.
A review of the lot history record revealed no manufacturing nonconformities that would have contributed to this complaint.
Additionally, a review of the complaint history of the reported lot revealed no other complaints.
Based on the information provided, the balloon rupture, separation and difficult to remove appear to be due to case circumstances.
It is likely that the balloon rupture, difficult to remove, and subsequent separation occurred due to interaction with anatomical structures or other devices within the anatomy or as a result of the use of a non pressure monitored inflation device.
The additional therapy to remove the separated portion was due to the case circumstances.
There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.

It was reported that the procedure was performed to treat an atrioventricular fistula with mild tortuosity and 80% stenosis.
An 8 x 40mm armada 35 balloon dilation catheter (bdc) was prepped without any issues and advanced to the target lesion without any resistance; however, while attempting to inflate the balloon of the bdc, the balloon ruptured after two inflations at an unknown pressure.
It was noted that the physician inflated the balloon by hand; therefore, it is unknown if the balloon was inflated beyond nominal pressure.
While attempting to remove the balloon, resistance was noted with the anatomy and a portion of the balloon detached and remained in the anatomy.
A snare device was then inserted, and the detached pieces were successfully retrieved from the anatomy.
There was no reported clinically significant delay in the procedure.
No additional information was provided.
