During processing of this complaint, attempts were made to obtain complete event, patient and device information.
Evaluation summary: visual and functional inspection was performed on the returned device.
The reported failure to flush was confirmed due to a pinhole in the balloon.
It is likely that the balloon rupture is the result of interaction with anatomy or associated devices causing damage to the outer surface of the balloon.
A review of the lot history record identified no manufacturing nonconformities issued to the reported lot that would have contributed to this event.
Additionally, a review of the complaint history revealed no other incidents.
The investigation determined the reported difficulties appear to be related to circumstances of the procedure.
There is no indication of a product quality issue with respect to the design, manufacture, or labeling of the device.

Another bdc was used to complete the procedure.
There were no adverse patient effects and no reported clinically significant delay in the procedure.
Returned device analysis identified fluid was observed coming out from a pinhole in the balloon.
