The device was not returned for analysis.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 identified no other incidents from this lot.It is possible that interaction with the guide liner and/or other devices resulted in compromising the inflation/deflation lumen thus resulting in the reported deflation problem and difficult to remove; however this cannot be confirmed.Manipulation of the device in attempts to remove resulted in the reported material separation.As reported, all parts of the separated device were removed, except for the balloon portion with the markers.The separated inflated balloon with markers was left in the aneurysm that was going to be occluded.There is no indication of a product quality issue with respect to manufacture, design or labeling.

It was reported that during an aneurysm repair procedure, the trek rx was advanced and inflated.A guide liner was advanced over the balloon.Attempts were made to deflate the balloon, but it failed to deflate.Some trouble shooting was performed, but the balloon still could not be deflated.During removal of the inflated balloon, it was pulled into the guide catheter, but broke mid-shaft.The separated portion was snared and pulled into the guide catheter, but the shaft broke again.All parts of the separated device were removed, except for the balloon portion with the markers.After a surgical consult the separated inflated balloon with markers was left in the aneurysm that was going to be occluded.The patient remained stable and remained hospitalized for another day for monitoring.No additional information was provided.
