The device was returned for analysis.
The reported inflation problem was able to be confirmed.
Additionally returned goods analysis identified there was fluid was leaking from the tip at 16 atmospheres.
There was a pinhole in the proximal taper of the balloon and a tear noted in the inner member.
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.
As there was no report of a leak during preparation for use, the investigation determined the reported difficulties appear to be related to circumstances of the procedure as it is likely that interaction with the guide wire and/or other devices resulted in the noted inner member tear, the noted scratched proximal balloon marker and the noted balloon material pinhole; thus resulting in the reported inflation problem/noted leaks (pinhole, tip).
The noted multiple bends on the hypotube likely occurred due to handling or during packing for return analysis.
There is no indication of a product quality issue with respect to manufacture, design or labeling.
