Device evaluated by mfr: returned product consisted of an nc emerge balloon catheter.
The balloon was loosely folded.
There was contrast in the inflation lumen.
The outer shaft, inner shaft, balloon and tip were microscopically examined.
The hypotube shaft was completely separated 30 cm from the hub and 65 cm from the tip.
The fracture faces were oval as if kinked prior to separation.
There were numerous hypotube kinks.
There was tip damage.
There was no evidence of any material or manufacturing deficiencies contributing to the damage.
The manufacturing batch record review confirmed that the device met all material, assembly and performance specifications.
The most probable root cause is considered handling damage as the event occurred without direct patient contact.
