Device evaluated by mfr.
: the device was returned for evaluation in two pieces.
There was blood and contrast inside ad outside of the device.
Microscopic and tactile inspection were done on the tip, distal shaft, collar and hypotube.
Inspection noted a kink in the distal outer located 8cm from the tip and a complete separation of the shaft (at the collar) with the polytetrafluoroethylene (ptfe) completely removed from the collar.
Functional testing could not be done, due to the damage on the device.
Inspection of the remainder of the device, apart from the observed damage, revealed no other damage or irregularities.
The investigation conclusion is operational context as the product meets the design & manufacture specification but due to anatomical/procedural factors encountered during the procedure, performance was limited.
