Event Description
|
Medtronic received information that an axium coil could not be detached.When the hypotube was broken as the healthcare provider (hcp) always does, there was no inner wire to pull and detach the coil.So the coil can not be detached and was able to be pulled out of the aneurysm.The devices were prepared according to the instructions for use (ifu).The patient's blood flow and vessel tortuosity were normal.No patient symptoms or complications were reported.
