As reported by a healthcare professional, during coil embolization to treat anterior communicating artery subarachnoid hemorrhage, when the physician attempted to detach the orbit galaxy (640cf0515/17298690) with the dcs syringe ii (635002/96331262), the embolic coil unexpectedly moved and the gauge of the syringe did not move from the detach zone.The galaxy and the syringe were both replaced with new devices because, even though the physician would have preferred to re-loop the coil inside the aneurysm again, he was apprehensive of premature detachment of the coil.There was no difficulty in removing the coil, and no damage was noted on the coil after removal.This was the first use of the syringe, and it had not previously exceeded the green zone/position 3.Prior to attempting to detach the coil, it was verified under fluoro that there was no stress against the microcatheter or delivery tube.The dcs syringe pressurized as intended.Another galaxy of the same size was then successfully detached in the aneurysm using a new dcs syringe.The procedure was completed without further issues or delay.There were no patient injuries or complications.The complaint products were new and stored per labeling instructions.The procedure was conducted in accordance with the ifu, and the constant flush had been maintained at all times.No visible damages were noted on the products prior to the event.Due to the infection, the complaint products were not returned for analysis.No further information was available.
