During preparation for a micro neurosurgery, the hospital staff noticed that the apollo wand (wand) was not working properly upon attaching it to the apollo generator and testing the apollo system.It was reported that the wire within the wand was not activated when depressing the apollo generator foot pedal (foot pedal) on the apollo system.Therefore, the physician opened a new wand, tested it and used it to complete the procedure.

Results: the apollo wand (wand) was leaking where the tubing connects to the rotating hemostasis valve (rhv).Conclusions: evaluation of the returned device revealed that the wire inside the wand was activated when depressing the foot pedal on the apollo system.The wand was connected to an apollo system and powered on.The foot pedal to the apollo generator was depressed and vibration was observed.Therefore, the reported lack of vibration could not be confirmed.Further evaluation of the wand revealed a leak.During functional analysis, while attempting to aspirate and irrigate the wand, two leaks were observed where the tubings are connected to the rotating hemostasis valve (rhv).The root cause of these leaks could not be determined.Penumbra wands are visually inspected during in-process inspection and during quality inspection after manufacturing.The manufacturing records for this lot were reviewed and did not reveal any outstanding discrepancies, design, or quality concerns.
