The patient was undergoing a thrombectomy procedure using a penumbra system aspiration pump max 110v (pump max).During the procedure, the physician successfully used a pump max with an indigo system aspiration catheter 8 (cat8) for about 10 to 15 minutes.After removing the cat8 for flush, the pump max powered off by itself.All the electrical cords were checked and the pump max was turned on again; however, the pump max powered off again after working for about 10 seconds.Therefore the procedure was successfully completed using another pump max and the same cat8.There was no report of an adverse effect to the patient.
