The patient was undergoing a thrombectomy procedure using an indigo system aspiration catheter 6 (cat6).During the procedure, while inserting the cat6 into another manufacturer's sheath, the physician inadvertently crushed the distal end of the cat6.Therefore, the cat6 was removed.After removal of the cat6 from the sheath, the physician noticed that the distal end was separated from the rest of the cat6.The procedure was then completed using a new cat6 and the same sheath.There was no report of adverse effect to the patient.
