The patient was undergoing a thrombectomy procedure for an acute-stage cerebral infarction using a penumbra system 3max reperfusion catheter (3max) and a penumbra system 5max ace reperfusion catheter (5max ace).During preparation for the procedure, the physician noticed that the 3max was already damaged and its blade was completely exposed upon removal from the packaging hoop.The damaged 3max was found prior to use and therefore, was not used for the procedure.The physician then opened a new 3max for the procedure and advanced it to the target vessel while inserting another manufacturer's guiding balloon catheter into the internal carotid artery (ica).Next, the physician started to aspirate the thrombus using the 3max and 5max ace; however, aspiration was not sufficient enough to completely remove the thrombus.Therefore, a stent retriever was advanced through the 5max ace in order to completely remove the thrombus.There was no report of an adverse effect to the patient.

Result: the penumbra system 3max reperfusion catheter (3max) was fractured approximately 9.0 cm from the hub.Conclusion: evaluation of the returned device revealed that the 3max was fractured.This type of damage typically occurs due to improper handling during preparation for use.If the 3max is forcefully manipulated or handled at extreme angles, damage such as this may occur.Penumbra catheters are 100% visually evaluated during in-process inspection.The manufacturing records for this lot were reviewed and did not reveal any outstanding discrepancies, design, or quality concerns.
