The patient was undergoing a thrombectomy procedure in the basilar artery for acute cerebral infarction using penumbra system max 3 reperfusion catheter (3 maxc).During the procedure, the physician encountered resistance while inserting the guide wire into the 3 maxc and the 3 maxc was not used.It was reported that the 3 maxc could have been ovalized.The physician then inserted the guidewire into another 3 max; however, he could not catch the clot with it.The physician successfully completed the procedure by using the same 3 maxc and a penumbra system ace 68 reperfusion catheter (ace68).There was no report of an adverse effect to the patient.

Results: the 3maxc was kinked approximately 85.5 cm from the hub.The device was ovalized approximately 112.0 cm from the hub.Conclusions: evaluation of the returned 3maxc revealed a kink.If the device is forcefully advanced against resistance, damage such as a kink may occur.During functional testing, a demonstration guidewire was advanced through the 3maxc without an issue.The non-penumbra guidewire identified in the complaint was not returned for evaluation; therefore, the root cause of the resistance experienced during the procedure could not be determined.Further evaluation revealed an ovalization.This damage was likely incidental to the reported complaint.Penumbra catheters are 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.H3 other text : placeholder.
