The patient was undergoing a thrombectomy procedure in the posterior tibial artery using an indigo system cat3 aspiration catheter (cat3) and a non-penumbra sheath.During the procedure, the physician advanced the cat3 through the sheath, then initiated the aspiration; however, no aspiration was observed and the cat3 was therefore removed.Upon removal, it was noticed that the cat3 was kinked at the midshaft.The physician then flushed the cat3 and it separated in two pieces exposing the inner coiling.The procedure was completed using a new cat3 and the same sheath.There was no report of an adverse effect to the patient.

Results: the cat3 was fractured approximately 57.0 cm from the hub and the support coil winds were exposed.The cat3 was ovalized approximately 131.0 cm from the hub.Conclusions: evaluation of the returned cat3 confirmed a fracture and the inner coil winds were exposed.Stress marks were observed near the fracture; this indicates that the device was likely kinked prior to fracturing.If cat3 is manipulated at an extreme angle during use, damage such as a kink and subsequent fracture may occur.Further evaluation of the returned cat3 revealed that the catheter was ovalized.This damage was likely incidental to the reported complaint.No other devices associated with the complaint were returned for evaluation.Penumbra catheters 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.H3 other text : placeholder.
