The patient was undergoing a thrombectomy procedure in the right internal carotid artery (ica) using a penumbra system red 72 reperfusion catheter (red72), a benchmark bmx96 access system (bmx96), a non-penumbra microcatheter, a non-penumbra stent retriever and a guidewire.It was noted that the patient¿s anatomy was tortuous.During the procedure, the physician used radial approach and completed the first pass with aspiration using the red72 and stent retriever.While removing the red72 after the first pass aspiration, the physician noticed unwinding of the red72 at the distal end.The physician removed all the catheters and switched to femoral access.The procedure was completed with two more passes using a non-penumbra sheath, a non-penumbra catheter, the same microcatheter and the same stent retriever.Thrombolysis in cerebral infarction (tici) grade 2b was achieved.There was no report of an adverse effect to the patient.

Evaluation of the returned red72 confirmed a fracture and revealed that the catheter was ovalized near the fractured location.If the parent device becomes kinked while the red72 is inserted, damage such as a kink/ovalization may occur.This damage may contribute to resistance during retraction.Forceful retraction against this resistance likely contributed to the fracture.Further evaluation revealed kinks and ovalization along the proximal shaft, and consecutive kinks along the distal fractured segment.The distal kinks were likely due to manipulation against resistance during the procedure.The proximal damage was likely incidental to the complaint and may have occurred during packaging for return to penumbra.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.
