The patient was undergoing a thrombectomy procedure in the vertebral artery using a penumbra system red72 reperfusion catheter (red72) and a non-penumbra sheath.During the procedure, the physician broke the red72 and it began to unravel.Therefore, the red72 was removed.The procedure was completed using a new red72.There was no report of an adverse effect to the patient.

Evaluation of the red72 confirmed that the catheter was fractured.This damage typically occurs if the catheter is forcefully retracted against resistance.If the catheter is retracted against resistance, the catheter may begin to stretch.Subsequent retraction against resistance may cause the catheter to eventually fracture.Further evaluation revealed ovalization on the proximal end of the catheter shaft.This damage was incidental to the reported complaint.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.
