During preparation for a thrombectomy procedure, a penumbra system 3max reperfusion catheter (3maxc) broke in two parts near the hub upon removal from the packaging.The damage to the 3maxc occurred prior to use and, therefore, was not used in the procedure.The procedure was completed using another 3maxc.
|
Results: the 3maxc was fractured approximately 18.0 cm from the hub and yield marks were present on both sides of the fracture site.Conclusion: evaluation of the returned 3maxc revealed that the catheter was fractured.If the device is forcefully retracted out of its packaging hoop at extreme angles during removal from its packaging, damage such as a kink may occur.If a kinked device is further manipulated, the kink may worsen to a fracture.Further evaluation revealed yield marks were present on both sides of the fracture site, indicating that the catheter likely kinked prior to fracturing.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.
