  • Patent number: 12263105
    Abstract: A system for deploying a stent-graft from the femoral artery into the femoral vein and back into the femoral artery in order to bypass a femoral occlusion comprises a penetration catheter and a guidewire capture and stabilization catheter. The penetration catheter may be advanced contralaterally to a location above the occlusion and the capture and stabilization catheter may be introduced upwardly through the femoral vein. The penetration tool on the penetration catheter is used in multiple steps to deploy guidewires which are then used to deploy the stent-graft in the desired location.
