Methods and systems for bypassing occlusions in a femoral artery

摘要

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.

主权项

1. A method for bypassing an occlusion in a peripheral artery, said method comprising:
forming a proximal penetration from the peripheral artery to an adjacent peripheral vein at a location above the occlusion; advancing a penetration guidewire down the peripheral artery, through the proximal penetration, and into the peripheral vein; pulling the penetration guidewire through an external penetration below the occlusion; advancing a penetration catheter downward over the penetration guidewire from the peripheral artery into the peripheral vein; penetrating a penetration tool carried by the penetration catheter from the peripheral vein into the peripheral artery at a location below the occlusion to form a distal penetration; and placing a stent graft placement guidewire from the peripheral artery, through the proximal penetration, down the peripheral vein, and through the distal penetration back into the peripheral artery; deploying a stent graft from a catheter disposed over the stent graft placement guidewire.
