Abstract:
1. A method for retrograde entry antegrade placement for femoral artery access, the method comprising: (a) advancing a curved needle through a skin of a patient at an entry point and into a lumen of a superficial femoral artery retrograde at a predetermined distance distal from an origin of a superficial femoral artery until a tip of the curved needle exits the common femoral artery and exits through the skin of the patient at an exit point proximal to the entry point; (b) advancing a first wire into and out of a lumen of the curved needle; (c) removing the curved needle completely from the first wire while leaving the first wire in place; (d) from the exit point, advancing over the first wire a dual-lumen access director into the common femoral artery antegrade and into the superficial femoral artery of the patient, wherein the dual-lumen access director receives the first wire in a first lumen that extends from the tip of the dual-lumen access director to the head of the dual-lumen access director; (e) advancing the dual-lumen access director until an oval orifice located proximal to the tip of the dual-lumen access director is just about to exit the superficial femoral artery, wherein a second lumen extends from the head of the dual-lumen access director to the oval orifice of the dual-lumen access director; (f) advancing a second wire down the second lumen of the dual-lumen access director until the tip of the second wire exits through the oval orifice and into the superficial femoral artery; (g) removing the dual-lumen access director completely from the first and second wires while leaving the first and second wires in place; (h) removing the first wire completely from the superficial femoral artery and the common femoral artery and out of the skin of the patient; and (i) advancing a sheath over the second wire, enabling further procedures within the superficial femoral artery antegrade.
