A vascular method is disclosed comprising introducing a first flexible wire into a blood vessel, wherein the blood vessel has a first vessel end and a second vessel end and wherein the first flexible wire has a first end and a second end, sliding an angiotip along the first flexible wire in a direction away from the first end of the wire and toward the second end of the wire, frictionally engaging the first flexible wire with the angiotip, and pulling the first flexible wire through the blood vessel in the direction of the second vessel end, wherein the pulling of the first flexible wire pulls the angiotip through the blood vessel in the direction of the second vessel end.
