Claim Text:
1. A method for supporting a wall in a junction of a blood vessel, the junction comprising a main branch, a first branch and a second branch, the method comprising: positioning a stent having a cylindrical wall comprising a first circumference along a length extending from a first end to a second end along a first axis, the cylinder wall further comprises a side aperture located at a fixed position with respect to the first and the second ends wherein the side aperture extends along a longitudinal direction and along a latitudinal direction to form a perimeter and the cylinder wall including a first marker in-line with and directly extends from the location where the distance of the aperture along the latitudinal direction is the greatest, the first marker extending along a circumference of the cylinder wall a distance substantially perpendicular to a longitudinal axis of the cylinder wall so as to provide a rotational orientation of the cylinder wall in a two dimensional image, wherein positioning the stent places the side aperture in the junction; expanding the cylinder wall so as to support the wall of the main branch and the first branch, whereby the side aperture allows the main branch to continue to feed both the first and the second branch; and expanding a flexible extension extending in a substantially continuous form from a portion of the side aperture's perimeter that flexes outward from the cylinder wall to form a protrusion that arches in a direction over the perimeter and extends into the second branch.
