1. A stent system configured to support a wall of at least one junction of a bodily vessel, the junction comprising a main branch, a first branch and a second branch, comprising:
a stent having a cylinder wall configured to be expanded from a first state to a second state, wherein at the first state, the cylinder wall comprises a first circumference along a length extending from a first end to a second end along a first axis, a side aperture located at a fixed position with respect to the first and the second ends having a perimeter, and a flexible extension positioned substantially within the circumference; and wherein at the second state, the cylinder wall is configured to expand along its length configured to support the wall of the main branch and the first branch, to form a second circumference, wherein the second circumference is variable along the length of the cylinder and the flexible extension is configured to extend from a predefined portion of the side aperture's perimeter that, upon expansion of the stent, is configured to flex outward from the cylinder wall to form a hood-like protrusion that arches over the perimeter; and a first marker that upon expansion of the stent, is positioned in-line with and directly extending from a location where the distance of the aperture along the latitudinal direction is the greatest. |
