1. An assembly for opening a vessel lumen comprising:
- a radially expandable stent configured to open the vessel lumen, said radially expandable stent comprising a curved wall having a proximal portion, a distal portion, and a lumen connecting said proximal portion and said distal portion;
a knitted stent jacket comprising a tubular wall that substantially surrounds an exterior surface of said radially expandable stent; and
a plurality of buffering element cords having an external surface placed against an external surface of said knitted stent jacket, covering only a minor portion of a surface of the knitted stent jacket, in a manner which spaces the knitted stent jacket from an adjacent element of the assembly to buffer the knitted stent jacket from movement of the adjacent element, wherein each of the plurality of buffering element cords has a thickness greater than the knitted stent jacket and an entire length of each of the plurality of buffering element cords overlays the knitted stent jacket,wherein said knitted stent jacket comprises at least three interconnected loops at its distal end, at least one first loop, at least one second loop and at least one third loop; and
wherein the assembly comprises at least one separate retainer belt having at least one portion woven through said at least one first loop, past said at least one second loop and through said at least one third loop;
said at least one second loop configured to create a run in said knitted stent jacket upon expansion of said radially expandable stent, wherein the distal end forms a terminal end of the knitted stent jacket and the at least three interconnected loops are arranged circumferentially at the terminal end.
