Abstract: In a method of the present invention, a wire stent, having a cylindrical shape defined by a series of alternating longitudinally overlapping opposing loops, is fabricated from a wire formed into a planar serpentine configuration. The wire is centered over a semi-cylindrical trough in a flat plate and then pressed into the trough by a forming bar so that a portion of the wire assumes the semi-cylindrical shape. A pulling tool, having a hook at one end, is engaged at the hook with the exposed loops of the serpentine configuration for pulling the exposed loops over the exposed portion of the forming bar to form a generally cylindrical shape from the wire. Once the wire is extracted from the trough and the forming bar is removed, a folded balloon catheter is inserted through the cylindrical shape and the wire is tightly pressed about the catheter.
