A stent for providing support to a body lumen comprises a wire wound in a continuous winding into a generally cylindrical shape with the cylindrical shape terminating at one end in a closed loop of the wire and a line of elongated flexible material extending through the closed loop and looped back on itself at the closed loop such that the line is secured to the winding at the closed loop and is freely slideable through the closed loop. If necessary, this stent can be readily removed from the body lumen after implantation or left in the body lumen as a permanent implant. |
