1. A percutaneous, transluminal stent delivery system (50) which comprises a tube (54) having a tube wall with a distal end at the distal end of the system, a proximal end within a proximal zone of the system, a luminal surface and an abluminal surface, the tube defining i) a lumen which extends the full length of the tube, and ii) a distal tip zone which is contiguous with the distal end of the tube, in which tip zone both the luminal (70) surface and the abluminal (72) surface taper radially inwardly with increasing nearness to the distal end (74) of the tube, at least when the distal tip zone is at 37°

  • C. and free from externally imposed hoop stresses; and

    characterized by a device (118) for loading a self-expanding stent into the proximal end of the tube; and

    a device (56) to advance the self-expanding stent constrained from radially-outward expansion by the tube wall all the way from the proximal end of the tube to a distal end zone of the tube.
