1. A placement catheter assembly comprising:

  • a hollow outer shaft comprising a distal part, said distal part comprising a distal end;

    an inner shaft, having a distal end, movably housed within the outer shaft;

    a radially-expansible endoluminal prosthesis mounted about the inner shaft between the distal ends of the inner and outer shafts;

    a distal end attachment device comprising a distal end release element carried by the inner shaft and releasably securing the prosthesis to the inner shaft;

    a proximal end attachment device comprising;

    an elongate, tubular proximal end release element holder extending axially away from the distal end of the outer shaft;

    a proximal end release element carried by the outer shaft with a part of the proximal end release element passing through the holder;

    the holder having a side opening from which a portion of the proximal end release element extends to engage the prosthesis thereby releasably securing the prosthesis to the outer shaft; and

    the prosthesis in a radially contracted state and the distal and proximal end release elements together having a maximum diameter which is at most about equal to the diameter of the distal part of the outer shaft so that placement of the prosthesis is facilitated.
