Abstract

Mounted on the catheter is an endoprosthesis which can be inserted into a vessel, for example, in a predetermined position, radially expandable, implantable at the expansion site, where it is subsequently retained in place. The endoprosthesis can encompass a section of the catheter by its own radial tension and can thereby be retained in an essentially fixed position, without axial play, while its separation from the catheter is effected by radial expansion during implantation. The endoprosthesis may, however, also be mounted on the catheter in an essentailly fixed position, without axial play, by mechanical means ceasing to be effective after the implantation because of radial expansion, or which can be eliminated after the implantation so as to enable the catheter to be withdrawn.
