Abstract

With an insertion catheter for inserting a vascular prosthesis into a vessel, with an elongate, substantially tubular catheter cover having a proximal and a distal end, with an outlet for the vascular prosthesis provided at the distal end, in order to make insertion of the vascular prosthesis into the vessel particularly safe and simple, in particular, to provide the vascular prosthesis with protection against twisting, it is proposed that the outlet have a cross-sectional shape differing from a circular shape, and that the cross-sectional area defined by the outlet area be smaller than the cross-sectional area of the vascular prosthesis inserted in the vessel in the opened, unexpanded state.
