A delivery device for delivering an implantable endoprosthesis with an occlusion region for occluding fluid flow to a desired location in a body lumen. The delivery device includes an outer sleeve and an inner tube terminating at a distal tip. The distal tip is made of one of a dissolvable, bioabsorbable, or deformable material. Upon deployment of the endoprosthesis at the desired location, the shape of the distal tip is altered to a different shape and withdrawn through the constricted region of the endoprosthesis. |
