The present invention concerns a process for making a virtual stent for implantation into a human lumen. A particularly preferred embodiment is optimized for emplacement and indwelling in the internal carotid artery, with a lower end and an upper end wherein the radius decreases from lower end (11) to upper end (12), and includes 'trumpet-like' or parabolic elements abutting faculative apertures. Generally, computer-aided-design derived stent has a tectonic structure in the form of angles and curvatures adapted to the course of a desired lumen. For example, the internal carotid artery whereby lower end in the region of the outlet of internal carotid artery is formed as an ovaloid recess provided in the region of the outlet of the external carotid artery. |
