Virtual stent making process based upon novel enhanced plate tectonics derived from endoluminal mapping
First Claim
1. A Stent for implantation into the internal carotid artery, having a lower end and an upper end , wherein a radius measured from lower end to upper end decreases in value, wherein the stent has a ‘
- trumpet-like’
tectonic structure in the form of angles and curvatures adapted to, and tracking the course of the internal carotid artery and that in the region of the outlet of internal carotid artery, lower end is formed as an ovaloid opening.

Abstract
The present invention concerns a process for making a virtual stent for implantation into a body lumen. A particularly preferred embodiement is optmized for emplacement and indwelling in the internal carotid artery, with a lower end and an upper end wherein the radius decreases from lower end to upper end, and includes ‘trumpet-like’ or parabolic elements abutting facultative 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.

- 2. A Stent for implantation into the internal carotid artery, with a lower end and an upper end, wherein the radius decreases from lower end to upper end, characterized by the fact that stent has a tectonic structure in the form of angles and curvatures adapted to the course of internal carotid artery (4), that lower end projects into the common carotid artery and that an ovaloid recess is provided in the region of the outlet of the external carotid artery.

21. In a stenting apparatus configured to correspond to the endoluminal surface of a carotid artery having a tectonic structure in the form of angles and curvatures following the course of a patient'"'"'s internal carotid artery and having an ovaloid aperture communicating with the external carotid artery, the improvement which comprises a trumpet-like tapered section from proximal to distal ends, whereby the spatial orientation of the stent defines a substantially hyperbolic section adjacent said ovaloid aperture.

24. A Process for generating a virtual stent, comprising the steps of:
-
targeting a luminal surface to be mapped;
capturing a non-contact picture of the surface data of the luminal surface to be mapped;
generating a multiplicity of three-dimensional measuring points;
arraying said multiplicity of three-dimensional measuring points within a predetermined lattice structure defining a tectonic structure in the form of angles and curvatures adapted to the course of the mapped luminal surface;
providing individuated or otherwise customized sections of geometric scaffolding structure corresponding to the portions arrayed in the lattice by three-dimensional computer modeling to make a tectonic structure for a stent.
