Abstract
A luminal endoprosthesis comprising a framework made up of braided filaments. The framework is self-expanding, that is to say that after it has been radially compressed for positioning of the endoprosthesis, it automatically recovers its nominal diameter. The metal of the framework has undergone a thermal treatment bringing about a state transition, at a temperature close to that of the organism, and this confers upon it a suitable rigidity after it has been positioned in an anatomical conduit.
