Abstract

Un stent comprende en principio una estructura tubular (1) conformada por una pared envolvente definida por una armadura de malla pudiendo adoptar una posición plegada para introducirse dentro de un conducto tubular (2) y una segunda posición desplegada para instalarse dentro de tal conducto tubular. Se caracteriza porque: la estructura tubular comprende una configuración tronco-cónica al menos en la posición desplegada; la estructura tubular integra unos tramos longitudinales (3) correspondientes con las generatrices de la citada configuración tronco-cónica, y al menos dos anillos (4) de trayectoria circunferencial de diferente diámetro unidos a los tramos longitudinales (3); los anillos de trayectoria circunferencial integran en la posición plegada, unos dobleces (6) contenidos en la superficie envolvente de la estructura tubular.
