Abstract
Stent de alta capacidad de fijacion y contacto endotelial. Comprende un cuerpo tubular (1) compuesto por una sucesion de tramos (2) de elementos esqueléticos (1a), cuyos paramentos exteriores (1b) poseen aristas aguzadas (1d) y depresiones (1c); se describe una forma de realizacion en la que cada tramo (2) está compuesto por hileras (3)(4) de entrantes (9)(10) y salientes parcialmente unidas por primeros puentes (6) de vinculacion y los tramos (2) adyacentes están parcialmente unidos entre sí por segundos puentes (7) de vinculacion; las aristas aguzadas (1d) y las depresiones (1c) pueden extenderse a lo largo de los elementos esqueléticos (1a); la expansion vascular y la capacidad de fijacion aumenta por la penetracion parcial de las aristas aguzadas (1d) en el endotelio (22); la capacidad de contacto aumenta por la superficie de los paramentos exteriores (1b) que son aplicables al conducto vascular (20); esta superficie aumenta con las depresiones (1c) que además son aptas para la transmision de drogas. La presencia de las depresiones (1c) en los paramentos exteriores (1b) permite un avance (22a) del endotelio (22) que aumenta la superficie de contacto. Esto produce una mejor fijacion ulterior del stent dentro del conducto vascular (20) y una liberacion más efectiva de droga en el endotelio (22).High capacity stent fixation and endothelial contact. It comprises a tubular body (1) composed of a succession of sections (2) of skeletal elements (1a), whose outer walls (1b) have sharp edges (1d) and depressions (1c); an embodiment is described in which each section (2) is composed of rows (3) (4) of incoming (9) (10) and outgoing partially joined by first connecting bridges (6) and sections (2) adjacent are partially linked together by second link bridges (7); the sharp edges (1d) and the depressions (1c) can extend along the skeletal elements (1a); vascular expansion and fixation capacity increases due to partial penetration of sharp edges (1d) in the endothelium (22); the contact capacity increases by the surface of the outer walls (1b) that are applicable to the vascular duct (20); This surface increases with depressions (1c) that are also suitable for drug transmission. The presence of depressions (1c) in the outer walls (1b) allows an advance (22a) of the endothelium (22) that increases the contact surface. This produces a better subsequent fixation of the stent within the vascular duct (20) and a more effective release of drug into the endothelium (22).
