Abstract

LA INVENCION SE REFIERE A UN CATETER COAXIAL, DE LUMEN DOBLE (20) QUE TIENE UNA SECCION PRINCIPAL (37), UNA SECCION DE PUNTA (38), Y UNA PARTE PROXIMA EN FORMA DE U (34) QUE SE EXTIENDE DESDE LA SECCION PRINCIPAL Y QUE FINALIZA EN UNA UNION (32) EN LA QUE LOS TUBOS DE ENTRADA Y DE SALIDA (26, 28) ESTAN CONECTADOS A LA PARTE PROXIMA. UN TUBO INTERIOR (48) SE EXTIENDE DESDE LA FUNCION HASTA LA SECCION DE LA PUNTA (38) DEL CATETER PARA DEFINIR UN LUMEN DE RETORNO (52), Y COMBINA CON LOS TUBOS EXTERIORES, RESPECTIVOS (46, 60) EN LA SECCION PRINCIPAL (37) Y EN LA PARTE PROXIMA (34) PARA DEFINIR UN LUMEN DE ENTRADA (50). EL TUBO INTERIOR (48) TIENE LAS PAREDES FINAS CON RELACION AL GROSOR DE LA PARED DEL PRIMER TUBO EXTERIOR (46) USADO EN LA SECCION PRINCIPAL (37), Y UN SEGUNDO TUBO EXTERIOR (60) USADO EN LA PARTE PROXIMA (34) TIENE UN AREA DE SECCION DE CORTE MAYOR QUE EL PRIMER TUBO EXTERIOR. TAMBIEN SE DESCRIBE UNA ESTRUCTURA PROXIMA, FINAL EN LA CUAL LOS TUBOS DE ENTRADA Y DE SALIDA SE EXTIENDEN GENERALMENTE PARALELOS CON EL CUERPO PRINCIPAL Y HACIA UN LADO DEL CUERPO PRINCIPAL.
