Abstract

LA INVENCION SUMINISTRA UN CATETER DE LUMEN DOBLE (20) QUE COMPRENDE MATERIALES EN FORMA DE TUBO EXTERIOR E INTERIOR (28, 30). UNA PARTE PRINCIPAL (22) SE EXTIENDE AXIALMENTE Y TIENE UNA PRIMERA SECCION DE CORTE SELECCIONADA E INCLUYE PARTES PRINCIPALES DE LOS MATERIALES RESPECTIVOS EN FORMA DE TUBO EXTERIOR E INTERIOR QUE JUNTOS DEFINEN UN LUMEN DE ENTRADA ANULAR (32) Y UNA PARTE PRINCIPAL DE UN LUMEN DE RETORNO (34) CONTENIDO DENTRO DEL LUMEN DE ENTRADA. UNA PARTE DE TRANSICION (67) ESTA CONSTRUIDA INTEGRAMENTE DE AMBOS MATERIALES EN FORMA DE TUBO EXTERIOR E INTERIOR Y TIENE UNA SEGUNDA SECCION DE CORTE MAS PEQUEÑA QUE LA PRIMERA SECCION DE CORTE. LA PARTE DE TRANSICION SE EXTIENDE AXIALMENTE DESDE EL EXTREMO DISTAL DE LA PARTE PRINCIPAL Y ESTA PUEDE EXTENDERSE HASTA INCLUIR UNA PARTE DE PUNTA (65) CONSTRUIDA SOLAMENTE DEL MATERIAL DE TUBO EXTERIOR Y QUE SE EXTIENDE AXIALMENTE DESDE LA PARTE DE TRANSICION. LA PARTE DE TRANSICION POR SI MISMA, O CON LA PARTE DE LA PUNTA, DEFINE UNA SECCIONDE PUNTA (26) QUE ES UNA CONTINUACION DE LA PARTE PRINCIPAL DEL LUMEN DE RETORNO PARA COMPLETAR EL LUMEN DE RETORNO. TAMBIEN SE PRESENTA UN METODO DE MANUFACTURACION DEL CATETER.
