Abstract

SE TRATA DE UN DISPOSITIVO DE FILTRACION SANGUINEA IMPLANTABLE EN EL CUERPO DE UN PACIENTE, TENIENDO UN CATETER (3) Y UN FILTRO SANGUINEO (7), FIJO A UN EXTREMO DEL CATETER, MANTENIENDO ABIERTO ESTE EXTREMO. CONFORME A LA INVENCION, ESTE CATETER TIENE UNA RIGIDEZ VARIABLE, SIENDO MAS RIGIDO DEL LADO DE SU EXTREMO (3B), DONDE SE FIJA EL FILTRO, Y MAS FLEXIBLE DEL LADO OPUESTO (3A), DONDE EL CATETER PUEDE CONECTARSE A UNA CAMARA IMPLANTABLE (5), OBTENIENDOSE ESTA RIGIDEZ RELATIVA MEDIANTE LA ACCION DE PONERSE RIGIDA LA PARED DEL CATETER, EN EL EXTERIOR DE SU CITADO CONDUCTO INTERNO, QUE SE MANTIENE ASI LIBRE. PARA OBTENER ESTA RIGIDEZ, SE PUEDE RECURRIR A MEDIOS ANEXOS DE OBTENCION DE LA RIGIDEZ, EMBUTIDOS EN LA PARED DEL CATETER. APLICACION EN ESPECIAL A LOS TRATAMIENTOS VASCULARES POR TROMBOLISIS.
