Abstract

UN APARATO ULTRASONICO (10) Y UN METODO PARA ACOPLAR UNA ENERGIA ULTRASONICA EN LAS PAREDES INTRAVASCULARES Y ASI AUMENTAR LA FONOFORESIS Y PARA LA DISOLUCION DE BLOQUEOS INTRAVASCULARES. EL APARATO (10) INCLUYE UN RADIADOR (44) PARA ACOPLAR ONDAS ULTRASONICAS Y UN CRISTAL PIEZOELECTRICO (24), CONECTADO A DICHO RADIADOR (44), PARA LA GENERACION INTRAVASCULAR DE ONDAS ULTRASONICAS; EN DONDE DICHAS ONDAS ULTRASONICAS SE PROPAGAN A LO LARGO DE UN EJE LONGITUDINAL (104) DE DICHO CRISTAL PIEZOELECTRICO (24). SE INTRODUCE UN LIQUIDO GERMINAL CERCA DEL RADIADOR PARA FOMENTAR LA CAVITACION DEL FLUIDO INTRAVASCULAR. ADEMAS SE AUMENTA SIGNIFICATIVAMENTE LA DISOLUCION DE LOS BLOQUEOS INTRAVASCULARES Y LA INHIBICION DE LA REESTENOSIS MEDIANTE AGENTES QUIMICOS CUANDO SE COMBINAN CON UNA ENERGIA ULTRASONICA.
