Abstract

UN DISPOSITIVO MEDICO ECOGENICO DESTINADO A SER INTRODUCIDO DENTRO DE UN PACIENTE, COMPRENDE UN MIEMBRO ALARGADO 123, 901, 1003 QUE INCLUYE UN MATERIAL 127,1002 QUE TIENE UNA IMPEDANCIA ACUSTICA DIFERENTE DE LA DEL MEDIO CIRCUNDANTE. PARA REALZAR UNA IMAGEN PRODUCIDA EN RESPUESTA A UN HAZ SONICO PRODUCIDO POR EQUIPO FORMADOR DE IMAGENES, EL MEDIO INCLUYE TEJIDO O FLUIDOS BIOLOGICOS QUE RODEAN AL MIEMBRO, CUANDO SE INTRODUCE EN UN CONDUCTO DEL PACIENTE. EL MIEMBRO ALARGADO 901 PROPORCIONA TAMBIEN UN INTERFAZ 903 QUE INCLUYE LA SUPERFICIE EXTERNA DEL MIEMBRO Y UNA PLURALIDAD DE HENDIDURAS PARCIALMENTE ESFERICAS 905. ALTERNATIVAMENTE, PARTICULAS GENERALMENTE ESFERICAS 1002 SON UNIDAS A LA SUPERFICIE DEL MIEMBRO L003 PARA PRODUCIR LA IMAGEN EN RESPUESTA AL HAZ SONICO. SE UTILIZAN MATERIALES TALES COMO ACERO INOXIDABLE, PLASTICO Y VIDRIO EN LA FABRICACION DEL DISPOSITIVO MEDICO. EL DISPOSITIVO PUEDE INCLUIR TAMBIEN UN MIEMBRO DE CUERPO ECOGENICO QUE INCLUYA UN MATERIAL COMPUESTO CON EL QUE ECOGENICAMENTE PUEDAN FORMARSE IMAGENES EN EL PACIENTE. EL MATERIAL COMPUESTO INCLUYE UN MATERIAL MATRIZ CON PARTICULAS DISCONTINUAS HECHAS DE UN MATERIAL DIFERENTE AL MATERIAL MATRIZ Y EMPOTRADAS EN EL MISMO. SE DESCRIBEN VARIAS PARTICULAS REFLECTORAS DEL SONIDO SIENDO UN TIPO DE PARTICULA UNA MICROESFERA DE VIDRIO DE UNOS 5 MICRONES DE DIAMETRO. EL MATERIAL MATRIZ L25 PUEDE SER UN PLASTICO, Y PUEDE SER FORMADO O EXTRUIDO EN DISPOSITIVOS TALES COMO CATETERES U OTROS DISPOSITIVOS MEDICOS. EL MATERIAL COMPUESTO PUEDE INCLUIR DIFERENTES CANTIDADES DE PARTICULAS REFLECTORAS DEL SONIDO EN VOLUMEN POR CIEN. ADEMAS PUEDE INCLUIRSE EN EL MATERIAL COMPUESTO UN MATERIAL OPACO A LA RADIO, DE MODO QUE PUEDAN FORMARSE IMAGENES DEL DISPOSITIVO MEDICO ULTRASONICAMENTE ASI COMO RADIOGRAFICAMENTE.
