Abstract

DISPOSITIVOS DE FOTODIODOS MICROSCOPICOS (10) CON ELECTRODOS DE SUPERFICIE SEMITRANSPARENTE, SON COMBINADOS CON UN LIQUIDO U OTRO VEHICULO APROPIADO E INYECTADOS EN EL ESPACIO SUBRETINAL PARA TRANSDUCIR LUZ INCIDENTE EN CORRIENTE ELECTRICA QUE ESTIMULA LAS CAPAS CELULARES QUE CUBREN LA RETINA. LOS DISPOSITIVOS PUEDEN SER MICROESFERAS, MICROCILINDROS U OTROS. UNA CAPA FERROMAGNETICA ENTERRADA DE MANERA DESCENTRADA CONFERIRA UNA SUSCEPTIBILIDAD MAGNETICA A LOS DISPOSITIVOS Y UN CAMPO MAGNETICO APLICADO, LAS ALINEARA CON EL ESPACIO SUBRETINAL, DIRIGIENDO SUS SUPERFICIES FOTOACTIVAS HACIA LA LUZ INCIDENTE. ALTERNATIVAMENTE, PUEDEN ESTAR ENTERRADAS, PREALINEADAS, EN UNA LAMINA FLEXIBLE TRANSPARENTE (122), PERMEABLE A NUTRIENTES Y OXIGENO ANTES DE LA IMPLANTACION EN UN ESPACIO SUBRETINAL. LA LAMINA SE DISOLVERA DEJANDO UNIDADES SEPARADAS DE FORMA DETERMINADA. LOS DISPOSITIVOS PUEDEN SER DEL TIPO PIN O NIP O UNA COMBINACION DE LOS DOS. UNA CAPA CAPACITADORA ELECTRICA (146), TAMBIEN PUEDE SER INCORPORADA AL DISPOSITIVO PARA PERMITIR EL ALMACENAMIENTO DE CARGA DURANTE LA EXPOSICION A LA LUZ, Y LA LIBERACION DE CARGA EN LA OSCURIDAD PRODUCIENDO UNA CORRIENTE DE POLARIDAD OPUESTA.
