Abstract

RECUBRIMIENTOS Y POLVOS ANTIMICROBIALES Y METODOS PARA FORMARLOS EN DISPOSITIVOS MEDICOS. LOS RECUBRIMIENTOS SE FORMAN PREFERIBLEMENTE DEPOSITANDO UN METAL BIOCOMPATIBLE ANTIMICROBIAL MEDIANTE TECNICAS DE DEPOSICION AL VAPOR PARA PRODUCIR UN DESORDEN ATOMICO EN EL RECUBRIMIENTO DE MANERA QUE SE CONSIGA UNA LIBERACION SOSTENIDA DE IONES DE METAL SUFICIENTE PARA PRODUCIR UN EFECTO ANTIMICROBIAL. LAS CONDICIONES DE DEPOSICION PREFERIDAS PARA CONSEGUIR UN DESORDEN ATOMICO INCLUYEN UNA TEMPERATURA DE SUSTRATO INFERIOR A LA NORMAL, Y UNA O MAS PRESIONES MAYORES A LO NORMAL DE GAS DE TRABAJO, Y UN ANGULO INFERIOR AL NORMAL DE INCIDENCIA DEL FLUJO DE RECUBRIMIENTO. LOS POLVOS ANTIMICROBIALES FORMADOS POR LA DEPOSICION AL VAPOR O ALTERADOS POR EL TRABAJO MECANICO PARA PRODUCIR UN DESORDEN ATOMICO TAMBIEN SE PROPORCIONAN. EL EFECTO ANTIMICROBIAL DE LOS RECUBRIMIENTOS O POLVOS PUEDE SER ADEMAS ACTIVADO O REFORZADO MEDIANTE LA IRRADIACION CON UNA FORMA DE TRANSFERENCIA DE ENERGIA LINEAL BAJA DE RADIACION TAL COMO UNA RADIACION GAMMA. SE DEFINEN MATERIALES DE PLATA ANTIMICROBIALES NUEVOS, CARACTERIZADOS POR TENER UN POTENCIAL DE REPOSO POSITIVO, UN T{SUB,REC}/T{SUB,M} INFERIOR A 0.33, Y UN TAMAÑO DE GRANO INFERIOR A 200 NM. SE PROPORCIONAN MATERIALES NANOCRISTALINOS O DE GRANO FINO ANTIMICROBIAL, JUNTO CON METODOS DE PREPARACION, EN LOS QUE EL METAL ANTIMICROBIAL SI ES DEPOSITADO EN UNA MATRIZ CON ATOMOS O MOLECULAS DE UN MATERIAL DISTINTO TAL COMO OTROS METALES BIOCOMPATIBLES (TA), OXIGENO ATRAPADO O ABSORBIDO, O COMPUESTOS DE METALES ANTIMICROBIALES O METALES BIOCOMPATIBLES (POR EJEMPLO AGO O TAO). LA INVENCION TAMBIEN SE REFIERE A UN METODO PARA PRODUCIR UN EFECTO ANTIMICROBIAL CON METALES DE PLATA QUE FORMAN IONES DE PLATA COMPLEJOS QUE NO SEAN AG{SUP,+}, AG{SUP,2+} Y AG{SUP,3+}.
