Abstract

Método de tratamiento para la elaboración de implantes o de prótesis de polímeros con liberación controlada de principios activos que comprende una primera etapa denominada " de tratamiento previo ", seguida por una etapa denominada "de impregnación" de los implantes o prótesis de polímeros tratados previamente con principios activos, comprendiendo la primera etapa: - la introducción de los implantes o prótesis de polímeros en una celda a alta presión o autoclave, - la alimentación de la celda con CO2 en una fase de presurización y de calentamiento que sigue una cinética controlada con una tasa de presurización comprendida entre 0,01 y 1 MPa/min, hasta alcanzar condiciones supercríticas o subcríticas líquidas del CO2, con una presión comprende entre 5 y 20 MPa y una temperatura entre 20 ºC y 50 ºC, - una fase de puesta en contacto de los implantes o prótesis de polímeros con el CO2 en modo discontinuo o en modo continuo, comprendiendo la fase de puesta en contacto: * en el modo discontinuo: el aislamiento de la celda a alta presión o autoclave durante un periodo de tiempo de varios minutos a una hora, y * en el modo continuo: el arrastre de la celda a alta presión o autoclave por un flujo de cruce de CO2 durante un período de tiempo que varía de varios minutos a 1 hora, estando el caudal de CO2 comprendido entre un intervalo de caudales que varían de varios gramos por hora a 1 Kg/h, y una fase de despresurización que sigue una cinética controlada con una tasa de despresurización comprendida entre 0,01 y 1 MPa/min, en condiciones isotermas.
