Abstract
La presente invención se refiere a métodos para hacermateriales bioabsorbibles que tienen poros de interconexión, caracterizados porque comprenden los pasos de: proveer una dispersión de un polímero bioabsorbible en un primer solvente; añadir partículas de un segundo material a la dispersión, seguido por la congelación de la dispersión para formar una dispersión congelada teniendo las partículas embebidas en la misma, y remover dichos primer solventes y segundo material de dicha dispersión congelada en un solo paso mediante secado por congelación o secado por solvente.Material de implante bioabsorbible poroso que se obtiene mediante un procedimiento objeto de la presente invención. Uso del material bioabsorbible poroso descrito, para la preparación de un implante o vendaje para el tratamiento de las heridas.The present invention relates to methods for making bioabsorbable materials having interconnecting pores, characterized in that they comprise the steps of: providing a dispersion of a bioabsorbable polymer in a first solvent; adding particles of a second material to the dispersion, followed by freezing the dispersion to form a frozen dispersion having the particles embedded therein, and removing said first solvents and second material from said frozen dispersion in one step by freeze drying or solvent drying. Porous bioabsorbable implant material obtained by a process object of the present invention. Use of the porous bioabsorbable material described, for the preparation of an implant or bandage for the treatment of wounds.
