The invention relates to a method for preparing a composite material
having a homogeneous composition, containing at least one bioactive
ceramic phase and at least one bioresorbable polymer. The inventive
method is characterised in that it comprises the following steps: a) a
bioactive ceramic phase in powder form is obtained, b) the bioactive
ceramic powder is suspended in a solvent, c) a bioresorbable polymer is
added to the suspension obtained in (b) and mixed to produce a viscous
homogeneous dispersion of said bioactive ceramic powder in a solution
formed by the solvent and the polymer, and d) the dispersion obtained in
(c) is precipitated in an aqueous solution in order to obtain a
homogeneous composite material. The invention also relates to the
resulting composite material and to the use thereof in the production of
implantable medical devices.
