Abstract:
1. Process for manufacturing a porous coating on a medical implant with structures in the micro- or nano-size domain consisting of the following steps: providing a support having a surface, depositing on the surface one mono-layer of temporary particles, depositing a coating on the temporary particles such that the thickness of the coating is less than the particle diameter, eliminating the temporary particles and thereby obtaining a porous coating containing pores, the pores of the porous coating corresponding to spaces previously occupied by the temporary particles and at least a part of the pores communicating with an external environment in a vertical direction from the surface, employing a fixation step of the porous coating, loading the implant by filling the pores at least partially with one or more drugs, bone growth factors, resorbable bioactive ceramics, bone cells or other cells.
