<p>A process for forming biocompatible porous matrices of bioabsorbable materials comprising: a) providing a bioabsorbable polymer; b) dissolving the bioabsorbable polymer in a volumetric orientation aid to yield a molten solution; c) solidifying the molten solution to yield an orientation matrix comprising first and second phases, the first phase being the bioabsorbable polymer and the second phase being the volumetric orientation aid; and d) the removing of the volumetric orientation aid from the solid orientation matrix; to yield a biocompatible matrix of bioabsorbable polymer. Also matrices formed by the process and devices made with such matrices.</p> |
