Abstract
A process for forming biocompatible porous matrices of bioabsorbable materials comprising: PA1 a) providing a bioabsorbable polymer; PA1 b) dissolving the bioabsorbable polymer in a volumetric orientation aid to yield a molten solution; PA1 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 PA1 d) removing the volumetric orientation aid while the solution is solid; to yield a biocompatible matrix of bioabsorbable polymer. Also matrices formed by the process and devices made with such matrices.
