ABSTRACT:
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) 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.
