Abstract: The present invention provides a process for preparing a porous bioresorbable material having interconnected pores. A bioresorbable polymer and a low molecular weight oligomer are dissolved in an organic solvent to form a bioresorbable polymer solution. The bioresorbable polymer has a molecular weight greater than 20,000 and the oligomer has a molecular weight of 200 to 4000. The bioresorbable polymer solution is then contacted with a coagulant to form a porous bioresorbable material.
