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.

A process for preparing a porous bioresorbable material having interconnected pores, comprising the following steps:
- dissolving a bioresorbable polymer and a low molecular weight oligomer in an organic solvent to form a bioresorbable polymer solution, wherein the bioresorbable polymer has a molecular weight greater than 20,000, and the oligomer has a molecular weight of 200 to 4000;
- and
- contacting the bioresorbable polymer solution with a coagulant to form the porous bioresorbable material, wherein the low molecular weight oligomer is soluble in the coagulant, and the bioresorbable polymer is insoluble in the coagulant.
