Medicated or unmedicated, absorbable/biodegradable, polymeric tubular stents for temporary placement in body lumens maintain patency and provide dimensional stability at the biological site. The stent design is based on a radially fluted, tubular form having grooves or flutes along its entire length for expansion to a predetermined diameter after deployment, using a balloon catheter, into a tubular body lumen through outward deformation of the fluted wall. |
