An expandable stent, comprising:
- an implantable stent scaffold having a lumen defined therethrough;
- wherein the implantable stent scaffold comprises a delivery configuration and a deployed configuration;
- wherein the implantable stein scaffold is expandable from the delivery configuration into the deployed configuration;
- wherein the implantable stent scaffold comprises at least one open cell defined along a wall of the implantable stein scaffold;
- wherein the at least one open cell is expandable from a first cell configuration into a second cell configuration by an expansion device introduced therein;
- and
- wherein the implantable stent scaffold is comprised of a bioresorbable polymer characterized by a molecular weight from about 259,000 g/mol to 2,120,000 g/mol and a crystallinity from about 20% to 40%.
