Claim:
1. A method of increasing flow through a wall of a stent, comprising: expanding the stent which defines a lumen therethrough from a delivery configuration into a deployed configuration, wherein the stent has a uniform pattern along its entire length in the delivery configuration; introducing an expansion device into the lumen and through an open cell defined along the wall of the stent; and enlarging the open cell from a first expanded configuration into a second enlarged configuration by isotropically elongating one or more struts of the stent from 2% to 120% without cracking, fracturing, or failing, and wherein the stent is comprised of a bioresorbable polymer characterized by a molecular weight from 259,000 g/mol to 2,120,000 g/mol and a crystallinity from 20% to 40%.
