Claim Text:
1. A biodegradable stent comprising: a scaffold including struts comprising a poly(L-lactide)-based biodegradable polymer, wherein the struts have a luminal surface and an abluminal surface, wherein the polymer has induced polymer orientation in a circumferential direction, and wherein the induced polymer orientation decreases from the luminal surface to the abluminal surface of the struts, wherein the polymer has the induced polymer orientation in a radial section between the luminal surface and a transition radial distance and no induced polymer orientation between the transition radial distance and the abluminal surface, and wherein the transition radial distance is ⅓ to ½ of a radial thickness of the struts.
