Patent ID: 8632847

Claim:
A method of making a stent comprising: providing a stent including a bioresorbable polymer scaffold and a bioresorbable polymer coating over at least a portion of the scaffold; disposing the stent over a tubular mandrel such that a lumenal surface of the stent faces a surface of the mandrel, wherein the surface of the mandrel has a plurality of grooves aligned longitudinally; and radially compressing the stent over the surface of the mandrel such that the grooves at the surface of the mandrel form grooves on the lumenal surface of the stent, wherein the grooves on the luminal surface are aligned along a cylindrical axis of the stent further comprising disposing the stent over the mandrel into a sliding wedge crimper, wherein the crimper applies pressure to the stent to radially compress the stent over the surface of the mandrel.
