摘要：

A method of laser machining a polymer construct to form a stent that includes a bioresorbable polymer and an absorber that increases absorption of laser energy during laser machining. The laser cuts the tubing at least in part by a multiphoton absorption mechanism and the polymer and absorber have a very low absorbance or are transparent to light at the laser wavelength.
