Abstract
A stent having a stent body made from a crosslinked bioabsorbable polymer is disclosed. A method of making the stent including exposing a tube formed from a bioabsorbable polymer to radiation to crosslink the bioabsorbable polymer and forming a stent body from the exposed tube is disclosed. The tube can include a crosslinking agent which induces crosslinking upon radiation exposure. Additionally or alternatively, the bioabsorbable polymer can be a copolymer that crosslinks upon exposure to radiation in the absence of a crosslinking agent.
