Abstract

An absorbable endoluminal stent and method for preparing the same are provided in the present invention. The absorbable endoluminal stent comprises a stent body, a plurality of through holes formed in the stent body, and bioabsorbable polymeric materials filled in the through holes. When the stent is implanted into the blood vessels, damages on stent caused during crimping and expansion processes are reduced. Radical supporting force duration of stent is improved and mechanical properties of stent after implantation are guaranteed by compositing the materials in the through holes and materials of the stent body.
