Abstract

Methods for controlling the release rate and improving the mechanical properties of a stent coating are disclosed.

Claims

exact text as granted — not AI-modified
1 . A method comprising:
 exposing a stent coated with paclitaxel and SIBS to either (1) electron beam radiation or (2) gamma radiation in the presence of oxygen, wherein the radiation acts to decrease the degree of cross-linking of the SIBS, thereby providing a means for controlling the paclitaxel release rate and improving the mechanical properties of the coating.   
     
     
         2 . The method of  claim 1 , wherein the exposure is to electron beam radiation. 
     
     
         3 . The method of  claim 1 , wherein the exposure is to gamma radiation.
