A process is provided for coating stents having a first and second surface with passages there between to avoid blockage and bridging of the passages. The process comprises contacting the stent with a liquid coating solution containing a film forming biocompatible polymer under conditions suitable to allow the film forming biocompatible polymer to coat at least one surface of the stent while maintaining a fluid flow through said passages sufficient prevent the film forming biocompatible polymer from substantially blocking said passages. Also described are stents coated by this process.

[ We claim:] [1.] A method for coating a stent having an outer surface and inner surface with passages between the outer surface and inner surfaces comprising:(a) contacting the stent with a liquid coating solution containing a film forming biocompatible polymer under conditions suitable to allow the film forming biocompatible polymer to coat at least one surface of the stent;(b) before the coating solution dries creating fluid movement out of the passages of the stent sufficient to prevent the film forming biocompatible polymers from substantially blocking said passages thereafter;(c) drying the stent to provide at least a partially coated stent with a first coating rein said fluid movement is created by contacting a mandrel with the inner surface of the stent and moving the mandrel relative to the stent to prevent bridges from forming in said passages.
