Bifurcated stent includes a main stent body and a crown adapted to deploy it laterally into a branch vessel from the main stent body. A therapeutic agent or other material is coated on at least a portion of the crown of the stent, usually over the base of the crown adjacent to the main stent body. The main stent body is either free from coating or is coated in a different manner than is the crown portion of the stent.
