1. A method for treatment of an anastomotic stricture, the method comprising:
providing a balloon catheter such that the balloon catheter is positioned at a target site in a body lumen comprising the anastomotic stricture, the balloon catheter comprising an elongated balloon and a coating layer overlying an exterior surface of the balloon, wherein the coating layer comprises an initial drug load of a therapeutic agent, and wherein the coating layer is flushed or soaked in a solution comprising water or saline;
inflating the balloon at the target site to contact the coating layer with walls of the body lumen at the location of the anastomotic stricture until the balloon achieves an inflated balloon diameter for an inflation period;
deflating the balloon after the inflation period; and
withdrawing the balloon catheter from the body lumen.
