Abstract:
Various embodiments disclosed relate to drug-coated balloon catheters for treating strictures in body lumens and methods of using the same. A drug-coated balloon catheter for delivering a therapeutic agent to a target site of a body lumen stricture includes an elongated balloon having a main diameter. The balloon catheter includes a coating layer overlying an exterior surface of the balloon. The coating layer includes one or more water-soluble additives and an initial drug load of a therapeutic agent.

Claim (Index 10):
A method for treating a body lumen stricture, the method comprising:\n inserting a balloon catheter into a target site in the body lumen stricture, the balloon catheter comprising\n an elongated balloon having a main diameter, wherein the elongated balloon has a length of about 20 mm to about 160 mm, and \n a coating layer overlying an exterior surface of the balloon, wherein the coating layer comprises one or more water-soluble additives and an initial drug load of a therapeutic agent; \n inflating the balloon until the coating layer contacts walls of the body lumen at the target site and the balloon achieves an inflated balloon diameter for an inflation period, wherein\n a) the ratio of the inflated balloon diameter to a normative body lumen diameter at the target site is about 1.0 to about 20, or \n b) the inflating comprises inflating the balloon to a pressure equal to or greater than a nominal pressure of the balloon catheter, and the stretch ratio of a nominal diameter of the balloon catheter to a normative body lumen diameter at the target site is about 1.0 to about 20, or \n c) the inflating comprises inflating to a pressure greater than the nominal pressure of the balloon catheter, and the nominal diameter of the balloon catheter is less than the inflated balloon diameter, or \n d) any combination of (a); (b), and (c); \n deflating the balloon after the inflation period; and withdrawing the balloon catheter from the body lumen.
