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 23):
A method of splitting an enlarged prostate or creating a commissurotomy for treating benign prostate hyperplasia comprising:\n inserting an uncoated balloon catheter sheath assembly and a scope; removing the sheath from over the balloon and inflating the balloon at a target site in the prostate until the pressure drops, the prostatic tissue yields and the commissurotomy is created; increasing the pressure further to dilate the prostate more; keeping the balloon inflated for 1 minute to 7 days; deflating the uncoated balloon catheter; withdrawing the uncoated balloon catheter assembly from the body lumen; inserting a drug coated balloon catheter sheath assembly, where in the balloon comprises at least one neck section on the balloon comprising a smaller diameter than the main diameter when the balloon is inflated, the at least one neck section dividing the balloon into at least two main sections each having a diameter; positioning the scope and drug coated balloon catheter near the external sphincter; removing the sheath from over the drug coated balloon and slowly inflating to dilate the prostate more; and keeping the balloon inflated for 1 minute to 7 days to release the drug into tissue and to prevent bleeding, 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).
