A method for preventing and treating internal infections, e.g., urinary tract infections, caused by catheters is provided, in particular by reduction in catheter-associated biofilms. A coating composition is used to treat the catheter and applied through the catheter into the bladder or other body urinary tract organ to kill or neutralize microorganisms, including biofilms therein. The composition comprises a humectant and an antimicrobial with the antimicrobial including a monoquaternary ammonium compound or pharmaceutically acceptable salt thereof. The coating layer has antimicrobial cidal or static activity for at least about one hour.

Various embodiments disclosed relate to drug-coated balloon catheters for treating, preventing, or reducing the recurrence of a stricture and/or cancer, or for treating benign prostatic hyperplasia (BPH), in a non-vascular body lumen 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. In some embodiments, the balloon catheter includes a length-control mechanism which stretches and elongates the balloon when it is in a deflated state, giving the balloon a smaller cross-sectional deflated profile for tracking through the body lumen and for removal after treatment.

The present invention relates to a catheter device comprising at least one pharmaceutically active compound, wherein the device is capable of releasing said pharmaceutically active compound such as angiogenesis promoting factors, inhibitors of an angiogenesis inhibiting factor or antibiotics over an extended period. It is preferred that the device is tubular and longitudinally extending device assembly with an intraluminal and an extraluminal segment and a proximal and a distal end, wherein the intraluminal segment comprises at least one reversibly expandable portion. Also envisaged is a catheter device for use in preventing a slow-healing or non-healing wound, diabetic foot or intoxication with bacterial toxins, or for treating or preventing bacterial or virus infections and/or medical complications during transplantation.
