Appl. No.:

17/843150

Inventors:

- Plymouth MN, US
Peter Barnett - Shakopee MN, US
David Hendrickson - Coon Rapids MN, US

International Classification:

A61L 29/08
A61M 25/10
A61L 29/16
A61L 29/06
A61M 29/02

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.

Abstract:

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.

International Classification:

A61M 25/10
A61L 29/16

Abstract:

A balloon catheter 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; the ballon catheter comprising: An elongated balloon; a coating layer overlying an exterior surface of the balloon wherein the coating layer includes one or more water-soluble additives and an initial drug load of a therapeutic agent; and a length-control mechanism () which stretches and elongates the balloon during deflation, giving the balloon a smaller cross-sectional deflated profile for tracking through the body lumen and for removal after treatment.
