Multi-function catheter and use thereof
First Claim
1. A catheter for delivering an agent to an area of treatment, the catheter comprising:
- a catheter body;
a balloon assembly coupled to the catheter body, wherein the balloon assembly has spaced-apart balloons that define an area between the balloons;
a first lumen extending along the catheter body to pass an inflation material to the balloons to control an inflation level of the balloons; and
a second lumen extending along the catheter body and having an outlet in the area between the balloons.

Abstract
A catheter for delivering an agent to an area of treatment is presented. The catheter includes a catheter body, a balloon assembly coupled to the catheter body, a first lumen, and a second lumen. The balloon assembly has spaced-apart balloons that define an area between the balloons. The first lumen extends along the catheter body to pass an inflation material to the balloons to control an inflation level of the balloons. The second lumen extends along the catheter body and having an outlet in the area between the balloons. There may be a third lumen for bypassing a biological fluid such as blood while the catheter is being used. The method of using this catheter is also presented. The method entails simultaneously inflating the balloons to isolate a treatment area and adding an agent to the treatment area through one of the lumens.

15. A method of delivering an agent to a treatment area, the method comprising:
-
providing a catheter that is attached to inflatable balloons, the catheter having a first lumen and a second lumen extending along the catheter;
positioning the catheter so that the area of treatment is between the balloons;
simultaneously controlling an inflation level of the balloons to create the treatment area between the balloons, wherein the controlling includes passing an inflation material through the first lumen that has an opening into each of the balloons; and
passing the agent through a second lumen into the treatment area. - View Dependent Claims (16, 17, 18, 19, 20, 21)

39. A catheter for cancer treatment, the catheter comprising:
-
a catheter body having a proximal end and a distal end;
a first balloon positioned to inflate around the proximal end of the flexible catheter body; and
a second balloon positioned to inflate around the distal end of the flexible catheter body;
wherein the flexible catheter body has a first lumen for allowing a fluid to pass across the first and the second balloons, a second lumen for inflating the first balloon and the second balloon, and a third lumen for passing an agent to an outlet between the first balloon and the second balloon.
