Cancer treatment method
First Claim
1. A method for in situ treatment of a kidney of a living body having a disease or tumor comprising:
- a) subjecting a kidney of a living body having a disease or tumor to an effective amount of a therapeutic agent by infusion of said agent via blood entering the kidney;
b) creating an isolated section in a major vein spanning the area where the tributory veins connect with the major vein, the major vein and the tributory veins being directly associated with the kidney;
c) passing contaminated effluent blood from the tributory veins of the kidney to said isolated section and capturing said effluent blood therein;
d) concurrently maintaining a continuous flow of blood through the major vein by directing said blood flow through a shunt in the major vein which shunt by-passes said isolated section; and
, e) evacuating said captured blood from said isolated section without exposing said contaminated effluent blood to other organs or tissues of the living body and without interrupting the general blood circulation in the system of the living body.

Abstract
An in situ treatment of an organ, such as a kidney, of a living body, having a disease or tumor. The method includes: subjecting a diseased or tumorous organ, such as a kidney, to an effective amount of a therapeutic agent, by infusing the agent via blood entering the organ, creating an isolated section in a major vein spanning the area where the tributary veins connect with the major vein, the major vein and tributary veins being directly associated with the organ; passing contaminated effluent blood from the tributary veins of the organ to the isolated section and capturing the effluent blood therein; and, evacuating the captured blood from the isolated section without exposing the contaminated effluent blood to other organs or tissues of the body and without interrupting the general circulation in the system of the body.

4. A method for the in situ treatment of a kidney of a living body having a disease or tumor comprising:
-
a) subjecting a kidney of a living body having a disease or tumor to an effective amount of a therapeutic agent by infusion of said agent via blood entering the kidney;
b) inserting a catherer having spaced expandable means in a major vein such that said spaced expandable means creates an isolated section in the major vein spanning the area where the tributory veins connect with the major vein, the major vein and the tributory veins being directly associated with the kidney;
c) passing contaminated effluent blood from the tributory veins of the kidney to said isolated section and capturing said effluent blood therein;
d) concurrently maintaining a continuous flow of blood through the major vein by directing said blood flow through a shunt in the major vein that by-passes said isolated section; and
,e) evacuating said captured blood from said isolated section without exposing said effluent contaminated blood to other organs or tissues of the living body and without interrupting the general blood circulation in the system of the body. - View Dependent Claims (5)

6. A method for in situ treatment of a kidney of a living body having a disease or tumor comprising:
-
a) subjecting a kidney of a living body having a disease or tumor to an effective amount of a therapeutic agent by infusion of said agent via blood entering the kidney, said therapeutic agent being a member selected from the group consisting of IL-2 and biological agents produced from recombinant DNA;
b) inserting a catheter having spaced, expandable means in a major vein such that said spaced expandable means creates an isolated section in the major vein where the tributory veins connect with the major vein, the major vein and the tributory veins being directly associated with the kidney, one of said spaced expandable means preventing said captured blood from flowing to the heart of the living body;
c) passing contaminated effluent blood from the tributory veins of the kidney to said isolated section and capturing said effluent blood therein;
d) concurrently maintaining a continuous flow of blood through the major vein by directing said blood flow through a shunt in the major vein that by-passes said isolated section; and
,e) evacuating said captured blood from said isolated section without exposing said effluent contaminated blood to other organs or tissues of the living body and without interrupting the general blood circulation in the system of the living body.
