Abstract

In a sterilization method a plethora of magnetizable metal particles are deposited into a uterus of a living female organism. Subsequently, a magnet is placed near an external skin surface of the female organism near the uterus to thereby cause at least some of the metal particles to embed in a myometrium or endometrium of the uterus. The metal particles may be magnetized prior to deposition in the uterus. The particles are advantageously formed to have a sharp end which easily penetrates into the uterine lining. Each particle is magnetized so that the sharp end has a predetermined magnetic pole, whereby a magnet with the opposite pole placed against the organism results in an embedding of the sharp end in the uterine lining. In addition, microwave radiation is optionally transmitted into the female organism in a region about the uterus after the embedding of the metal particles in the myometrium or endometrium.

Claims

1. A sterilization method comprising:

depositing a plethora of magnetizable metal particles into a uterus of a living female organism; and

placing a magnet near an external skin surface of the female organism near said uterus to thereby cause at least some of said metal particles to embed in a lining or myometrium of said uterus.

2. The method defined in claim 1 wherein the depositing of said metal particles includes inserting a tubular member through a cervix of the female organism and injecting said metal particles through said tubular member.

3. The method defined in claim 2 wherein said metal particles are suspended in a flowable matrix, the depositing of said metal particles in said uterus including exerting pressure on said flowable matrix to cause said flowable matrix with the suspended metal particles to flow into said uterus.

4. The method defined in claim 3 wherein said tubular member is provided with a balloon, further comprising inflating said balloon after inserting said tubular member through said cervix and prior to injecting of said metal particles through said tubular member, thereby closing said uterus prior to the depositing of said metal particles into said uterus.

5. The method defined in claim 1 wherein said metal particles are suspended in a flowable matrix, the depositing of said metal particles in said uterus including exerting pressure on said flowable matrix to cause said flowable matrix with the suspended metal particles to flow into said uterus.

6. The method defined in claim 1 wherein particles are magnetized prior to the depositing of said metal particles in said uterus.

7. The method defined in claim 1, further comprising emitting microwave radiation into the female organism in a region about said uterus after the embedding of said metal particles in said lining or myometrium.

8. The method defined in claim 1 wherein said metal particles are coated with a biological irritant composition to cause scarring of said lining or myometrium after embedding of said metal particles in said lining or myometrium.

9. A medical treatment method comprising:

depositing a plethora of magnetizable metal particles into internal tissues of a living organism; and

emitting microwave radiation into the organism in a region about said internal tissues after the depositing of said metal particles in said internal tissues.

10. The method defined in claim 9 wherein the internal tissues are a lining, the depositing of said metal particles including:

inserting a tubular member through a skin surface of the organism and into a cavity defined or surrounded by said lining; and

filling said cavity with a solution or suspension containing said metal particles.

11. The method defined in claim 10 wherein said lining is a peritoneal lining, said cavity being a peritoneal cavity.

12. The method defined in claim 9 wherein the internal tissues are a tumorous growth, the depositing of said metal particles including:

inserting a hypodermic needle through a skin surface of the organism and into said tumorous growth; and

injecting said metal particles through said needle into said tumorous growth.

13. The method defined in claim 9 wherein said internal tissues are an aneurysm.

14. The method defined in claim 9 wherein said metal particles are suspended in a flowable matrix, the depositing of said metal particles in said internal tissues including exerting pressure on said flowable matrix to cause said flowable matrix with the suspended metal particles to flow into said internal tissues.

15. The method defined in claim 9 wherein particles are magnetized prior to the depositing of said metal particles in said internal tissues.

16. The method defined in claim 9 wherein said metal particles are coated with a biological irritant composition.

17. A sterilization method comprising:

inserting a tubular member through a cervix of a female organism;

thereafter injecting a sclerosing agent into a uterus of the female organism through said tubular member, said sclerosing agent including a plethora of metal particles; and

acting on said metal particles to embed said metal particles in a lining or myometrium of said uterus.

18. The method defined in claim 17 wherein the acting on said metal particles includes orienting said particles.

19. The method defined in claim 18 wherein the orienting of said metal particles includes applying a magnetic field to said metal particles.

20. The method defined in claim 17, further comprising emitting microwave radiation into the female organism in a region about said uterus after the injecting of said metal particles into said uterus.

21. The method defined in claim 17 wherein said tubular member is provided with a balloon, further comprising inflating said balloon after inserting said tubular member through said cervix and prior to injecting of said sclerosing agent through said tubular member, thereby closing said uterus prior to the injecting of said sclerosing agent into said uterus.
