Abstract
Method for reversible sterilization of females in which caps are placed over the fimbriated ends of the Fallopian tubes and sutured to the serosa. The caps block passage of sperm and ova to prevent pregnancy. The caps can be sutured to and removed from the ends of the Fallopian tubes without damage to the transport mechanism inside.
Claims3
The method of temporarily and reversibly obstructing and blocking the interior of the Fallopian tubes of a human female comprising the steps of:
- a. gaining access to the ends of the Fallopian tubes by lower abdominal incision,
- b. placing over the fimbriated end of each of the tubes a cap of inert, medical grade elastomeric material which is light and flexible, and
- c. suturing said cap to the serosa of the tube such that access to and egress from the end of the tube interior is prevented, and such that said cap and said suturing do not interfer with, damage or injure the sperm and ovum transport capability of the interior of the tubes.
A method of temporarily and reversibly capping the ends of the Fallopian tubes of a human female for reversible sterilization, comprising:
- gaining access to the ends of the Fallopian tubes by incision,
- capping the fimbriated ends of the Fallopian tubes with a cap of inert, medical grade, flexible, elastomeric material, and
- suturing the cap around the tubes so that the cap encloses the fimbriated end of the tubes and provides an impervious barrier to the passage of sperm and ova therethrough without interfering with the perastolsis action of the ciliated cells of the Fallopian tubes.
