Method and apparatus for non-surgically sterilizing female reproductive organs
First Claim
1. An ostial occlusion device for forming an hermetic seal around the tubal ostium of the female reproductive system comprising:
- a. a hub fabricated from a rigid, non-porous material including a circumferential edge and an upper surface and a lower surface;
b. means fabricated from a rigid, non-porous material oriented perpendicular to and extending outward from the lower surface of the hub insertable into the uterotubal junction of the female reproductive system for centering the nub about the tubal ostium; and
c. a ring of porous material surrounding the circumferential edge of the hub and including an exposed lower surface for contacting the tissue surrounding but not including the tubal ostium and for receiving fibroblast ingrowth to create an hermetic seal surrounding but not including the tubal ostium to provide fluid isolation between the fallopian tube and the uterine cavity to thereby render the female reproductive system infertile,whereby the non-porous lower surface of the hub extends radially outward from the hub centering means over the tissue immediately adjacent to the tubal ostium to prevent fibroblast ingrowth into said tissue.

Abstract
An ostial occlusion device forms an hermetic seal around the tubal ostium of the uterotubal junction and includes a hub fabricated from a non-porous material having a circumferential edge and upper and lower surfaces. A locator pin is oriented perpendicular to and extends outward from the lower surface of the hub and is insertable into the fallopian tube at the uterotubal junction to center the hub about the tubal ostium. A ring of porous material surrounds the circumferential edge of the hub and includes an exposed lower surface which contacts the tissue surrounding the tubal ostium and receives fibroblast ingrowth to create an hermetic seal around the tubal ostium. This hermetic seal isolates the fallopian tube from the uterine cavity and renders the female reproductive system infertile.

19. A method for forming an hermetic seal at the junction between the fallopian tube and the uterine cavity of the female reproductive system to render a female infertile, comprising the steps of:
-
a. introducing an ostial occlusion device through the vagina and cervix into the uterine cavity, the ostial occlusion device including (1) a hub having a circumferential edge and upper and lower surfaces;
(2) hub centering means extending outward from the lower surface of the hub; and
(3) a ring of porous material surrounding the circumferential edge of the hub and including an exposed lower surface;b. inserting the hub centering means of the ostial occlusion device into the uterotubal junction until the exposed lower surface of the ring of porous material contacts the tissue surrounding the tubal ostium area of the uterotubal junction; and c. maintaining the lower surface of the ring of porous material in contact with the tissue surrounding the uterotubal junction until fibroblast ingrowth into the porous material commences. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
