  • Patent number: 7721739
    Abstract: Apparatus for preventing fluid transfer through an opening connecting an oviduct to a uterine cavity includes a body having a base with a periphery and a seal carried by the body for overlying and engaging uterine tissue leading to the opening. The seal receives fibroblast in-growth to create a hermetic seal between the oviduct and the uterine cavity. A peripheral anchor portion extends from the base for securing the body to the uterine tissue leading to the opening, the base overlying the opening.
    Type: Grant
    Filed: August 13, 2007
    Date of Patent: May 25, 2010

  • Patent number: 6371118
    Abstract: Apparatus for preventing fluid transfer through an opening between an oviduct and a uterine cavity including an insert for insertion into the oviduct through the opening, the insert having a first portion for causing fibroblast ingrowth and a second portion including a biodegradable anchor for securing the insert to the oviduct.

  • Patent number: 6286510
    Abstract: Apparatus for preventing fluid transfer through an opening connecting an oviduct to a uterine cavity comprising an insert for insertion into the oviduct through the opening leading from the uterine cavity to the oviduct, a seal carried by the insert for engaging uterine tissue leading to the opening and receiving fibroblast ingrowth to create a hermetic seal between the oviduct and the uterine cavity, and an engagement element supported by the insert for securing the insert to the oviduct.

  • Patent number: 4606336
    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.
