Abstract A support body to be inserted in the uterus is connected to inflatable occluding members intended and adapted solely to seal the mouths of the Fallopian tubes when inflated. Because there is no pressure contact between the device and the walls of the uterus proper, there is no impediment to the flow of menstrual blood nor any risk of harmful effects caused by pressure. The support body comprises a central piece through which an inflation medium can be introduced into the occluding members, which are disposed at the ends of two branches projecting laterally from the central piece. Thus, the device is easy to position accurately within the uterus. The support body is stiff but resiliently deformable and of stable shape.
An intrauterine contraceptive device comprising a hollow support body of stable shape made of stiff but resiliently deformable material, said support body including a central portion and two branch portions projecting laterally from said central portion, and two inflatable members respectively disposed at the ends of said branch portions remote from said central portion, said inflatable members being inflated by introducing a pressure medium into said central portion of said support body and assuming a spherical shape upon inflation within the uterus and being adapted when in operative position to seal the mouths of the Fallopian tubes without pressure contact between said device and the walls of the uterus proper.
