ABSTRACT:
The extra-amniotic device has an elongated, flexible tube capable of insertion through the cervix and into the extra-amniotic space of an impregnated uterus. A pair of resiliently flexible flanges are secured to said tube and spaced from each other so that the inner flange can be located within the uterus adjacent the internal os when the outer flange is located within the birth canal adjacent the external os. A resiliently flexible, substantially cylindrical member surrounds the tube between said flanges and is secured to said tube at the opposite axial ends thereof in an air-tight manner. Said member is connected to conduit means which can extend through part of the cervix and the birth canal for connection to a source of fluid under pressure whereby said member is inflated. The outer end of said tube is connected by conduit means to a source of liquid, which may be a medication.
