<p>A process for cervical dilation prior to the performance of an abortion comprising the steps of inserting an abortion facilitator unit through the cervix and extending into the uterine cavity, gradually, uniformly radially expanding the portion of the dilator adjacent to the cervix at a controlled rate to dilate the cervix by introduction of a fluid, removing the fluid once the cervix has been dilated, removing the dilating unit, and completing the abortion. Apparatus for cervical dilation comprising a shaft member having three conduits extending therethrough, one conduit terminating substantially inboard the distal end and communicating with a dilating section of substantially cylindrical configuration when expanded, a second conduit terminating distal of said first conduit and terminating in an expandable anchoring member, and said third conduit terminating proximate the tip of said shaft member for permitting ingress and egress of fluids to the uterine cavity.</p> |
