Abstract: A cervical canal dilator comprising an elongate tubular or cylindrical shaft having a distal end and a proximal end; the interior of the shaft being provided with internal cavities that communicate with anchor and dilation balloons in such a manner as to permit the separate inflation thereof; the anchor balloon being positioned on the distal end of the shaft and being capable of anchoring the dilator against the bottom of the cervix when inflated after the dilator is inserted in a cervix and the remaining dilation balloons being positioned between the distal and proximal ends so as to effect optimum dilation of the cervical canal when inflated after the device is inserted and anchored in place by inflation of the anchor balloon.
