ABSTRACT:
This invention relates to a novel design of a device utilized as a dilator regarding various body cavities, and in particular, the human cervix wherein the device comprises a hollow cylindrical member capable of being inserted through the human cervix and into the uterine cavity such that the inflatable membrane positioned about the exterior of that portion of the device inserted into the uterine cavity is capable of being selectively inflated while the device is in the uterine cavity so as to prevent the inadvertent withdrawal of the device. Additionally, once the device is inserted through the cervix and the inflatable membrane about the exterior portion of the device that is positioned within the uterine cavity has in fact been inflated, there is then caused to be inflated a second inflatable membrane positioned about the exterior of the device that is adjacent to the wall of the cervix so as to cause the selective dilation of the cervix in response to the selective inflating of the second inflatable membrane.
