Abstract
A cervical access device includes a tubular body having a proximal end, a distal end, and a lumen extending therebetween. A first expansible occlusion member is disposed near the distal end of the tubular body, and a second occlusion member is proximally spaced apart from the first occlusion member. Together, the first and second occlusion members define a reduced diameter neck for receiving the cervical os. In an exemplary aspect, the first occlusion member includes an evertible cylindrical surface which assumes a conical configuration which diverges in the distal direction when actually compressed. The second occlusion member can also be provided with a conical configuration which diverges in the proximal direction so that the first and second occlusion members when brought together define a neck having opposed tapered walls. A catheter for providing thermal treatment to the uterus can be introduced through the cervical access device to perform thermal treatment on the uterus. The cervical access device provides a seal with the cervical os to help prevent heated thermally conductive medium introduced by the catheter from leaking around the cervical access device outwardly into the vagina.
