A thermal ablation device includes an elongated member sized and shaped for insertion into a uterus via a cervical opening. The elongated member defines a first lumen extending therethrough to a first distal opening which, when the apparatus is in an operative position, opens into the uterus and a seal positioned on the elongated member so that, when the elongated member is in the operative position, the seal engages cervical tissue around a circumference of the elongated member and prevent fluids introduced into the uterus via the first lumen from flowing therepast into the cervix. The seal includes a plurality of flexible members separated from one another along a length of the elongated member and projecting radially outward from an outer surface of the elongated member. |
