A medical device and procedure is described which can be used for
occluding a fallopian tube. In one implementation, the apparatus includes
an elongate member, an electrode carrier and one or more conductors. The
elongate member has a lumen operable to couple to a vacuum source and
draw moisture way from one or more electrodes included in the electrode
carrier, and a lumen configured to receive a hysteroscope. The electrode
carrier includes one or more bipolar electrodes and can to couple to a
radio frequency energy generator. The one or more conductors connect to a
controller operable to control the delivery of radio frequency energy to
the one or more bipolar electrodes. The elongate member is a
substantially rigid member configured with a curve to facilitate
advancement of the distal end transcervically through a uterus and into a
region of a tubal ostium of a fallopian tube to be occluded.
