Abstract
A medical device and procedure is described for occluding a fallopian tube. A tubal occlusion device is inserted into a uterine cavity. The device includes an RF applicator head including an electrode carrier with one or more bipolar electrodes thereon. During insertion, the RF applicator head can be in a closed position. The RF applicator head is positioned at a tubal ostium of a fallopian tube, such that a distal tip of the RF applicator head advances into the tubal ostium. The RF applicator head is deployed into an open position such that the RF applicator head approximates the shape of the uterine cavity in a region of the tubal ostium. Current is passed through the one or more bipolar electrodes to the tubal ostium to destroy tissue to a known depth, which precipitates a healing response in surrounding tissue that over time scars and occludes the fallopian tube.
