5 b more clearly illustrating the position of the holding rod 60 within the catheter body 51 the pullwire 61 can be manipulated by hand from the proximal end of the catheter to pull the wounding segment proximally within the catheter body the holding rod 60 maintains the plug or plugs in position within the ovarian pathway while the wounding segment is pulled proximally thereby ejecting the plugs from the distal tip of the catheter without moving them relative to the wounded segment of the ovarian pathway after initial positioning and also without moving the catheter body relative to the patient electrical wires which supply rf power to the electrodes may run the through the lumen of the catheter body alongside the pullwire or they may be housed within the catheter body and an electrical connector 63 is supplied on the proximal end of the catheter to connect the wires in the catheter to the rf power supply the electrical wires may also be incorporated into the pullwire with the electrical connections to the rf power supply being disposed on the proximal end of the pullwire other wounding mechanisms may be employed including resistive heating elements direct laser irradiation laser heated elements microwave ultrasound piezo electric abrasion hypothermia cryothermia chemical ablation and mechanical and physical abrasion in use the catheter is inserted into the uterus transcervally and the distal tip of the catheter is navigated into the fallopian tubes until the wounding segment is stationed at the desired point along the ovarian pathway the utero tubal junction is our preferred location for the wound and the plug placement surgeons may view the placement with an endoscope.
