Correct Answer » D Explanation |

Method of sterilization shown in the photograph above represents Filshie clip.
The Filshie clip is a hinged device made of titanium lined with silicone rubber. After the fallopian tube has been identified, the Filshie clip is brought to an area of tube 2–3 cm distal to the uterotubal junction. The lower edge of the clip is then visualized through the mesosalpinx to confirm that, when closed, the clip will completely occlude the tubal lumen. The clip is then closed via the applicator, and when closed flattens the curved upper jaw of the clip, occluding the tube. The upper jaw of the clip has a leading edge that extends under the lip of the lower jaw. As necrosis occurs, the rubber expands to keep the lumen blocked. Over time the tube divides into two separate peritoneum-covered stumps.
