Tubal ligation requires surgery and is usually performed under general anesthesia. An incision is made in the abdomen and gas is used to expand the abdomen so surgical tools can be inserted. The fallopian tubes are blocked by one of these methods:
Clamping with metal clips or plastic rings
Cutting away a section of the tube
Burning a portion of the tube
The clamps, rings or clips remain in the body. Stitches or staples are used to close the cuts.
