Tubal Ligation with Tubal Rings and Tubal Clips
Tubal rings and tubal clips are mechanical methods of tubal ligation applied to the fallopian tubes through a laparoscope. Tubal rings and clips damage minimal lengths of the fallopian tube and are ideal for tubal reversal.
The tubal ring (also called the Falope ring, Yoon ring, or Lay loop) is a small silastic band placed around a loop of the fallopian tube. With this method of tubal ligation, a 2-3 cm segment of fallopian tube is drawn inside a narrow applicator. The silastic ring is then released onto the tubal loop. As the ring contracts due to its elasticity, it constricts the base of the loop and blocks the fallopian tube. Deprived of its blood supply, the constricted loop is replaced with scar tissue, and the remaining healthy tubal segments separate, similar to the Pomeroy tubal ligation method. The pregnancy rate is 70% following reversal of tubal rings procedures.
The spring clip or Hulka Clip also causes mechanical obstruction of the fallopian tube. This causes the LEAST damage to the tubes of all of the types of tubal ligations. The pregnancy rate is over 80% following reversal with tubal clips.
