Types of Tubal Ligation (9)
- Bipolar Coagulation
- Fimbriectomy
- Irving Procedure
- Monopolar Coagulation
- Tubal Clip
- Tubal Ring
- Pomeroy Tubal Ligation
- Essure
- Adiana
Types of Tubal Ligation: Bipolar Coagulation
This method uses electrical current to cauterise sections of the fallopian tube
Types of Tubal Ligation: Fimbriectomy
Removing a portion of the fallopian tube closest to the ovary
Types of Tubal Ligation: Irving Procedure
- This procedure calls for placing two ligatures (sutures)
around the fallopian tube - Then removing the segment of tubing between the
ligatures - To complete the procedure, the ends of the fallopian
tubes are connected to the back of the uterus and the
connective tissue respectively
Types of Tubal Ligation: Monopolar Coagulation
Uses electrical current to cauterise the tube together, but also allows radiating current to further damage the tubes as it spreads from the coagulation site
Types of Tubal Ligation: Tubal Clip
The tubal clip or Hulka Clip technique involves the application of a permanent clip onto the fallopian tube
Types of Tubal Ligation: Tubal Ring
The silastic band or tubal ring method involves a doubling over of the fallopian tubes and application of a silastic band to the tube
Types of Tubal Ligation: Pomeroy Tubal Ligation
- A loop of tube is “strangled” with a suture.
- Usually, the loop is cut and the ends cauterised or
“burned“ - This type of tubal ligation is often referred to as cut,
tied, and burned
Types of Tubal Ligation: Essure
- Two small metal and fiber coils are placed in the
fallopian tubes - After insertion, scar tissue forms around the coils
- Blocking off the fallopian tubes and preventing
sperm from reaching the egg
Types of Tubal Ligation: Adiana
- In this method of tubal ligation, two small silicone
pieces that are placed in the fallopian tubes - During the procedure, your health care provider heats
a small portion of each fallopian tube and then inserts
a tiny piece of silicone into each tube - After the procedure, scar tissue forms around the
silicone inserts - Thus blocking off the fallopian tubes and preventing
sperm from reaching the egg
