How does rubber band ligation work?

Tubal ligation. This is a surgical procedure performed under anesthesia by laparoscopic surgery using band-aid size incisions. Abdomen is inflated with carbon dioxide...You are asleep. The surgeon can see inside your abdomen with a highly specialized 'telescope'. A small silastic band is placed around a 'knuckle' of each tube, the ends seal off and separate, thereby creating a blockage which prevents conception.
