The endosquid, a new device for laparoscopic Pomeroy tubal ligation

The Pomeroy method is a most widely practiced and most familiar form of tubal ligation. It traditionally requires laparotomy or multiple-puncture laparoscopic suturing, which is not a realistic option for the average endoscopist. We designed a 5-mm device, the Endosquid, to reproduce Pomeroy tubal ligation laparoscopically using a single 5-mm accessory puncture site. It is able to ligate, transect, and remove a loop of isthmic tube. We tested the Endosquid in a porcine model by ligating 25 bicornuate uterine horns and aortas. Ligation times averaged less than 5 minutes for each application. Gross and histologic evaluation of ligation specimens performed at necropsy confirmed correct placement. Blood loss was negligible and there were no operative complications.
