The Pulley maneuver using barbed sutures has been used for laparoscopic hepatectomy; however, the sutures are single-use and may pass through the liver parenchyma, making it uneconomical and inflexible.

The sutures were anchored to the diaphragm or peritoneum for optimal liver traction. A laparoscopic or robotic grasper adjusted the suture tension for the appropriate transection plane.
