Virtual Ports, Ltd. has developed a new laparoscopic liver retractor device, the EndoLift Liver Retractor. This new device does not require additional skin incisions and is placed internally (inside the abdomen) during laparoscopic surgery. The device has 2 ends that "grab" tissue. The body of the device is a smooth, cylindrical steel bar that has minimal risk of traumatizing tissues/organs. The ends of the device are positioned on to peritoneal surfaces (e.g., anterior abdominal wall and/or the right crus of the diaphragm) and the body of the device (smooth cylindrical bar) "pushes" the liver away from the surgical field.
