ABSTRACT:
An apparatus deployed through a laparoscopic incision in a body wall to apply an external lifting force over a large area of the body wall. The apparatus comprises a body wall engaging element and an elongate lifting member. The body wall engaging element is capable of passing in a packaged state through the laparoscopic incision, is inflatable to an inflated state, and includes, in the inflated state, a plane lifting surface. The elongate lifting member includes a distal portion connected to the plane lifting surface, and capable of passing through the laparoscopic incision. A proximal portion receives the external lifting force in a direction that moves the body wall engaging element into contact with the body wall. A method for lifting a body wall by applying an external lifting force to a large area of the body wall through a laparoscopic incision. The lifting device is provided that includes an body wall engaging element capable of passing through the laparoscopic incision in a packaged state. The lifting device also includes a lifting member including a distal portion to which the body wall engaging element is connected. The body wall engaging element and the distal portion of the lifting member are advanced through the laparoscopic incision. The body wall engaging element is inflated to an inflated state to provide a plane lifting surface. Finally, the external lifting force is applied to the proximal portion of the lifting member to move the lifting surface into contact with the body wall.
