Method for lifting a body wall using an inflatable lifting apparatus
First Claim
1. 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 method comprising the steps of:
- providing a lifting device, the lifting device including a body wall engaging element having a bore and further including a packaged state in which the body wall engaging element forms a package capable of passing through the laparoscopic incision, and a lifting member, the lifting member including a distal portion whereto the body wall engaging element is connected, and a proximal portion and further providing an inflatable retractor;
with the body wall engaging element in the packaged state, advancing the body wall engaging element through the laparoscopic incision;
inflating the body wall engaging element to an inflated state to release the body wall engaging element from the packaged state and to provide a plane lifting surface;
with the body wall engaging element oriented such that the plane lifting surface extends laterally of the distal portion of the lifting member, applying the external lifting force to the proximal portion of the lifting member to move the lifting surface into contact with the body wall;
passing the inflatable retractor in a packaged state through the bore from outside the body wall,inflating the inflatable retractor to an inflated state, andapplying an external retraction force to the inflatable retractor in a direction substantially opposite to the direction of the lifting force, to retract tissue underlying the body wall using the inflated inflatable retractor.

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.
