Abstract
An apparatus is described for laparoscopically retracting an organ inside the body to provide surgical access to adjacent tissue. The apparatus includes a thin, flexible envelope which encloses a chamber. The envelope is laparoscopically insertable in a collapsed state into a body cavity, and the chamber is inflatable to an expanded state following introduction of the envelope into the body. Inflation of the chamber causes retraction of adjacent tissue. An elastomeric seal is insertable into the chamber following inflation and is attachable to part of the envelope inside the chamber following inflation of the chamber. The seal provides a gas-tight seal to maintain the chamber in the expanded state, and to maintain the organ in the retracted state, notwithstanding the piercing of an aperture in the part of the envelope covered by the seal.
