Endoscopic inflatable retraction device
First Claim
1. An inflatable retraction apparatus for retracting an organ inside a body to gain access to an adjacent tissue, the apparatus comprising:
- an inflatable chamber formed from a single thin envelope, the inflatable chamber capable of being collapsed for insertion into the body through an incision of the body and capable of being expanded to a predetermined shape for retracting the organ;
an inflation mechanism adapted to selectively inflate the chamber to the predetermined shape, while the inflatable chamber is in place within the body, the inflation mechanism including at least one inflation tube attached to the inflatable chamber in fluid communication therebetween; and
an inflatable maintaining lattice operatively enveloping the inflatable chamber and in operative association with the inflation mechanism, the inflatable maintaining lattice defining a plurality of single layered access windows around the inflatable chamber, the inflatable maintaining lattice being configured and adapted to maintain the inflatable chamber in substantially the predetermined shape after an aperture is pierced in at least one of the plurality of access windows of he inflatable chamber to provide access to the tissue.

Abstract
An inflatable retraction apparatus is provided for retracing an organ inside a body to gain access to an adjacent tissue. The apparatus includes an able chamber formed from a single thin envelope, and capable of being collapsed for insertion through an incision and being expanded to a predetermined shape for retracing the organ. An inflation mechanism is adapted to selectively inflate the chamber to the predetermined shape. The inflation mechanism includes at least one inflation tube attached to the inflatable chamber in fluid communication theretween, and an inflatable maintaining lattice operatively enveloping the inflatable chamber and in operative association with the inflation mechanism. The inflatable maintaining lattice defines a plurality of single layered access windows around the inflatable chamber, and is configured and adapted to maintain the inflatable chamber in substantially the predetermined shape after an aperture is pierced in at least one of the plurality of access windows of the inflatable chamber.

21. An inflatable retraction apparatus for retracting an organ inside a body to gain access to an adjacent tissue, the apparatus comprising:
-
first and second inflatable chambers each formed from a thin envelope, the first and second inflatable chambers capable of being collapsed for insertion into the body through an incision of the body and capable of being expanded to a predetermined shape for retracting the organ, the second inflatable chamber enveloping the first inflatable chamber and defining a plurality of single layered windows therearound; and
first and second inflating tubes in fluid communication with the first and second inflatable chambers, respectively, for independently inflating the first and second inflation chambers to the predetermined shape, wherein the second inflatable chamber maintains the first inflatable chamber in the predetermined shape following the formation of an aperture in at least one of the plurality of windows to provide access to the tissue. - View Dependent Claims (22, 23, 24, 25)
