A stapling unit for use with an endoscopic stapling system adapted to be advanced along an endoscope to a predetermined location within a body lumen to staple the portion of tissue, as part of an occlusal or full thickness resectioning procedure. The stapling unit comprises a first casing having a distal end, a proximal end and a stapling device mounted thereto adjacent to a first window extending through a periphery of the first casing. The invention includes methods for the stapling, severing and removal of tissue by using the device.
An operating head for a full thickness resection system includes a first optical device disposed on a distal portion thereof and having a viewing area extending distally of the distal portion and a working chamber extending within an exterior wall of the operating head, a first portion of the exterior wall being moveable with respect to a second portion thereof to selectively open the working chamber to an exterior of the operating head. Furthermore, the operating head includes a second optical device mounted within the working chamber with a viewing area of the second optical device extending distally therefrom.
The present invention is directed to a full-thickness resection system comprising a flexible endoscope and a stapling mechanism, wherein the endoscope is slidably received through at least a portion of the stapling mechanism. The stapling mechanism includes an anvil and a stapling head mounted to the anvil so that the anvil and the stapling head are moveable with respect to one another. A position adjusting mechanism is provided for moving the anvil and the stapling head relative to one another. An integrated surgical retainer for use in the full thickness resectioning device is described. The integrated surgical staple retainer comprises a calibrating portion, a retaining portion, and a grasping portion. The calibrating portion defines a circular opening which has a diameter substantially equal to a diameter of a working channel of the full thickness resectioning device. The retaining portion has a lower surface adapted to limit movement of the surgical staples in the full thickness resectioning device and is adjacent to the calibrating portion of the integrated surgical staple retainer.
