Abstract
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.

19. A device for stapling tissue within a body lumen comprising:
-
a first tube extending from a proximal portion to a distal portion, wherein, in an operative position, the distal portion is located within the body lumen adjacent to a portion of tissue to be stapled, the first tube having a first window extending there through into an interior of the distal portion thereof, at least one edge of the first window forming an anvil;
a stapling mechanism moveably mounted within the distal portion;
a position adjusting mechanism coupled between the first tube and the stapling mechanism for moving the stapling mechanism relative to the first tube to vary a size of a first portion of the window covered by the stapling mechanism. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A method for stapling tissue within a body lumen comprising the steps of:
-
advancing a stapling unit along an endoscope to a location within a body lumen adjacent to a portion of tissue to be stapled, the stapling unit comprising a first casing having a distal end, a proximal end, a first window extending through a periphery of the first casing, and a stapling device;
drawing the portion of tissue to be stapled into the first window;
moving a member of the stapling device relative to the first casing to cover a first portion of the first window and grasp the portion of tissue to be stapled therein; and
operating the stapling device to staple the portion of tissue grasped therein. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56)
