1. A medical stapling apparatus comprising:
- a first stapling module and a second stapling module, wherein each of the first and second stapling modules comprises;
a first jaw comprising a first end and a second end;
a second jaw comprising a first end and a second end, wherein the first end of the second jaw is pivotally attached to the first end of the first jaw, wherein the second jaw comprises a staple retaining structure adapted to retain one or more staples on the second jaw;
an actuating mechanism capable of selectively rotating the first jaw and the second jaw between an open position and a closed position, wherein the second ends of the first jaw and the second jaw are closer to each other in the closed position than in the open position; and
a guide lumen extending through the first jaw and/or the second jaw of the stapling module.

Abstract
Stapling apparatus and methods of assembling or operating the stapling apparatus are described herein. The stapling apparatus described herein can be delivered through an overtube or other large channel. The stapling apparatus may, in various embodiments, allow for secure closure of, e.g., endoluminal openings such as, e.g., perforations, intentional viscerotomy (e.g., NOTES/full thickness resection), and other indications.

16. A medical stapling apparatus comprising:
-
a base stapling module that comprises; a first jaw comprising a first end and a second end; a second jaw comprising a first end and a second end, wherein the first end of the second jaw is pivotally attached to the first end of the first jaw, wherein the second jaw comprises a staple retaining structure adapted to retain one or more staples on the second jaw; an actuation mechanism capable of selectively rotating the first jaw and the second jaw between an open position and a closed position, wherein the second ends of the first jaw and the second jaw are closer to each other in the closed position than in the open position; a first guide lumen extending through the first jaw of the base stapling module; and a second guide lumen extending through the second jaw of the base stapling module; a delivery device comprising a delivery lumen that extends through the delivery device, wherein the delivery lumen terminates at a distal opening, and wherein the delivery lumen is sized to allow passage of the base stapling module through the delivery lumen; a first guide extending through the delivery device, wherein the first guide passes through the first guide lumen in the first jaw of the base stapling module; a second guide extending through the delivery device, wherein the second guide passes through the second guide lumen in the second jaw of the base stapling module; and one or more supplemental stapling modules, wherein each supplemental stapling module comprises; an anvil element comprising a first end, a second end, and a guide lumen extending through the anvil element, wherein the first guide passes through the guide lumen of the anvil element of the supplemental stapling module; and a staple driver comprising a first end, a second end, and a guide lumen extending through the staple driver, wherein the second guide passes through the guide lumen of the staple driver, and wherein the staple driver comprises a staple retaining structure adapted to retain one or more staples on the staple driver. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A medical stapling apparatus comprising:
-
an elongated body comprising a proximal end and a distal end; a stapling module located at the distal end of the elongated body, wherein the stapling module comprises; a first jaw comprising a proximal end and a distal end; a second jaw comprising a proximal end and a distal end; wherein the proximal end of at least one of the first jaw and the second jaw is pivotally attached to the distal end of the elongated body; staple retaining structure adapted to retain one or more staples on at least one of the first jaw and the second jaw; a tension element comprising a proximal end and a distal end, wherein the distal end of the tension element is fixedly attached to the first jaw proximate the distal end of the first jaw, and wherein the tension element extends through an opening proximate the distal end of the second jaw before extending proximally towards the proximal end of the elongated body; and a tensioning mechanism proximate the proximal end of the elongate body, wherein the proximal end of the tension element is operably attached to the tensioning mechanism, wherein actuation of the tensioning mechanism places the tension element in tension between the distal ends of the first jaw and the second jaw. - View Dependent Claims (32, 33, 34, 35)
