1. A method of stapling layers of tissue within a body cavity, comprising the steps of:
- positioning a stapler having a cartridge, an anvil and a stapling position between the cartridge and anvil, within the body cavity;
passing an engaging instrument through the stapling position and engaging the region of tissue using the engaging instrument;
retracting the engaging instrument to move the engaged tissue into the stapling position; and
driving staples from the cartridge through at least two layers of the engaged tissue.

Abstract
In a method of stapling layers of tissue within a body cavity, an engaging instrument is passed between a stapler cartridge and anvil and used to engage a region of tissue. The engaging instrument is retracted to move the engaged tissue into the stapling position, and driving staples from the cartridge through at least two layers of the engaged tissue. The method and associated system may be used to form plications in body tissue, such as stomach wall tissue. Staples simultaneously driven through tissue may simultaneously capture a reinforcing elements positioned adjacent the cartridge and/or anvil prior to stapling.
