Abstract

A method of creating an anastomosis is provided using a stapling assembly including a body extending distally along a longitudinal axis and a deck member defining a deck surface. The deck surface includes a first array of staple openings comprising a herringbone pattern, and each staple opening of the first array of staple openings has a same size. The method includes positioning an anvil within a first lumen of a patient and positioning the stapling assembly within a second lumen of the patient. The method also includes releasably coupling the anvil with the stapling assembly and compressing tissue of the first and second lumens between the anvil and the deck member. The method further includes actuating a plurality of staple drivers to drive a first plurality of staples distally and parallel to the longitudinal axis from the first array of staple openings into the tissue to define the anastomosis.
