Multi-fire stapling systems and methods for delivering arrays of staples

摘要

A staple housing includes an array of staples each in a staple delivery position or “ready position” ready to be fired into target tissue. A staple driver is advanceable to drive the ready-position staples from the staple head into the tissue using staple pushers. During use, the staples in the ready positions are simultaneously fired into the target tissue using the staple pushers, forming an array of staples in the target tissue. After the array has been fired, one or more feed mechanisms within the staple housing advance a second group of staples from one or more staple storage locations into the ready positions in preparation for firing of the second group of staples.

主权项

1. A method of producing at least one tissue plication within a body cavity, comprising the steps of:
(a) intraorally introducing a stapler into the body cavity, the stapler having a staple housing including a plurality of staple-holding cells, wherein each of the plurality of staple-holding cells contains multiple staples; (b) positioning the staple housing at a first position in the body cavity; (c) acquiring a tissue fold at the first position; and (d) driving a plurality of staples from the staple-holding cells into the tissue fold, to form a tissue plication fastened with the plurality of staples, wherein staples arranged longitudinally from a proximal end of the staple housing to a distal end of the staple housing are ejected simultaneously from the staple housing.
