Abstract
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.
