Luminal anastomotic device
First Claim
1. A surgical anastomotic fastener array comprising a plurality of fasteners each having at least one tissue piercing element, wherein the fasteners are aligned in an annular array of a first diameter prior to anastomosis and are configured to move in a radial direction to form an annular array of a second diameter different from the first diameter, and a mechanism for accommodating radial movement of the annular array of fasteners.

Abstract
An end to end anastomotic stapling device connects two lumen sections avoiding constriction at the anastomotic ring. An intraluminal end to end anastomotic stapler includes an expanding head and anvil designed to fire an anastomotic ring having an inner diameter at least equal to the nominal inner diameter of the remaining lumen sections. An extraluminal end to end lumen stapler is described attaching the lumen sections with an exterior flange type connection having anastomotic rings with a diameter larger than the inner diameter of the lumen sections whereby the anastomotic site has a diameter at least as great as the adjacent lumen sections.
