Abstract:
1. An anvil and anvil delivery system comprising: an anvil assembly including a head assembly and a center rod defining a longitudinal axis, the head assembly defining a transverse axis and being pivotally secured to the center rod and movable from an operative position wherein the transverse axis is substantially perpendicular to the longitudinal axis and a first tilted position wherein the transverse axis defines an acute angle with respect to the longitudinal axis, the head assembly defining a first opening; a flexible tube having an open end secured to the center rod, the flexible tube including gradations along the length of the tube, the gradations being positioned to provide an indication of a length of the tube remaining in a patient during removal from a patient; an adapter having a first end received within the open end of the flexible tube and second end secured to the center rod, the first end of the adapter defining a bore, the adapter being configured to secure the anvil assembly to the flexible tube; a first suture extending through the first opening in the head assembly and the bore of the adapter, the first suture being positioned in tension to maintain the head assembly in the first tilted position, wherein the first suture is positioned in frictional contact between an inner surface of the flexible tube and the first end of the adapter to retain the first suture in tension.
