1. An anvil delivery system comprising:
- a delivery assembly;
an anvil assembly selectively securable to the delivery assembly, the anvil assembly including;
a center rod assembly selectively securable to the delivery assembly; and
a head assembly pivotally secured to the center rod assembly between a first tilted position and an operative position; and
a suture extending from the anvil delivery system through the head assembly and distally of the head assembly when the head assembly is in the first tilted position, wherein the suture retains the head assembly in the first tilted position.

Abstract
An anvil assembly suitable for trans-oral delivery includes an anvil head configured to receive a suture that secures the anvil head in a delivery position and is separable from the anvil head following delivery of the anvil assembly. An anvil delivery assembly includes the anvil assembly, a delivery assembly secured to the anvil assembly, and a suture selectively secured to the anvil assembly for securing the anvil assembly in a delivery position and retrieving the anvil assembly.
