Abstract

An anvil and delivery system assembly includes an anvil and a delivery system assembly. The delivery system includes a flexible guide member, an adapter, a tie down suture, and a retaining suture. The guide member is coupled to the center rod with the adapter. The tie down suture is secured to the adapter and to the anvil head to retain the anvil head in the tilted position during anvil delivery. The retaining suture is coupled to the anvil head via the tie down suture such that release of the tie down suture automatically releases the retaining suture from the anvil head.
