摘要：
An anvil introduction system is operable to provide smooth insertion of an anvil of a surgical stapling device through a bodily lumen such as the esophagus. The anvil introduction system is coupled to the anvil and includes a dilation feature. The dilation feature has a collapsed position and an expanded position. The dilation feature may cover staple pockets and an outer edge of the anvil with the dilation feature is in the expanded position. The anvil may be inserted through the bodily lumen with the dilation feature in the expanded position. The dilation feature may then be collapsed in order to complete an end-to-end anastomosis of the bodily lumen.
