    Abstract: An apparatus includes a body, a shaft assembly, an end effector, and a staple cartridge. The end effector includes an anvil and a lower jaw. The anvil is pivotable toward the lower jaw to capture tissue between the anvil and the lower jaw. The staple cartridge is coupled with the lower jaw. The staple cartridge includes a deck and a plurality of staples. The deck faces the anvil. The anvil or the deck (or both) includes a compressible that extends toward the other of the anvil or the deck. The compressible feature of the anvil of the deck is configured to compress tissue against the other of the anvil or the deck.

    IPC: A61F5/00

    Abstract: An apparatus comprises a sleeve, a seal, and an anchor assembly. The sleeve is flexible and non-permeable and is configured to fit in a duodenum. The seal is positioned at the proximal end of the sleeve and is configured to seal the proximal end of the sleeve against the stomach mucosa, the pylorus, or the duodenum mucosa. The anchor assembly comprises a pair of atraumatic anchor ends and a resilient member positioned between the anchor ends. At least a portion of the resilient member extends along at least a portion of the length of the sleeve. The resilient member is configured to bias the anchor ends generally toward each other, to thereby substantially anchor the sleeve in the duodenum. The sleeve is configured to prevent chyme from contacting the mucosa of the duodenum; and to prevent enzymes excreted in the duodenum from mixing with chyme in the duodenum.
