1. A system for protecting an anastomosis in an intestine, the system comprising:
an anchor configured to be implanted at a target location in the intestine upstream of the anastomosis, the anchor configured to transition from a compressed state to an expanded state wherein an outer surface of the anchor contacts an inner wall of the intestine at the target location;
a sheath disposed within the anchor and coupled to the anchor to define a negative pressure chamber between an outer surface of the sheath and the inner wall of the intestine;
one or more fluid inlet tubes fluidically coupling the negative pressure chamber to a pump,
wherein the outer surface of the sheath comprises a micropattern of microstructures, each microstructure comprising a protrusion configured to inhibit the inner wall of the intestine from sealing against the outer surface of the sheath to maintain a vacuum throughout the negative pressure chamber such that the anchor remains anchored at the target location when negative pressure is applied in the negative pressure chamber by the pump via the one or more fluid inlet tubes.
