Abstract: A retrieval device comprising a hook assembly and a capsule assembly. The hook assembly has an attachment feature at a first end. The capsule assembly includes a capsule, a capsule shaft, and a handle connected in series and defining an inner bore. The capsule has a first end defining an opening. The inner bore of the capsule assembly is configured to slidably receive the hook assembly. The handle has a central portion, a first extension portion attached to the capsule shaft, and a second extension portion with a hook assembly lock at a second end. The hook assembly lock is configured to lock the hook assembly to the second extension portion. The second extension portion is configured to pull the hook assembly relative to the capsule shaft, and the first extension portion is configured to push the capsule shaft relative to the hook assembly along the central longitudinal axis.

Abstract: A gastrointestinal device for implanting within a patient's gastrointestinal tract, the device having a central axis and a first expandable portion comprising a hollow tubular braided structure of wire and having a first cylinder extending parallel to the central axis, the first cylinder having a length and a first face; a neck portion extending from the first face of the first expandable portion parallel to the central axis, the neck portion having a first end, a second end, a wall extending between the first end and second end, and a diameter sized to fit within a pylorus; and a second expandable portion comprising a hollow tubular braided structure of wire and having a second cylinder extending parallel to the central axis, the second cylinder having a second face located at the proximal end of the second cylinder and oriented transverse to the central axis.
