Claim Text:
1. An intragastric device comprising: a wire mesh structure comprising a top, a bottom, and an interior and having a pre-deployment shape with a first volume and a post-deployment shape with a second volume greater than said first volume, wherein, in said post-deployment shape, said wire mesh structure includes at least one first opening proximate said top and at least one second opening proximate said bottom such that at least some food enters said wire mesh structure through said at least one first opening, passes through said interior, and exits said wire mesh structure through said at least one second opening and wherein, when in said post-deployment configuration, wires of said wire mesh structure comprise 50% or less of a total surface area of said wire mesh structure and openings between said wires comprise a remaining surface area; an anti-migration component positioned at the bottom of said wire mesh structure and attached to said wire mesh structure, wherein said anti-migration component comprises a compressed pre-deployment configuration and an expanded post-deployment configuration and is designed to sit proximal to a patient's pylorus and prevent migration of the wire mesh structure into or through said pylorus; and a sleeve having a flexible elongate body, a proximal end with a third opening, a distal end with a fourth opening, and a sleeve interior, wherein said sleeve is coupled to said anti-migration component such that food exiting said at least one second opening enters said sleeve through said third opening, passes through said sleeve interior, and exits said sleeve through said fourth opening.
