An intragastric device configured for catheter deployment in a stomach comprises first and second wire mesh structures having a pre-deployment shape that is compressed within the lumen of the catheter, a post-deployment shape that is expanded within the stomach of the person, openings on an upper portion of the first mesh, and openings on a lower portion of the second mesh. The device also includes a connection to flexibly couple a lower portion of the first structure to an upper portion of the second structure such that the two structures are in fluid communication. Food enters the upper portion of the first wire mesh structure, passes through both wire mesh structures, and then exits the lower portion of the second wire mesh structure. Optionally, a sleeve is coupled to the lower portion of the second wire mesh structure and extends into a duodenum of a person.
