1. A pyloric occlusion device extending longitudinally between a first end and a second end, and configured to shift between a compact delivery configuration and an expanded deployed configuration, said occlusion device comprising:
a first expandable portion having a first end and a second end and a pre-set shape selected to follow a contour of a portion of a stomach surrounding an entrance to a pylorus and to securely seat against the entrance to the pylorus to occlude flow of materials into the pylorus;
a second expandable portion having a first end and a second end and a pre-set shape selected to follow a contour of a portion of a duodenum surrounding a pyloric canal connecting the pylorus and the duodenum to be able to fit within the duodenum; and
an intermediate region between said first expandable portion and said second expandable portion and having a length selected to extend through the pylorus without causing said first expandable portion or said expandable second portion to extend into the pylorus, said intermediate region not defining a lumen therethrough;
wherein:
at least three elongated spaced apart frame elements form said first expandable portion and said second expandable portion, said at least three plurality of frame elements extending longitudinally when said occlusion device is in the compact delivery configuration, and bending outwardly from the first end and from the second end of each of said first expandable portion and said second expandable portion to form a radially-outwardly curved configuration extending from the first end to the second end of each of said first expandable portion and said second expandable portion while extending longitudinally along a direction parallel to a longitudinal axis of said occlusion device when said occlusion device is in the expanded deployed configuration;
at least two of said at least three plurality of frame elements are directly coupled together along the first end of said occlusion device, and along the second end of said occlusion device, along said intermediate region; and
an occlusive material is provided with respect to at least one of said first expandable portion or said second expandable portion to block passage of material through said at least one of said first expandable portion or said second expandable portion.
