1. A device that is configured to wrap around a stomach of a patient and preventing overexpansion thereof in a radial direction as well as limiting axial lengthening thereof in an axial direction, the device comprising;
a body comprising an inner surface and an outer surface, and a compressible pliant material being located between the inner surface and the outer surface of the body;
the inner surface of the body defining a passage that is adapted to accommodate the stomach of the patient, and the passage extending through the device from an inlet to an outlet of the device and having opposed first and second end surfaces;
the stomach, following surgical implantation of the device, is configured to be accommodated within the passage of the device and is configured to be completely circumferentially wrapped and surrounded by the device both in the radial direction as well as in the axial direction, between the opposed first and second end surfaces, such that an esophagus of the patient is configured to pass through the inlet of the device while a small intestine of the patient is configured to pass through the outlet of the device;
the inner surface of the device, in an uncompressed/slightly compressed state of the device, defining a normal state due which is configured to provide circumferential support to an outer wall of the stomach and prevent overexpansion thereof in both the radial and axial directions while continuously permitting flow of bodily material into and through the stomach;
as the stomach attempts to expand radially from the normal state due to the bodily material flowing into and through the bodily organ stomach, the stomach is configured to abut against the inner surface of the device and the stomach is configured to radially bias the inner surface of the device radially outwardly into the compressible pliant material thereby compressing the compressible pliant material toward the outer surface of the device, and such compression of the inner surface and the compressible pliant material, as the outer wall of the stomach attempts to expand, correspondingly exerting a resisting force, against the outer wall of the stomach, which limits and opposes the expansion of the stomach and forces the outer wall of the stomach back toward and into its normal state of the outer wall of the stomach which permits the flow of the bodily material into and through the stomach; and
as the stomach attempts to expand axially from the normal state due to the bodily material flowing into and through the stomach, the stomach is configured to abut against an inner surface of opposed first and second end walls of the device and the stomach is configured to axially bias the inner surfaces of the opposed first and second end walls of the device axially outwardly into the compressible pliant material thereby compressing the compressible pliant material toward the outer surface of the device, and such compression of the inner surface and the compressible pliant material, as the outer wall of the stomach attempts to expand axially, correspondingly exerting a resisting force against the outer wall of the stomach, which limits and opposes the expansion of the stomach in the axial direction and forces the outer wall of the stomach back toward and into its normal state of the outer wall of the stomach which permits the flow of the bodily material into and through the stomach.
