Devices and methods for weight control and weight loss

摘要

The present invention provides, compositions, devices; and methods for affecting, among other things, weight loss and/or weight control, by sequestering nutrients or other compounds such as toxins from absorption in the digestive tract. The compositions, devices, and methods employ one or more members made of a compressible, absorbent matrix material. In various embodiments, the matrix material is suitable for routine use. The compressible absorbent matrix material has a size, shape and/or geometry configured for efficient packing into a small space, and/or configured to absorb and substantially retain digested material in the stomach. The devices and compositions may further comprise one or more hydrogel(s), soluble or insoluble fibers, waxes and/or gums to provide the desired mechanical properties and/or absorptive or shielding properties.

主权项

1. A device for preventing absorption of nutrients or other compounds in the stomach, the device comprising:
one or more member of a compressible absorbent matrix material having a configuration that is packed into a compressed delivery vehicle that is less than 50% of an expanded size of the delivery vehicle, wherein the absorbent matrix material forms a sponge architecture, including a plurality of cells defined by cell walls, wherein the absorbent matrix material, once released in the stomach, absorbs nearby nutrients or compounds thereby preventing the stomach from absorbing the same nutrients or compounds, and wherein one or more sealing compounds are contained in the cell walls; and a delivery vehicle that encapsulates the compressible absorbent matrix material, wherein the delivery vehicle is ingested by a user, and wherein the ingestion triggers a release of the compressible absorbent matrix into the stomach of a user.
