Abstract
Embodiments disclosed herein relate to methods, devices, and computer systems thereof for reducing stomach volume in a subject. In certain embodiments, a subject receives a stomach-volume-reducing device that optionally includes at least one reservoir configured to release at least one appetite suppressant. In an embodiment, the stomach-volume-reducing device is responsive to one or more environmental conditions of the subject, for example, pH or chemical chemicals in the stomach of the subject. In an embodiment, the stomach-volume-reducing device controls hunger in the subject.
Claims40
A device, comprising:
- a reversibly responsive expandable housing configured to reversibly expand or contract and encasing at least one intelligent responsive matrix that is responsive to at least one environmental condition in the stomach of a subject;
- at least one entry port;
- and
- at least one controllable micropump or controllable valve operably connected to the at least one port, and operably coupled to control circuitry.
A system, comprising:
- circuitry configured to operate at least one stomach-volume-reducing device;
- the stomach-volume-reducing device including a reversibly responsive expandable housing configured to reversibly expand or contract and encasing at least one intelligent responsive matrix that is responsive to at least one environmental condition in the stomach of a subject;
- at least one port;
- and at least one controllable micropump or controllable valve operably connected to the at least one port and
- at least one sensor and one or more detection processors configured to determine changes in the concentration of pH or change in nerve signaling from the subject relative to time.
