Swallowable capsule and method for stimulating incretin production within the intestinal tract
First Claim
1. A method for stimulating hormone producing cells (HP-cells) in the intestinal tract of a patient to secrete a glucose regulating hormone (GR-hormone), the method comprising:
- ingesting a swallowable device configured to travel through the intestinal tract and electrically stimulate the HP-cells at any location in the intestinal tract;
delivering an electrical signal from the device to an intestinal wall proximate the device, wherein the signal includes a waveform configured to electrically stimulate HP-cells in the intestinal tract to secrete the GR-hormone without causing a peristaltic contraction.

Abstract
Embodiments of the invention provide apparatus and methods for stimulating L cells in the intestinal tract to produce incretins for the treatment of conditions including diabetes and obesity. Many embodiments provide a method and apparatus for the treatment of diabetes by electrically stimulating L-cells to secrete incretins to stimulate or otherwise modulate the production of insulin. Particular embodiments provide a swallowable capsule for stimulating L-cells in the intestinal tract as the capsule moves through the tract. The capsule can include two or more electrodes for providing electrical stimulation to L-cells, a power source for powering one or more components of the capsule, a sensor for sensing the location of the capsule in the intestinal tract; a controller and a waveform generator for generating the electrical signals emitted by the electrodes to stimulate the L-cells to secrete incretins such as GLP-1 to stimulate insulin production for glucose regulation of diabetic conditions.

1. A method for stimulating hormone producing cells (HP-cells) in the intestinal tract of a patient to secrete a glucose regulating hormone (GR-hormone), the method comprising:
-
ingesting a swallowable device configured to travel through the intestinal tract and electrically stimulate the HP-cells at any location in the intestinal tract; delivering an electrical signal from the device to an intestinal wall proximate the device, wherein the signal includes a waveform configured to electrically stimulate HP-cells in the intestinal tract to secrete the GR-hormone without causing a peristaltic contraction. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A method for stimulating hormone producing cells (HP-cells) in the intestinal tract of a patient to secrete a hormone which modulates a release of insulin, the method comprising:
-
ingesting a swallowable device configured to travel through the intestinal tract and electrically stimulate the HP-cells at any location in the intestinal tract; delivering an electrical signal from the device to a intestinal wall proximate the device, wherein the signal includes a waveform configured to electrically stimulate the HP-cells in the intestinal tract to secrete the hormone without causing a peristaltic contraction of a small intestine; and modulating the release of insulin in the patient responsive to the secreted hormone. - View Dependent Claims (25, 26, 27, 28, 29)

30. A method for stimulating hormone producing cells (HP-cells) in an intestinal tract of a patient to secrete a hormone which suppresses an appetite level of the patient, the method comprising:
-
ingesting a swallowable device configured to travel through the intestinal tract and electrically stimulate the HP-cells at any location in the intestinal tract; delivering an electrical signal from the device to the intestinal wall proximate the device, wherein the signal includes a waveform configured to electrically stimulate the HP-cells in the intestinal tract to secrete the hormone without causing a peristaltic contraction of the small intestine; and suppressing the appetite level of the patient in response to the secreted hormone.
