Stimulating Bladder Or Gastrointestinal Tract Patents (Class 607/40)
  • Patent number: 9643005
    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.

  • Patent number: 9616225
    Abstract: The present specification discloses devices and methodologies for the treatment of GERD. Individuals with GERD may be treated by implanting a stimulation device within the patient's lower esophageal sphincter and applying electrical stimulation to the patient's lower esophageal sphincter, in accordance with certain predefined protocols. The presently disclosed devices have a simplified design because they do not require sensing systems capable of sensing when a person is engaged in a wet swallow, have improved energy storage requirements, enable improved LES function while concurrently delivering additional health benefits, and enable improved LES function post stimulation termination.

  • Publication number: 20150119952
    Abstract: Systems and methods for the treatment of gastroesophageal reflux disease (GERD) include at least one electrically stimulating electrode coupled to a pulse generator. Individuals with GERD are treated by implanting a stimulation device within and/or proximate the patient's lower esophageal sphincter, gastric fundus, or other nearby gastrointestinal structures and applying electrical stimulation to the patient's lower esophageal sphincter and/or fundus, in accordance with certain predefined protocols. Electrical stimulation provided by the disclosed systems results in an increase in the length of the high pressure zone of the LES and/or modulation of the receptive relaxation response of the fundus to decrease gastric pressure, creating a longer barrier to the reflux of gastric contents or increasing functional lower esophageal pressure respectively, thereby treating GERD.

  • Patent number: 9020597
    Abstract: The present specification discloses devices and methodologies for the treatment of GERD. Individuals with GERD may be treated by implanting a stimulation device within the patient's lower esophageal sphincter and applying electrical stimulation to the patient's lower esophageal sphincter, in accordance with certain predefined protocols. The presently disclosed devices have a simplified design because they do not require sensing systems capable of sensing when a person is engaged in a wet swallow, have improved energy storage requirements, enable improved LES function while concurrently delivering additional health benefits, and enable improved LES function post stimulation termination.

  • Patent number: 8992409
    Abstract: There is provided a method for controlling a flow of fluid and/or other bodily matter in a lumen formed by a tissue wall of a patient's organ. The method comprises gently constricting (i.e., without substantially hampering the blood circulation in the tissue wall) at least one portion of the tissue wall to influence the flow in the lumen, and stimulating the constricted wall portion to cause contraction of the wall portion to further influence the flow in the lumen. The method can be used for restricting or stopping the flow in the lumen, or for actively moving the fluid in the lumen, with a low risk of injuring the organ. Such an organ may be the esophagus, stomach, intestines, urine bladder, urethra, ureter, renal pelvis, aorta, corpus cavernosum, exit veins of erectile tissue, uterine tube, vas deferens or bile duct, or a blood vessel.

  • Patent number: 8972014
    Abstract: An enuresis electroconditioner pertains to the field of medical appliances and includes a humidity sensor (2) connected to an electric circuit which is activated in the presence of a liquid. When the liquid is detected, an electric current with a frequency of 50 Hz is generated. A qualified person must calibrate the amperage of the apparatus (1), adapting it to the sensibility of each person who, when receiving the electric impulse, contracts the perineal muscles, occluding the urethra and by a reflexive action inhibiting the contraction of the bladder and preventing urine loss.
