  • Patent number: 10596021
    Abstract: Various devices, systems, and methods that can be used in the treatment of obesity and related illnesses are disclosed. In some instances, a portion of the bowel of an obese patient is distended for a therapeutically effective period. The distention may be achieved by introduction of an object that is of foreign origin relative to the body of the patient into the bowel of the patient. In some instances, the distention is achieved by a medical device that transitions from an undeployed state, in which the medical device is introduced into the bowel of the patient, to an expanded state in which the medical device distends the bowel by an amount sufficient to trigger an intestinal-gastric brake in the patient.

  • Patent number: 10588698
    Abstract: A method of surgically positioning an electrode array at a desired implantation location relative to a nerve. A temporary probe electrode is temporarily positioned adjacent to the nerve and at a location which is caudorostrally separate to the desired implantation location of the electrode array. The implanted position of the probe electrode is temporarily fixed relative to the nerve. During implantation of the electrode array, electrical stimuli are applied from one of the temporarily fixed probe electrode and the electrode array, to evoke compound action potentials on the nerve. Compound action potentials evoked by the stimuli are sensed from at least one electrode of the other of the temporarily fixed probe electrode and the electrode array. From the sensed compound action potentials a position of the electrode array relative to the nerve is determined.
