  • Patent number: 8702642
    Abstract: Components may be used separately or in combination to create anchoring systems for intra-luminal implants for the treatment of metabolic disorders such as obesity and diabetes. Various systems include an external component adapted for deployment around a portion of the gastrointestinal tract (e.g., the duodenum) and an internal component adapted for implantation within the gastrointestinal tract. Various systems use anchors that are based on mechanical interference, elasticity, spring force, shape memory transformation, magnetic attraction, repulsion and/or levitation. Various embodiments rely on longitudinal anchoring of the implants with minimal force against tissue.

  • Patent number: 8597224
    Abstract: An intragastric anchor implant device is provided with a substantially rigid member having proximal and distal ends and atraumatic tips or features disposed near the proximal and distal ends. The atraumatic features prevent damage to the tissues of the stomach and the gastrointestinal track and may help to anchor the device in the stomach, while the substantially rigid member resists bending so as to engage a tissue of the stomach or the gastrointestinal tract to prevent passage through the stomach. The anchor implant device is coupled with a therapeutic device, typically a sleeve, such as an intestinal bypass sleeve. Ideally, the device includes a sliding seal to direct a flow of food particles from the stomach through the sleeve, so as to be useful in treating a disorder, including obesity and diabetes. Methods of deploying the anchor implant devices are also disclosed.

  • Patent number: 8425401
    Abstract: An inflatable gastric band incorporates a fluid channel within an outer surface of the band and an inflatable bladder on a stomach-facing side of the band. The gastric band attaches to a double lumen catheter, which communicates with a dual infusion port. One lumen communicates with the fluid channel and one port, while the other lumen communicates with the inflatable bladder and a second port. Injection of fluid into one chamber of the infusion port expands inflatable bladder, allowing adjustment to the diameter of the stoma. Injection of drugs or therapeutic agents into the second chamber allows the infusion of drugs or agents directly into the abdominal cavity of a gastric band recipient. The inflatable bladder can be continuous or segmented. A segmented bladder reduces pinching and/or folding of the inner surface of the gastric band during expansion/contraction, thereby lessening stomach pinching and/or irritation.

  • Patent number: 7326207
    Abstract: This invention provides a method and system for the curative treatment of obesity. A first aspect of this invention is that it enables identification of the nerves responsible for the relaxation of the stomach muscles that occurs prior to and during eating. A second aspect of the invention is that it allows the physician to identify focal nerve sites in the stomach and upper duodenum that are associated with producing sensations of hunger and satiety. Nervous transmission from these sites can be modulated or blocked all together so as to minimize the sensation of hunger. A third aspect of this invention is that allows a physician to shrink selected portions of the innermost oblique muscle and middle circular muscle layers of the stomach. This can be performed in a physician's office using local anesthesia. Shrinkage of these muscles produces a feeling of satiety that enhances the patient's efforts to restrict his caloric intake.
