Abstract
This invention is an expandable intragastric device for reducing food consumption and/or absorption. In an example, this device can be embodied in a plurality of longitudinal expandable members which are arranged in a colonnade configuration to form a restrictive food lumen within a stomach. Pumping a flowable substance between the interiors of these expandable members changes the rate of food flow through the stomach, the capacity of the stomach to hold food, and/or the amount of food absorbed by the body. This offers some of the beneficial effects of gastric sleeve surgery, while also being adjustable and reversible.
Claims20
An implantable expandable intragastric device for reducing food consumption and/or absorption comprising:
- a plurality of expandable members, wherein these expandable members are configured to be inserted into and expanded within a person's stomach, wherein these expandable members are expanded by being filled with one or more flowable substances selected from the group consisting of a gas, a liquid, a gel, and a foam, wherein each expandable member has a proximal surface which is configured to be closer to the gastroesophageal junction, wherein each expandable member has a distal surface which is configured to be closer to the pylorus, and wherein each expandable member has a central axis which spans from its proximal surface to its distal surface;
- and
- a food flow lumen, wherein this food flow lumen has a proximal opening which is configured to be closer to the gastroesophageal junction, wherein this food flow lumen has a distal opening which is configured to be closer to the pylorus, wherein food flows into the proximal opening and out of the distal opening, wherein this food flow lumen has a central axis which spans from its proximal opening to its distal opening, wherein there is at least one plane of this device which is intersected by the central axis of the food flow lumen and the central axes of the expandable members, wherein the points where the central axes of the expandable members intersect this plane can be geometrically connected to form a polygon, and wherein the point where the central axis of the food flow lumen intersects this plane is located inside this polygon.
An implantable expandable intragastric device for reducing food consumption and/or absorption comprising:
- an upper intragastric ring which is configured to be attached to a stomach within the stomach within 6″ of the gastroesophageal junction;
- a lower intragastric ring which is configured to be attached to a stomach within the stomach within 6″ of the pylorus;
- and
- a plurality of longitudinal expandable members, wherein each longitudinal expandable member has an upper end which is attached to the upper intragastric ring and a lower end which is attached to the lower intragastric ring, and wherein each longitudinal expandable member is expanded within the stomach by being filled with one or more flowable substances selected from the group consisting of a gas, a liquid, a gel, and a foam.
An implantable expandable intragastric device for reducing food consumption and/or absorption comprising:
- a flexible mesh or net which is configured to be inserted into a stomach and attached to stomach walls, wherein this flexible mesh or net is attached to stomach walls by two or more intragastric attachment mechanisms, and wherein this flexible mesh or net is configured to span from an upper location within 6″ of the gastroesophageal junction to a lower location within 6″ of the pylorus;
- and
- a longitudinal expandable member which is expanded within the flexible mesh or net within a stomach by being filled with a flowable substance selected from the group consisting of a gas, a liquid, a gel, and a foam.
