SYSTEM FOR GASTRIC RESTRICTION AND MALABSORPTION

摘要

The present disclosure relates generally to prosthetic devices for use in restricting food and caloric intake into the stomach and of absorption of the food components in the stomach and small intestine. The system includes an elongated bariatric sleeve having a normally superior or upper proximal end and a normally inferior or lower distal end. An elongated lumen support member is positioned within the first lumen in contacting relation with the first membrane for maintaining the first lumen in an open position. A proximal anchor ring with a central aperture and a catheter channel is connected to the proximal end of the sleeve to the collar member. The anchor is inflatable or expandable memory material for anchoring the sleeve in superior relation to a pyloric valve of the patient's stomach. An anchor weight is connected to the distal end of the first flexible tube. The device further includes a tether or a delivery catheter connected to a gastric port to aide in minimizing movement of the device and the device for delivery of nutritional and pharmaceutical compositions through the gastric opening and into the second lumen where they may be absorbed by the proximal duodenum and jejunum of the small intestine. The system can also include an intragastric displacement balloon.
