ANTI-OBESITY DEVICES

摘要

A restrictive device (216) implanted in the upper part of the stomach, selectively divides the stomach into two chambers (220, 222), effectively reducing the size of the stomach immediately available for the uptake of food. The restrictive device also includes an aperture (218), limiting the rate at which food can pass from the esophagus portion of the stomach into the intestine. Being removable, the device permits a physician to change the size of the opening in a minimally invasive manner by replacing a removable member with another member having an aperture of a different size and/or shape. The restrictive device can also be combined with an elongated tube (302), or sleeve to selectively bypass the stomach, a portion of the intestine, or a combination of bypassing both the stomach and a portion of the intestine, allowing a physician to endoscopically create an equivalent to the Roux-en-y weight loss procedure.
