Anti-obesity devices
First Claim
1. A gastrointestinal implant device comprising:
- a restrictive member configured for implantation into a stomach of an animal, the restrictive member configured to divide the inner volume of the stomach into a proximal chamber and a distal chamber; and
an anchor fixedly coupled to the stomach and removably coupled to the restrictive screen for securing the restrictive screen within the stomach.

Abstract
A restrictive device implanted in the upper part of the stomach, selectively divides the stomach into two chambers, effectively reducing the size of the stomach immediately available for the uptake of food. The restrictive device also includes an aperture, 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, 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.

21. A method of treating obesity comprising the steps of:
-
providing a restrictive member;
providing an anchor;
fixedly coupling the anchor to an upper portion of an animal'"'"'s stomach;
removably coupling the restrictive member to the anchor, the restrictive member, when coupled, dividing the inner volume of the stomach into a proximal chamber and a distal chamber and limiting the rate that food can pass therethrough.

23. A gastrointestinal implant device comprising:
-
a restrictive device defining a restrictive aperture, the device configured for implantation into an upper part of a stomach of an animal;
a variable length elongated tube, open at both ends, and coupled at its proximal end to the restrictive device, the tube adapted to extend at least about to the pylorus to limit absorption of nutrients in the stomach, and an anchor coupled to the elongated tube for securing at least a distal portion of the elongated tube. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)

43. A method of treating obesity comprising the steps of:
-
endoscopically placing a removable, variable restrictive device in an upper part of a stomach;
endoscopically placing a removable, variable length sleeve in the duodenum and jejunum; and
connecting the sleeve to the restrictive device. - View Dependent Claims (44)

45. A method of causing weight loss comprising the steps of:
