Abstract
A patient is provided with an increased sense of satiety by increasing resistance to the outflow of food from the stomach and through the intestines. Stomach emptying may be slowed with devices implantable within the gastrointestinal tract below the stomach. Implants are preferably removable and can include artificial strictures that may be adjustable to vary the rate of stomach emptying. Slowing gastric emptying may induce satiety for a longer period and may therefore reduce food consumption. Many of the embodiments include intestinal liners or sleeves, but they need not. The resistor concept may be applied to a simple anchor and resistor without a long liner.

11. A gastrointestinal implant comprising:
-
an anchor adapted for implantation within a gastrointestinal tract of an animal at a position distal to the animal'"'"'s pylorus; and
a resistive element in communication with the anchor, the anchor removably securing the resistive element in position and the resistive element retarding the outflow of food from the stomach. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
