1. A method for treating obesity comprising:
- implanting a device within a gastrointestinal tract of an animal, the implanted device having an orifice retained at less than 10 millimeters in diameter, the device implanted entirely in the intestine of the animal; and
with the orifice of the implanted device retained at less than 10 millimeters in diameter, resisting the outflow of chyme from the stomach into the intestines while allowing flow of chyme.

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.

20. A method for treating obesity comprising:
-
implanting a device within a gastrointestinal tract of an animal, the device having a diaphragm, the diaphragm having a hole in a membrane, the hole having an area and being less than 10 millimeters in diameter, there being an open volume before and after the diaphragm, each open volume having a cross-sectional area substantially greater than the hole area; and with the diaphragm, resisting the outflow of chyme from the stomach into the intestines through the hole. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
