Intragastric device for treating obesity
First Claim
1. An intragastric device for the treatment of obesity, the intragastric device comprising a digestive-resistant material that is expandable from a first configuration to a second configuration, the first configuration being sufficiently small to permit introduction of said intragastric device into a gastric lumen of a mammal, the second configuration being sufficiently large to prevent said intragastric device from passing through the mammal'"'"'s pylorus, wherein said intragastric device is configured to function as an artificial bezoar.

Abstract
An apparatus and method comprising at least one intragastric member or artificial bezoar made of a digestive-resistant or substantially indigestible material that is introduced into a gastric lumen of a mammal for the treatment of obesity. The intragastric member or artificial bezoar is typically at inserted into the gastric lumen in a partially compacted configuration, whereby it is then manipulated into, or allowed to assume, a second expanded configuration sufficiently large to remain within the reservoir of the stomach during normal activities and not be passed through the pylorus into the intestines. In animals, the present invention has been found to be effective in achieving weight loss over a several month period, while being easy to place and retrieve.

30. A method for the treatment of obesity in mammals, said method comprising the steps of:
-
a) introducing an intragastric device into a gastric lumen of the mammal, said intragastric device comprising a digestive-resistant material that has been compacted into a first configuration that is sufficiently small to permit introduction of said intragastric device into a gastric lumen of the mammal;
b) expanding the intragastric device into a second configuration that is sufficiently large to prevent said intragastric device from passing through the mammal'"'"'s pylorus; and
c) permitting said intragastric device to function as an artificial bezoar.

31. A method for the treatment of obesity in mammals, said method comprising the steps of:
-
a) introducing a plurality of sub-components of an intragastric device into a gastric lumen of the mammal, each sub-component of the intragastric device comprising a digestive-resistant material that is formed into a first configuration that is sufficiently small to permit introduction of said subcomponent into a gastric lumen of the mammal;
b) connecting the plurality of sub-components together to form a unitary intragastric device having a second configuration that is sufficiently large to prevent said intragastric device from passing through the mammal'"'"'s pylorus; and
c) permitting said unitary intragastric device to function as an artificial bezoar.
