Intragastric device for treating obesity
First Claim
1. A non-balloon 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, and further wherein said digestive-resistant material comprises a continuous strip of material that has been folded to form a plurality of loops, said plurality of loops being connected together to form a shape suggestive of a butterfly or bow-tie.

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.
