An apparatus and method comprising at least one intragastric member comprising a curvilinear axis which extends about and along a central axis of an intragastric device or artificial bezoar made of a digestive-resistant or substantially indigestible material that is introduced into the gastric lumen of a mammal for the treatment of obesity. One or more intragastric members are loaded onto an outer delivery tube in a partially compacted first configuration and delivered to an overtube. The overtube includes a proximal end, a distal end and a main lumen configured to receive the intragastric member in the first configuration for delivery to the gastric lumen wherein the intragastric member is expanded to a second configuration.
