Abstract
The present application provides intragastric devices for the treatment of obesity. The intragastric devices advantageously act as a volume-occupying device, and is able to survive implantation in a patient'"'"'s stomach for a year or longer. In addition, the intragastric devices may provide additional benefits. For example, the intragastric device may be configured to stimulate an inner stomach wall and/or temporarily block the pylorus to slow gastric emptying and/or be rotationally variant, thereby encouraging different stimulation points on the inner wall of the stomach and limiting the stomach'"'"'s ability to adapt over long term implantation.

21. An intragastric device for occupying space in a patient'"'"'s stomach and for treating obesity, the intragastric device comprising:
a plurality of round protrusions attached to one another and projecting outward from a center of the intragastric device, the protrusions configured to permit rotation of the intragastric device as stomach muscles contracts, wherein each protrusion can substantially block the entrance of the pylorus to the stomach, without residing within the pylorus, thereby impeding flow of food into the stomach, the device capable of remaining in the stomach and functioning therein for at least one year to treat obesity. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)

29. An intragastric device for occupying space in a patient'"'"'s stomach and for treating obesity, the intragastric device comprising:
a plurality of legs attached to one another and projecting outward from a center of the intragastric device, the plurality of legs configured such that the intragastric device is rotationally variant depending on natural contractions of the patient'"'"'s stomach, wherein each leg terminates in a leg end larger than the rest of the leg and sized to temporarily block the pylorus of the patient when the leg end contacts the pylorus but being too large to fit within the pyloris opening, the device further configured to be functional inside the patient'"'"'s stomach for a year or more. - View Dependent Claims (30, 31, 32, 33, 34)

35. An intragastric device for occupying space in a patient'"'"'s stomach, the intragastric device comprising:
a hollow body having an interior chamber and an exterior surface defined by a wall of the hollow body, wherein the exterior surface is not smooth but has a plurality of mini surface stimulation features thereon, the body further configured to be functional inside the patient'"'"'s stomach for a year or more. - View Dependent Claims (36, 37, 38, 39, 40, 41, 42)
