An intragastric balloon configured to be implanted transorally into a patient's stomach to treat obesity, the intragastric balloon comprising: an inflatable hollow body, the body having a body volume, wherein, in an implanted state, the body includes: an under-inflated central inflatable member filled partially with a fluid, and a plurality of outer wings in fluid communication with the central inflatable member, the outer wings constructed to transition between a floppy configuration and a stiff configuration when the under-inflated central inflatable member transitions between a relaxed configuration and a squeezed configuration when a compressive force is applied by the stomach to the central inflatable member, wherein the body is made of a material that permits the body to be compressed into a substantially linear transoral delivery configuration, and that will resist degradation over a period of at least six months within the stomach, wherein the central inflatable member and the outer wings define a single internal chamber, such that the fluid can flow freely within the internal chamber, the body being filled with the fluid having a fluid volume that is less than the body volume, the body being constructed to conform to the shape of the stomach.
