1. A reactive implantable device configured to be placed in a patient'"'"'s stomach transorally without surgery to treat and prevent obesity by applying a pressure to the patient'"'"'s stomach, comprising:

  • a three-dimensional spring structure comprising a plurality of legs each having opposite ends extended between top and bottom junctions of the spring structure defining an axis, each leg having a flexible portion and a rigid portion attached to the flexible portion, wherein the flexible portions of each leg has a relaxed shape which causes the leg to bow laterally outward from the other legs thus maintaining the top and bottom junctions at a first distance apart, and wherein the implantable device is configured to react to inward forces from the stomach such that the flexible portions flex to straighten each leg and cause the axial spacing between the top and bottom junctions to increase from the first distance,wherein the device is formed of materials that permit it 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.
