Abstract
Systems and methods for directionally controlling expansion of an expandable device are described. One such device includes an expandable body comprising a first wall portion and a second wall portion. The first wall portion comprises a high elasticity material. The second wall portion comprises a material having an elasticity lower than the elasticity of the first wall portion. When the body is expanded, expansion of the second wall portion is constrained more than expansion of the first wall portion. Expansion of the body is directed outwardly from the high elasticity first wall portion. Such a device is useful for providing cavities in interior body regions.
