摘要：
Systems and methods for directionally controlling expansion and for radioscopic visualization of the positioning of an expandable device are described. One such device includes an expandable body comprising a first wall portion (53) and a second wall portion (55). The first wall portion comprises a high elasticity material (54). The second wall portion comprises a material having an elasticity lower (56) 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 (Fig 2). Such a device is useful for providing cavities an interior body regions. A radiopaque marking pattern (59) can be configured to allow for visualizing radioscopically the orientation and movement of the expandable body m unexpended and expanded states in an interior body region
