A system to deliver or remove an inflation expandable stent in a body vessel. The system avoids causing damage or embolisms to a body vessel it is traversing by restraining the edges of the stent from scraping against the walls of the body vessel. The edges are restrained by balloon folds, compressive wedging, and angled reflective resistance. In addition the device can also inflate or deflate the balloon more efficiently.

A flight control system for an airfoil comprises a control surface, a chamber connecting the control surface to the airfoil, and a pneumatic mechanism fluidly connected to the chamber. The chamber may be comprised of at least two cells that may be fluidly separated by a membrane. The pneumatic mechanism is configured to provide differential pressure to the cells in order to alternately increase volume/pressure of the cells to cause deflection of the control surface. The cells may have a stretchable outer surface to allow for changes in the length of the outer surface in response to inflation/deflation of the cells. The outer surface of the cells may be substantially continuous with outer mold lines of the airfoil and of the control surface.

A sheet type balloon has a blank, colorable area partly formed on an outer surface of a body, so the balloon is available for coloring or studying materials as well as typical playing materials. The balloon further has a valve assembly having bi-directional functions, i.e., deflation and inflation of the balloon. To inflate the balloon with air or gas, a fastener of the valve assembly is open by separating a convexly protruding line and a concavely protruding line. After inflation, the fastener is closed by apply a pressure to both protruding lines, so the protruding lines are closely combined and thus intercept the outward flow of inflating air or gas within the body. Then, for carrying or reuse, the fastener can be open again by separating the protruding lines.
