Abstract
Fluid control valves including single-opening, binary fluid control valves that are initially closed and can be opened one time only to allow a fluid transfer between two spaces separated by a fluid impermeable barrier. Applications of valves of this type include inflatable devices, including but not limited to medical device balloons, in particular gastric balloons for weight loss.
Claims1
A fluid control valve for controlling fluid flow, the valve comprising:
- a base defining a fluid path therethrough such that the fluid path is fluidly coupled between a first space and a second space;
- a traveler structure moveable relative to the base between an open configuration and a closed configuration, where in the open configuration the traveler structure permits fluid flow through the fluid path between the first space and the second space, and where in the closed configuration the traveler prevents flow through the fluid path;
- an energy storage device disposed between the between the traveler structure and the base;
- a restraining element that restrains the energy storage device in a stored energy condition where the traveler structure is in the closed configuration, where the restraining element is configured to degrade such that degradation of the restraining element releases the energy storage device from the stored energy condition to cause the traveler to move to the open configuration relative to the base.
