Binary Fluid Control Valve for Rapid Deflation
Here’s PatSnap Eureka !
Summary
Problems
Current self-opening release valves for gastric balloons and similar devices often have uncontrolled degradation rates and flow rates, making rapid deflation challenging, and require invasive endoscopic procedures for removal.
Innovation solutions
A self-opening fluid release mechanism with a binary operation, comprising a valve mechanism, an energy storage device, and a restraining element, where the energy storage device forces the valve to a fully open state once the restraining element loses strength, allowing controlled rapid fluid release.

Specific contradictions:
General conflict description:
Principle concept:
If a self-opening release valve is used for gastric balloons, then invasive endoscopic procedures are reduced, but the fluid release flow rate is uncontrolled and degradation rate is uncontrolled
Why choose this principle:
The patent applies parameter changes by controlling the degradation rate of the release material through material selection and design. The release material is engineered to degrade at a specific rate that enables controlled rapid fluid release. Additionally, the energy storage device parameters (spring constant, pre-compression force) are optimized to achieve the desired binary operation and full aperture opening, transforming the uncontrolled degradation and flow rate into controlled parameters.
Principle concept:
If a self-opening release valve is used for gastric balloons, then invasive endoscopic procedures are reduced, but the fluid release flow rate is uncontrolled and degradation rate is uncontrolled
Why choose this principle:
The patent replaces the traditional mechanical valve control system with a chemically-driven system. Instead of using mechanical actuators or external control mechanisms, the valve operation is driven by the chemical degradation of the release material. This substitution enables the valve to transition from uncontrolled passive release to a more controlled system where degradation kinetics determine the release profile, while the binary mechanical design ensures full aperture opening for rapid flow.

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.
