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.
Claims20
A medical device comprising:
- a device body having an internal reservoir configured to receive a fluid;
- an anchor structure coupled to the device body and having an interior passage;
- a conduit having a fill end and a device end with a conduit lumen extending therethrough, wherein the conduit comprises a weakened section configured to separate the conduit;
- a plug member coupled to the device end of the conduit and comprising a shaft section opposite to a plug section, where the device end of the conduit is concentrically coupled to the shaft section;
- an elastic member in an elastically restrained state;
- and
- a degradable member restraining the elastic member in the elastically restrained state, wherein the degradable member is configured to degrade such that the elastic member moves from the elastically restrained state to an expanded state.

A medical device comprising:
- a device body having an internal reservoir configured to receive a fluid, wherein the internal reservoir is configured to expand in size upon delivery of a fluid into the internal reservoir;
- an anchor structure coupled to the device body and having an interior passage;
- a conduit having a fill end and a device end with a conduit lumen extending therethrough;
- a plug member coupled to the device end of the conduit and comprising a shaft section opposite to a plug section, where the device end of the conduit is concentrically coupled to the shaft section;
- an elastic member in an elastically restrained state;
- and
- a degradable member restraining the elastic member in the elastically restrained state, wherein the degradable member is configured to degrade such that the elastic member moves from the elastically restrained state to an expanded state.

- an anchor structure coupled to the device body and having an interior passage;
- a conduit having a fill end and a device end with a conduit lumen extending therethrough;
- a plug member coupled to the device end of the conduit and comprising a shaft section opposite to a plug section, where the device end of the conduit is concentrically coupled to the shaft section, wherein the shaft section is located completely interior to the internal reservoir;
- an elastic member in an elastically restrained state;
- and
- a degradable member restraining the elastic member in the elastically restrained state, wherein the degradable member is configured to degrade such that the elastic member moves from the elastically restrained state to an expanded state.
