Abstract
Valve assemblies for use with expandable devices that are positioned within remote cavities and more particularly relates to the catheters/conduits used to inflate these devices with fluid.
Claims28
A valve assembly for use with a balloon device having a fluid port, the valve assembly comprising:
- a jacket member having an outer surface and an interior channel;
- a wall anchor configured to be positioned adjacent to the fluid port, the wall anchor having an interior passage that receives the jacket member to secure a portion of the balloon device therebetween;
- a conduit extending through the interior channel of the jacket member, the conduit having a fill end and a balloon end, with a fill opening located therebetween, wherein the balloon end is occluded such that fluid can pass between the fill end and the fill opening wherein a portion of the conduit and the interior channel are sized to create a sliding resistance therebetween;
- the conduit having an interference region between the fill opening and the balloon end, such that when the conduit moves within the interior channel to position the interference region into the interior channel the interference region becomes secured therein and seals the valve by moving the fill opening through or out of the interior channel;
- and
- a weakened section on the conduit and located towards the interference region, wherein a tensile strength of the weakened section permits a pulling force on the conduit to overcome the sliding resistance and move the conduit within the interior channel but causes failure of the conduit at the weakened section when the pulling force pulls the conduit subsequent to the interference region being secured in the interior channel.

A balloon device comprising:
- a balloon layer defining a reservoir, the reservoir having a fluid port;
- a jacket member having an outer surface and an interior channel;
- a wall anchor positioned within the reservoir and adjacent to the fluid port, the wall anchor having an interior passage that receives the jacket member to secure a portion of the balloon layer therebetween;
- a conduit extending through the interior channel of the jacket member, the conduit having a fill end and a balloon end, with a fill opening located therebetween, wherein the balloon end is occluded such that fluid can pass between the fill end and the fill opening wherein a portion of the conduit and the interior channel are sized to create a sliding resistance therebetween;
- the conduit having an interference region between the fill opening and the balloon end and located within the reservoir, such that when the conduit moves within the interior channel to position the interference region into the interior channel the interference region becomes secured therein and seals the valve by moving the fill opening through or out of the interior channel;
- and
- a weakened section on the conduit and located towards the interference region, wherein a tensile strength of the weakened section permits a pulling force on the conduit to overcome the sliding resistance and move the conduit within the interior channel but causes failure of the conduit at the weakened section when the pulling force pulls the conduit subsequent to the interference region being secured in the interior channel.
