## 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.

## Claims

### Claim 1

A valve assembly for use with a balloon device having a fluid port, the valve assembly comprising:
a jacket member having an elongated shape, an outer surface and an interior channel, the interior channel comprising an engagement member;
a wall anchor positioned within the balloon device and adjacent to the fluid port, the wall anchor having an interior passage that receives the jacket member, where a portion of the balloon device adjacent to the fluid port extends into the interior passage of the wall anchor and is secured between the outer surface of the jacket member and the interior channel of the wall anchor;
a conduit extending through the interior channel of the jacket member, the conduit having a fill end and a balloon end, the balloon end comprising an interior section, wherein the conduit and the interior channel are configured to have a sliding resistance therebetween, the interior section comprising a weakened section and a fill opening, a portion of the interior section being occluded to prevent fluid from flowing therethrough;
the interior section having an interference region that is configured to become fixedly engaged within the interior channel when moved therein to assume a locking profile;
wherein the weakened section is located between the fill end of the conduit and the interference region, wherein the weakened section has a reduced tensile strength less than a tensile strength of the conduit while permitting sliding of the conduit relative to the interior channel upon an application of a pulling force on the conduit without causing separation at the weakened section, wherein the reduced tensile strength requires a tearing force to cause separation of the conduit at the weakened section; and
wherein the fill opening is located at the interior section between the fill end and the interference region and, in a fill configuration, the fill opening is positioned within the balloon device such that fluid entering the fill end exits at the fill opening into the balloon device, where application of the pulling force that overcomes a sliding resistance causes movement of the fill opening and the interference region into the jacket member creates a sealed configuration to seals to seal the balloon device.

### Claim 2 (depends on 1)

The valve assembly of claim 1, wherein the interference region comprises one or more regions of increased radial dimension on the conduit.

### Claim 3 (depends on 1)

The valve assembly of claim 1, wherein the interference region comprises one or more annular regions of increased radial dimension on the conduit.

### Claim 4 (depends on 1)

The valve assembly of claim 1, wherein the interference region includes a cylindrical plug having a portion comprising a diameter equal to or greater than an interior diameter of the conduit.

### Claim 5 (depends on 1)

The valve assembly of claim 1, wherein the interference region includes a spherical plug comprising a diameter equal to or greater than an interior diameter of the conduit.

### Claim 6 (depends on 1)

The valve assembly of claim 1, wherein the interference region comprises at least one bulge, the at least one bulge is configured to increase a force required to move the interior section into the jacket member.

### Claim 7 (depends on 1)

The valve assembly of claim 1, wherein a portion of the conduit and the interior channel are sized to create a sliding resistance therebetween.

### Claim 8 (depends on 1)

The valve assembly of claim 1, wherein the conduit further comprises a weakened section, the weakened section configured to break subsequent to the interference region abutting the engagement member.

### Claim 9 (depends on 1)

The valve assembly of claim 1, wherein the jacket member comprises an elongated cylindrical shape.

### Claim 10 (depends on 1)

The valve assembly of claim 1, wherein the jacket member has an inner diameter smaller than an outer diameter of the conduit.

### Claim 11 (depends on 1)

The valve assembly of claim 1, wherein the engagement member includes at least one continuous ridge around an inner diameter of the jacket member.

### Claim 12 (depends on 1)

The valve assembly of claim 1, wherein the engagement member includes a plurality of projections spaced apart within the interior channel.

### Claim 13 (depends on 12)

The valve assembly of claim 12, wherein the plurality of projections each comprise an asymmetrical shape.

### Claim 14 (depends on 1)

The valve assembly of claim 1, wherein a friction fit between the conduit and the interior channel of the jacket member creates a resistance between the conduit and interior channel of the jacket member that permits movement of the balloon device upon pulling the conduit.

### Claim 15 (depends on 1)

The valve assembly of claim 1, wherein the wall anchor comprises a lip, the lip preventing the jacket member from entering an interior of the balloon device.

### Claim 16 (depends on 1)

The valve assembly of claim 1, wherein the wall anchor comprises a flared end.

### Claim 17 (depends on 1)

The valve assembly of claim 1, wherein the wall anchor comprises a plurality of projections extending from an inner surface of the wall anchor.
