## Abstract

A valve may have a fluid inlet and a fluid outlet. The valve may include a valve stem having a lumen extending from a first opening at a proximal portion of the valve stem to a second opening at a distal end of the valve stem. A plurality of seals may be positioned relative to the valve stem. The valve stem and seals may be configured so that a fluid entering the inlet is prevented from flowing to the outlet in a first position of the valve stem and relative to the inlet and the outlet. The valve stem and the seals may be configured so that a fluid entering the inlet flows to the outlet in a second position of the valve stem relative to the inlet and the outlet, the second position being more distal than the first position relative to the inlet and the outlet.

## Claims

### Claim 1

A medical device, comprising:
a valve stem having a proximal end, a distal end, and a radial outer surface, the valve stem comprising:
a first opening;
a second opening;
a lumen in fluid communication with the first opening and the second opening; and
one or more external threads,
wherein the one or more external threads are configured to engage a valve cylinder to longitudinally and rotationally adjust a position of the valve stem in response to a rotational force applied to the valve stem.

### Claim 2 (depends on 1)

The medical device of claim 1, wherein the one or more external threads are on the radial outer surface of the valve stem.

### Claim 3 (depends on 1)

The medical device of claim 1, wherein the second opening is proximal of the first opening and the one or more external threads are located proximal of the second opening.

### Claim 4 (depends on 1)

The medical device of claim 1, wherein the first opening is a distal opening axially aligned with a longitudinal axis of the lumen.

### Claim 5 (depends on 1)

The medical device of claim 1, wherein the first opening faces radially outward through the radial outer surface.

### Claim 6 (depends on 1)

The medical device of claim 1, wherein the second opening faces radially outward through the radial outer surface.

### Claim 7 (depends on 6)

The medical device of claim 6, wherein the first opening is a distal opening axially aligned with a longitudinal axis of the lumen and the valve stem further comprises a third opening facing radially outward through the radial outer surface at a location between the first opening and the second opening.

### Claim 8 (depends on 1)

The medical device of claim 1, further comprising:
a seal on the radial outer surface and circumferentially surrounding the first opening.

### Claim 9 (depends on 1)

The medical device of claim 1, further comprising:
a seal on the radial outer surface at a location between the first opening and the second opening, the seal is configured to seal around a perimeter of a fluid opening of a valve cylinder configured to receive the valve stem.

### Claim 10 (depends on 9)

The medical device of claim 9, wherein the seal is disc-shaped without a radially inner opening.

### Claim 11

A method, the method comprising:
delivering air from an air inlet in a valve cylinder to an air outlet in the valve cylinder while a valve stem in the valve cylinder is in a first position relative to the valve cylinder;
rotating the valve stem in the valve cylinder to a second position relative to the valve cylinder in which a first opening of the valve stem is aligned with a water inlet of the valve cylinder and a second opening of the valve stem is aligned with the air outlet; and
delivering water from the water inlet to the air outlet via the first opening and the second opening while the valve stem is in the second position.

### Claim 12 (depends on 11)

The method of claim 11, wherein rotating the valve stem longitudinally and radially adjusts the valve stem relative to the valve cylinder.

### Claim 13 (depends on 11)

The method of claim 11, wherein:
the water from the water inlet is blocked from traveling to the air outlet and a water outlet of the valve cylinder when the valve stem is in the first position; and
a seal of the valve stem seals around a perimeter of the air inlet when the valve stem is in the second position.

### Claim 14

A medical device, comprising:
a valve stem having a proximal end, a distal end, and a radial outer surface, the valve stem comprising:
a first opening;
a second opening;
a lumen in fluid communication with the first opening and the second opening; and
one or more external threads,
wherein the second opening faces radially outward through the radial outer surface, and
wherein the first opening is a distal opening axially aligned with a longitudinal axis of the lumen and the valve stem further comprises a third opening facing radially outward through the radial outer surface at a location between the first opening and the second opening.

### Claim 15 (depends on 14)

The medical device of claim 14, wherein the one or more external threads are configured to engage a valve cylinder to longitudinally and rotationally adjust a position of the valve stem in response to a rotational force applied to the valve stem.

### Claim 16 (depends on 14)

The medical device of claim 14, further comprising:
a valve cylinder comprising one or more fluid inlets and one or more fluid outlets, the valve cylinder configured to receive the valve stem,
wherein:
the valve stem is configured to adjust between a first position and a second position relative to the valve cylinder in response to rotation of the valve stem,
in the first position, the second opening is proximal of a fluid outlet of the one or more fluid outlets and circumferentially offset from the fluid outlet, and
in the second position, the second opening is longitudinally and circumferentially aligned with the fluid outlet.

### Claim 17 (depends on 16)

The medical device of claim 16, further comprising a seal on a radial outer surface of the valve stem at a location between the first opening and the second opening, the seal is configured to seal around a perimeter of a fluid inlet of the one or more fluid inlets when the valve stem is in the second position.

### Claim 18 (depends on 16)

The medical device of claim 16, wherein:
in the first position, the third opening is proximal of a fluid inlet of the one or more fluid inlets and circumferentially offset from the fluid outlet, and
in the second position, the third opening is longitudinally and circumferentially aligned with the fluid inlet.

### Claim 19 (depends on 14)

The medical device of claim 14, further comprising a seal extending circumferentially around the third opening on a radial outer surface of the valve stem, the seal is configured to seal around a perimeter of a fluid inlet of a valve cylinder.

### Claim 20 (depends on 19)

The medical device of claim 19, wherein the seal is disc-shaped without a radially inner opening.
