## Abstract

A vocal fold movement translation device includes a reverse motion linkage configured to interface with a first vocal fold and a second vocal fold. The reverse motion linkage includes a mechanical component configured to move the first vocal fold in a first movement direction in response to movement of the second vocal fold in a second movement direction that is opposite the first movement direction. The reverse motion linkage is movable between a first configuration corresponding to an abducted position of the first and second vocal folds and a second configuration corresponding to an adducted position of the first and second vocal folds.

## Claims

### Claim 1

A vocal fold movement translation device, comprising:
a reverse motion linkage configured to interface with a first vocal fold and a second vocal fold, wherein the reverse motion linkage includes a mechanical component configured to move the first vocal fold in a first movement direction in response to movement of the second vocal fold in a second movement direction that is opposite the first movement direction;
wherein the reverse motion linkage is movable between a first configuration corresponding to an abducted position of the first and second vocal folds and a second configuration corresponding to an adducted position of the first and second vocal folds.

### Claim 2 (depends on 1)

The vocal fold movement translation device of claim 1, wherein the reverse motion linkage includes a first lever configured for attachment to a first cartilage supporting the first vocal fold and a second lever configured for attachment to a second cartilage supporting the second vocal fold.

### Claim 3 (depends on 2)

The vocal fold movement translation device of claim 2, wherein the reverse motion linkage includes a single linkage mechanism interconnecting the first and second levers.

### Claim 4 (depends on 3)

The vocal fold movement translation device of claim 3, wherein the single linkage mechanism includes a rack and pinion mechanism.

### Claim 5 (depends on 4)

The vocal fold movement translation device of claim 4, wherein the first lever includes a first toothed rack portion and the second lever includes a second toothed rack portion, wherein the first toothed rack portion is in mesh with a first pinion gear and the second toothed rack portion is in mesh with a second pinion gear.

### Claim 6 (depends on 5)

The vocal fold movement translation device of claim 5, wherein the first vocal fold corresponds to a non-working vocal fold and the second vocal fold corresponds to a working vocal fold, wherein, during a rotation of the first and second pinion gears, a travel distance of the second lever is greater than a travel distance of the first lever.

### Claim 7 (depends on 5)

The vocal fold movement translation device of claim 5, wherein the first and second pinion gears are supported on a housing at a common axis of rotation, wherein the housing is configured for attachment to a laryngeal wall.

### Claim 8 (depends on 3)

The vocal fold movement translation device of claim 3, wherein the single linkage mechanism includes a center lever supported on a housing at a fixed pivot axis, wherein a first end of the center lever is movably attached to the first lever at a first movable pivot axis and a second end of the center lever is movably attached to the second lever at a second movable pivot axis.

### Claim 9 (depends on 8)

The vocal fold movement translation device of claim 8, wherein the first vocal fold corresponds to a non-working vocal fold and the second vocal fold corresponds to a working vocal fold, wherein the fixed pivot axis is closer to the first movable pivot axis than the second movable pivot axis.

### Claim 10 (depends on 8)

The vocal fold movement translation device of claim 8, wherein the housing is configured for attachment to a laryngeal wall.

### Claim 11 (depends on 2)

The vocal fold movement translation device of claim 2, wherein the reverse motion linkage includes two linkage mechanisms.

### Claim 12 (depends on 11)

The vocal fold movement translation device of claim 11, wherein each of the two linkage mechanisms includes a center lever supported on a housing at a fixed pivot axis, wherein the center lever is movably attached to the first lever at a first movable pivot axis and movably attached to the second lever at a second movable pivot axis.

### Claim 13 (depends on 12)

The vocal fold movement translation device of claim 12, further including a spring mechanism configured to bias the reverse motion linkage toward the first configuration.

### Claim 14

A method of operating a vocal fold movement translation device, comprising steps of:
interfacing with a non-working vocal fold and a working vocal fold using a reverse motion linkage of the vocal fold movement translation device;
receiving an indication of a movement of the working vocal fold in a first movement direction at the reverse motion linkage; and
moving the non-working vocal fold in a second movement direction using a mechanical component of the reverse motion linkage in response to the movement of the working vocal fold, wherein the second movement direction is opposite the first movement direction.

### Claim 15 (depends on 14)

The method of claim 14, further including moving the reverse motion linkage between a first configuration corresponding to an abducted position of the non-working and working vocal folds and a second configuration corresponding to an adducted position of the non-working and working vocal folds.

### Claim 16 (depends on 15)

The method of claim 15, further including:
attaching a first lever to a first cartilage supporting the non-working vocal fold and attaching a second lever to a second cartilage of the working vocal fold; and
interconnecting the first and second levers through a linkage mechanism.

### Claim 17 (depends on 16)

The method of claim 16, further including translating a travel distance of the second lever into a travel distance of the first lever using a rack and pinion mechanism.

### Claim 18 (depends on 16)

The method of claim 16, further including translating a travel distance of the second lever into a travel distance of the first lever using a center lever having a fixed pivot axis, wherein the center lever is movably attached to the first lever at a first movable pivot axis and movably attached to the second lever at a second movable pivot axis.

### Claim 19 (depends on 16)

The method of claim 16, further including biasing the reverse motion linkage toward the first configuration.

### Claim 20 (depends on 16)

The method of claim 16, further including attaching a housing of the linkage mechanism to a laryngeal wall.
