## Abstract

A device for percutaneous delivery of therapeutic agents includes a first wheel having an axis of rotation, a first axial surface rotably mounted on the head, a second axial surface, an outer surface, and a plurality of needles disposed upon the outer surface, each needle having a tip projecting away from the axis of rotation of the wheel. The device includes a second wheel having an axis of rotation, a first axial surface affixed to the second axial surface of the first wheel, a second axial surface, an outer surface, and a plurality of needles disposed upon the outer surface, each needle having a tip projecting away from the axis of rotation.

## Claims

### Claim 1

A device for percutaneous delivery of therapeutic agents, the device comprising:
a head mounted on a body, said head comprising at least one projection;
a first wheel having an axis of rotation, a first axial surface of the first wheel comprising a central cavity that engages with said projection such that the first axial surface of the first wheel is rotably mounted on the head, a second axial surface of the first wheel, an outer surface, and a plurality of needles disposed upon the outer surface, each needle having a tip projecting away from the axis of rotation of the wheel;
a second wheel having an axis of rotation, a first axial surface of the second wheel coupled to the second axial surface of the first wheel, a second axial surface of the second wheel, an outer surface, and a plurality of needles disposed upon the outer surface, each needle having a tip projecting away from the axis of rotation;
a reservoir mounted on the body, wherein the reservoir is contained in a tube having a bottom end near to the wheel and a top end, wherein an opening is in the bottom end of the tube; and
a plunger within the tube, and an actuator button set through the tip end of the tube and mechanically linked to the plunger, such that depression of the actuator button causes the plunger to force the fluid out through the opening.

### Claim 2 (depends on 1)

The device of claim 1, wherein the opening further comprising a slit valve disposed across the opening that prevents the fluid from passing through the opening when the device is not in use.

### Claim 3 (depends on 1)

The device of claim 1 wherein each of the plurality of needles mounted on the outer surface of the first wheel has a first length and each of the plurality of needles mounted on the outer surface of the second wheel has a second length, the second length differing from the first length.

### Claim 4 (depends on 1)

The device of claim 1, wherein the first axial surface of the second wheel has at least one mortise, and the second axial surface of the first wheel has at least one tenon fitting in the at least one mortise.

### Claim 5 (depends on 1)

The device of claim 1, further comprising a third wheel having an axis of rotation, a first axial surface of the third wheel affixed to the second axial surface of the second wheel, a second axial surface of the third wheel, an outer surface, and a plurality of needles disposed upon the outer surface, each needle having a tip projecting away from the axis of rotation.

### Claim 6 (depends on 5)

The device of claim 5 wherein each of the plurality of needles mounted on the outer surface of the first wheel has a first length, each of the plurality of needles mounted on the outer surface of the second wheel has a second length, and each of the plurality of needles mounted on the outer surface of the third wheel has a third length.

### Claim 7 (depends on 6)

The device of claim 6, wherein the first length differs from the second length.

### Claim 8 (depends on 6)

The device of claim 6, wherein the first length differs from the third length.

### Claim 9 (depends on 6)

The device of claim 6, wherein the second length differs from the third length.

### Claim 10 (depends on 6)

The device of claim 6, wherein the third wheel has a central cavity on its second axial surface that engages with said projection on said head and is rotably mounted on the head.

### Claim 11 (depends on 1)

The device of claim 1, wherein the second axial surface of the second wheel comprising a central cavity engages with said projection such that the second axial surface of the second wheel is rotably mounted on the head.
