## Abstract

A combination device for applying a treatment of light and ultrasound on a tattooed area of a patient desiring tattoo removal. The device includes an ultrasound and a LED light source. The ultrasound source produces high-frequency ultrasound waves. These waves are applied directly to the tattooed area for a first specified period of time resulting in release of tattoo ink from tattooed cells. The LED source produces a continuous high-intensity light that is applied directly over the entire tattooed area for a second specified period of time resulting in degradation of the tattoo ink.

## Claims

### Claim 1

An apparatus for applying a treatment of light and ultrasound on a tattooed area of a subject for tattoo removal, the apparatus comprising:
an ultrasound device, the ultrasound device producing a high-frequency ultrasound waves, the ultrasound device applying the high-frequency ultrasound waves directly to the tattooed area for a first specified period of time; and
ultra-bright light emitting diodes (LEDs), for producing a continuous energy output directly over the entire tattooed area for a specified period of time resulting in degradation of the tattoo ink.

### Claim 2 (depends on 1)

The apparatus of claim 1 wherein the light penetrates an epidermis of the subject without damaging the epidermis by overheating and enters a dermis of the subject in which tattoo ink resides.

### Claim 3

The apparatus of Claim I wherein the LEDs have a average wavelength between 400-700 nm resulting in (a) minimal absorption by melanin and hemoglobin of the subject and (b) little to no heat being generated on the epidermis of the subject while generating heat in the tattoo ink.

### Claim 4 (depends on 1)

The apparatus of claim 1 wherein the tight array of ultra-bright LEDs is approximately equal to size of the tattooed area.

### Claim 5 (depends on 1)

The apparatus of claim 1 wherein the tight array of ultra-bright LEDs having an energy output of about 50,000 Lux without the use of pulsed radiation.

### Claim 6 (depends on 1)

The apparatus of claim 1 wherein the second specified period of time is approximately 10-30 minutes.

### Claim 7 (depends on 1)

The apparatus of claim 1 wherein the high frequency ultrasound device administers the ultrasound sound waves with a frequency of about 5 MHz and an intensity of about 20W/cm2.

### Claim 8 (depends on 1)

The apparatus of claim 1 wherein the first specified period of time is approximately 10 minutes.

### Claim 9 (depends on 1)

The apparatus of claim 1 wherein the ultrasound sound waves are administered in intervals in order to allow tissue recovery between each interval.

### Claim 10

A method for removing tattoos comprising the steps irrespective of order:
applying an ultrasonic gel to a tattooed skin region;
positioning an ultrasonic device in direct contact with the tattooed area;
exposing the tattooed skin region to high-frequency ultrasound waves for a first specified period of time resulting in release of ink particles of tattooed cells;
positioning an optical device including a plurality of ultra bright LEDs at a specific distance from said tattooed skin region, and
exposing said tattooed skin region to continuous LED energy without pulsing in the range of 400 nm to 700 nm wavelengths for a timed interval.

### Claim 11 (depends on 10)

A method in accordance with claim 10
with the addition of the step of applying L-argirine to a tattooed skin region.
