Abstract

A device and a method for thermal treatments of target material with various thermal interactions are disclosed. A preferred treatment includes Thermal Heat Shuttle that transports a predetermined known quota of energy to the target surface. In particular, the launching of thermal energy quanta from various energy sources in lumps of energy quanta and leading to the treatment and healing of a variety of skin conditions are disclosed.

Claims

1. A device for treating skin by delivering a controlled amount of thermal energy to the skin comprising:

a hand-held enclosure; and

a heat-providing portion configured to deliver the controlled amount of thermal energy to the skin, the heat-providing portion comprising;

a flash lamp for emitting optical energy;

a reflector for directing the optical energy emitted from the flash lamp;

a circuit having a capacitor, the circuit configured to deliver a predetermined amount of energy via the capacitor to the flash lamp; and

an absorbing layer being placed between the flash lamp and the skin and capable of absorbing the optical energy discharged by the flash lamp and converting it into thermal energy;

a heat delivery surface positioned on an external portion of the device and configured to be placed against the surface of the skin, the heat delivery surface configured to transmit the thermal energy to the skin, the heat delivery surface having an area of 0.2 cm² to 4 cm²;

wherein the controlled amount of thermal energy provided to the skin is between 0.1 J/cm² and 50 J/cm², and the controlled amount of thermal energy is provided in a delivery time of less than 0.5 second.

2. The device of claim 1, wherein the absorbing layer comprises a pattern of absorbing and transmitting regions.

3. The device of claim 1, wherein the absorbing layer is supported on a transparent substrate.

4. The device of claim 1, wherein the absorbing layer is made of absorbing metal.

5. The device of claim 1, wherein the absorbing layer is made of absorbing insulator.

6. The device of claim 1, further comprising a power source electrically coupled to the capacitor of the circuit, wherein the capacitor is charged by the power source and discharged by a user-operated external trigger.

7. A method for treating skin conditions comprising:

providing a device comprising a circuit having a capacitor, wherein the circuit is configured for charging a capacitor from a power source and for releasing a pre-determined amount of energy from the capacitor, wherein the circuit comprises a power button configured to activate charging of the capacitor from the power source, and the circuit further comprises a discharge button configured to activate release of the pre-determined amount of energy from the capacitor;

providing a heating element configured to absorb at least some of the energy discharged from the capacitor and converting it to thermal energy, wherein the heating element comprises a heat transfer surface and a flash lamp configured to convert the energy discharged from the capacitor into optical energy, the heating element further comprising an absorbing substance configured to absorb optical energy from the flash lamp and convert it into thermal energy, and wherein the heat transfer surface has an area of 0.2 cm² to 4 cm²;

switching the power button to activate charging of the capacitor by the power source;

bringing the heat transfer surface adjacent to and against the skin to be treated; and

switching the discharge button to activate release of the pre-determined amount of energy from the capacitor to the heating element to thereby heat an upper layer of the skin to a temperature in the range from 50°

C. to about 400°

C., wherein the amount of thermal energy provided to the skin is between 0.1 J/cm² and 50 J/cm².

8. The method of claim 7 wherein the layer below the epidermal dermal junction remains below 50°

C.

9. The method of claim 7 wherein the layer below the mid-reticular dermis remain below about 50°

C.

10. The method of claim 7 wherein the layer below the dermal epidermal junction remains below about 50°

C. and at least some changes in the opening at the skin surface occurs.

11. The method of claim 7, wherein bringing the heat transfer surface adjacent to and against the skin comprises placing the absorbing substance adjacent the skin, the method further comprising:

disengaging the absorbing substance from the skin; and

emitting optical energy directing onto the skin.
