Abstract
Devices and methods having a cooling material and reduced pressures to treat biological external tissue using at least one energy source are disclosed. The cooling material may be water, ethyl alcohol, and/or any other material having a vapor pressure below atmospheric pressure. The energy source may be incoherent light, coherent light, a radio frequency, ultrasound, a laser, and/or any other type of energy that can be applied through the device. The features of various embodiments of the device include the generation of positive pressure and/or negative pressure through one or more pressure conduits, the application of an object within a recess of the device, and measurements through various sensors on the device. These sensors may be monitored and/or controlled through a display element having rows and columns of pixels on the device. The device may be a handheld device or an add-on to existing devices in some embodiments, and may include skin color sensors, temperature sensors, motion sensors, vapor pressure sensors, material sensors, and/or capacitance sensors.

16. A device that applies energy to a biological external tissue, the device comprising:
-
an outer portion to form a vacuum seal of the outer portion and the biological external tissue;
a chamber encompassed by the outer portion having a pressure below atmospheric pressure to bring at least a portion of the biological external tissue into the chamber; and
a material in the chamber to vaporize at the pressure below atmospheric pressure without damaging the biological external tissue. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A method of treating an area of biological external tissue having a target using a device, comprising:
-
coating a liquid on the area;
applying a first positive pressure on the area;
applying a negative pressure on the area to bring the biological external tissue closer to the device that is above the area;
forming a pressure equal to or lower than a vapor pressure of the liquid;
applying an energy to the target before the blood concentration in the area returns to at least a normal state; and
applying a second positive pressure on the area to allow the device to be released from the area before the biological external tissue is damaged. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34)

35. A method for treating a target with a device, the method comprising:
-
depositing a material on an area of a biological external tissue having the target;
applying the device to the area;
applying a negative pressure on the area to bring the biological external tissue into contact with a protruding object of the device that is above the area; and
applying an energy to the area before the blood concentration in the area returns to at least a normal state, and causing the material to evaporate. - View Dependent Claims (36, 37)

38. A system to treat biological external tissue using a device, comprising:
-
means for reducing temperature of an area of biological external tissue having a target by depositing a material on the area;
means for applying a negative pressure on the area to bring the biological external tissue into contact with the device; and
means for applying an energy to the target before the blood concentration in the area returns to at least a normal state. - View Dependent Claims (39, 40)
