Abstract:
1. A dermatological medical device, comprising: a distal end for positioning at a region proximal a target therapeutic region of tissue; an output port at the distal end; a non-injurying heat shock treatment energy source that generates optical energy at an amount of energy, which is output from the output port to the target therapeutic region of tissue; and a control device including a microprocessor having embedded software that controls the optical energy at the target therapeutic region of tissue to have a treatment pulse width of less than 2 seconds during which a temperature of the target therapeutic region of tissue is increased at the amount of energy to a temperature that is less than a pain threshold temperature and for inducing an expression of heat shock proteins (HSPs) at the target therapeutic region of tissue, the microprocessor controlling the optical energy output from the output port to the target therapeutic region of tissue at the amount of energy for producing a temperature increase of the target therapeutic region of tissue between 2° C. and 8° C. within the treatment pulse width of less than 2 seconds to a peak temperature that is less than the pain threshold temperature, the microprocessor further controlling the optical power output from the output port to the target therapeutic region to reduce one or more first power levels related to the amount of energy to one or more second power levels within the treatment pulse width of less than 2 seconds to maintain the temperature of the region of tissue at or below the peak temperature and within a therapeutic temperature range that is less than the pain threshold temperature, the microprocessor of the controller controlling the one or more first power levels of the optical energy according to an optical power temporal profile including a maximum power density of 400 W/cm2 at a first wavelength greater than 1400 nm, and the controller further controlling the one or more second power levels of the optical energy according to the optical power temporal profile for maintaining a tissue temperature less than the pain threshold temperature at an optical energy exposure time less than 2 seconds, and providing a power density between 0.1 and 0.37 W/cm2 and at a second wavelength greater than 1400 nm that produces a thermal exposure time of 2-10 seconds to maintain the temperature increase at the target therapeutic region of tissue between 2° C. and 8° C.
