Self-contained, diode-laser-based dermatologic treatment apparatus
First Claim
1. A dermatologic treatment apparatus that is cordless and sufficiently compact as to be hand-held, comprising:
- a self-contained housing configured for gripping by a person'"'"'s hand for cordless manipulation in a dermatologic treatment procedure;
a light source comprising one or more diode laser bars within the housing;
an electrical circuit within the housing comprising one or more batteries and an electronic control circuit for energizing the light source to produce output light pulses;
a light path within the housing including an aperture through which the output light pulses are propagated out of the housing having properties that provide efficacious treatment; and
a heatsink for contacting a region of an epidermis of a person undergoing treatment, having one or more thermal characteristics that serve to remove heat from the epidermis, and wherein the temperature of the heataink is maintained below a normal skin temperature, wherein a normal skin temperature is a temperature of the skin when not being treated with the device;
wherein the cordless apparatus has a total weight of no more than one kilogram, andwherein the cordless apparatus occupies no more than 1500 cm3 of volume.
