Photopatterning of skin
First Claim
Patent Images
1. A method of producing a patterned distribution of a material in or on skin, comprising:
- delivering a photoresponsive material to at least a skin region of a subject; and
delivering targeted light to said skin region according to a pattern, said targeted light having a wavelength content, time-averaged flux and/or fluence sufficient to cause a transformation of said photoresponsive material to a modified form.

45. A system for delivering light to skin in a pattern, comprising:
-
a light source capable of producing light of at least one defined wavelength band;
memory capable of storing a pattern in machine-readable form representing a plurality of locations within a skin region to which light from said light source is to be directed;
a controllable positioning system configured to adjust the positioning of light from said light source on a skin region;
one or more optical components capable of focusing light from said light source at a specific depth within a skin region in response to a control signal; and
a controller configured to generate a control signal for driving said controllable positioning system to direct light onto a plurality of skin locations according to the pattern stored in said memory. - View Dependent Claims (46, 47, 50, 68)

55. A method of producing a patterned distribution of a material within a skin region, comprising:
-
delivering a photoresponsive material to a skin region of a subject in a first pattern; and
delivering targeted light to the skin region in a second pattern, said second pattern overlapping partially with said first pattern, wherein photoresponsive material in the areas of overlap between said first pattern and said second pattern undergoes photomodification to form an overlap pattern of modified photoresponsive material within said skin region. - View Dependent Claims (71)
