Abstract:
1. A device for thermally separating collagen containing tissue, comprising: a laser device having a programmed light beam profile for a predetermined closed curve to be directed at a tissue, wherein said tissue contains: (i) collagen and (ii) a light-absorbing agent, wherein said predetermined closed curve defines an interior and an exterior area, wherein said programmed light beam profile is selected with the intent that said programmed light beam profile is absorbed by said light-absorbed agent to cause a local thermal effect at said tissue and therewith said light beam profile is characterized to: (j) remain at a sub-ablation level for said tissue, and (jj) transition the collagen in said tissue from a crystalline helixcal structure to an amorphous structure resulting in shrinkage or contraction of said tissue, wherein said programmed light beam profile is programmed to be directed at an initial and interior point of said predetermined closed curve, and further programmed to be continued and directed starting from said initial and interior point of said predetermined closed curve along a remaining path of said predetermined closed curve until at least the curve is closed, wherein said tissue is to be thermally separated as a result of said programmed light beam profile executed by said laser device.
