Laser Treatment System And Method For Producing Thermal Cavities And Energy Droplets

View page
US Patent:
20110160712, Jun 30, 2011
Filed:
Nov 2, 2009
Appl. No.:
12/590075
Inventors:
Nikolai Tankovich - San Diego CA, US
Alexei Lukashev - San Diego CA, US
International Classification:
A61B 18/20
US Classification:
606 9
Abstract:
A laser process for tissue treatment. Preferred embodiments include features for producing a first laser beam and a second laser beam and a skin cooler for cooling the surface of a region of skin. The system is designed to utilize the first laser beam for heating a volume of skin tissue below the cooled surface region to a temperature below skin tissue damage threshold. This volume of skin tissue is called a “thermal cavity”. The second laser beam is divided into a plurality of separate laser beams that are directed through separate optical fibers and via separate paths through skin tissue to a single tiny volume of skin tissue within the thermal cavity to heat that tiny volume to a temperature above the damage threshold. This tiny volume is called an energy droplet. Thus tiny regions of tissue are damaged while minimizing or preventing any significant damage to adjacent tissue.

Alexei Lukashev - San Diego CA, US
International Classification:
A61B 18/22
A61B 18/20
US Classification:
606 3, 606 9
Abstract:
A laser skin treatment process and system. The system includes features for producing a first laser beam of long pulse duration and a second laser beam of short pulse duration and a skin cooler for cooling the surface of a region of skin. The system is designed to utilize the first laser beam for heating a volume of skin tissue below the cooled surface region to a temperature to produce skin tissue modification but below skin tissue damage threshold. This volume of skin tissue is called a “thermal cavity”. The second laser beam is divided into a plurality of separate laser beams that are directed through separate optical fibers and via separate paths through skin tissue to a single tiny volume of skin tissue within the thermal cavity to produce in that tiny volume mechanical damage. This tiny volume is called an energy droplet. Thus tiny regions of tissue are damaged while minimizing or preventing any significant damage to adjacent tissue.
