Abstract: Methods are provided herein for affecting a region of a subject's body, comprising exposing the region to a cooling element under conditions effective to cool subcutaneous adipose tissue in said region; and increasing the blood flow rate to the cooled tissue by exposing the tissue to an energy source. Methods are also provided for treating subcutaneous adipose tissue in a region of a subject's body, comprising exposing said region to a cooling element under conditions effective to cool said tissue; and exposing the tissue to an energy source to increase the blood flow rate to the cooled tissue, thereby stimulating reperfusion in, and/or causing an ischemia-reperfusion injury to, the cooled tissue.

Abstract: Treatment apparatus and methods for inducing microburn patterns in tissue. The treatment apparatus comprises a delivery device positionable adjacent to the tissue and a plurality of energy-transfer elements. The energy-transfer elements are adapted to contact the skin surface over discrete surface contact areas and transfer energy to the tissue for forming damaged regions in the form of microburns at a corresponding plurality of locations in the tissue. Energy may be transferred between the energy-transfer elements and the tissue by either electrical conduction or thermal conduction. Adjacent microburns are separated by non-damaged regions, which promotes wound healing and efficacy.
