Abstract
Abstract A device for separating subcutaneous tissue and for tightening and contracting internal dermal tissue. In particular, the device uses an elongated hollow shaft having a distal end that has an ultrasonic energy source that projects ultrasonic energy outward at the distal end of the device to lyse through the subcutaneous fat tissue, and associated fiber optics and lens that projects laser beams outward to irradiate the internal dermal tissue.
