1. An apparatus for separating facial tissue planes and altering the tissue, comprising:
- a hollow shaft having a distal end and a proximal end;
a plurality of protruding members on the distal end of the shaft separated by at least one interstitial lysing segment, wherein the lysing segment is recessed relative to the protruding members;
at least one optical window in the shaft; and
a means for delivering laser light from the proximal end of the shaft to the distal end so that light can be transmitted through the window to targeted tissue, wherein said plurality of protruding members extend from said distal end beyond said at least one optical window.

Abstract
A device is described that can be used by surgeons to provide quick and accurate face-lifting maneuvers that minimize the amount of tissue that has to be removed. The device comprises of a hollow undermining shaft with specially designed tip that can safely separate tissue planes and lyse fibrous tissue. Laser light can be delivered down the shaft to heat and cause tissue contraction. Device can also include a temperature sensor that can be used to control laser power. Optionally the device can also use ultrasound or electrosurgical energy to improve tissue lysing.
