ABSTRACT:
A device is described that can be used quickly and accurately by surgeons to provide uniform facial tissue planes that are tunnel-free and wall-free thus optimizing face lifting, tightening, and implant delivery. The device is comprised of a shaft with a substantially planar tip further comprised of relative protrusions and energized relative recession lysing segments. Forward motion of the device precisely divides and energizes various tissue planes causing contraction, especially via the fibrous tissues. Other forms of energy and matter can be delivered down the shaft to further enhance desirable tissue modification and contraction.
