1. An apparatus for removal of fatty tissue, comprising:
- a hollow cannula;
a substantially rigid enclosure on said cannula, said enclosure being shaped to enclose an active area within said cannula, and protect said active area from intrusion by surrounding tissues;
a water source on said cannula, said water source being disposed to release water into said active area enclosed within said cannula;
a laser source on said cannula, said laser source being disposed to impinge laser energy on said water from said water source in said active area enclosed within said cannula, to energize said water molecules, said laser source being arranged relative to said water source and said enclosure so as to prevent escape of any laser energy from said enclosure prior to impingement of said laser energy upon said water molecules;
an opening in said enclosure, said opening being positioned to allow said energized water molecules to escape from said enclosure to contact and break down surrounding fatty tissues; and
a suction port on said cannula for aspirating liquid material resulting from breakdown of surrounding fatty tissues.

Abstract
A liposuction cannula having a water source, a laser source, and a suction source. Water is released into an active area within the cannula, and laser energy is directed onto the water molecules within the active area to energize the water molecules. The energized water molecules escape from the active area into the surrounding fatty tissue to break down the fatty tissue and release liquid fatty material, which is removed by aspiration via the cannula.

6. A method for removal of fatty tissue, said method comprising:
-
providing a hollow cannula having a substantially rigid enclosure, a water source, a laser source, and a suction port; releasing water molecules from said water source into an active area enclosed within said rigid enclosure within said cannula; impinging laser energy from said laser source onto said water molecules from said water source in said active area enclosed within said cannula, to energize said water molecules, without allowing escape of any laser energy from said enclosure prior to impingement of said laser energy upon said water molecules; allowing said energized water molecules to escape through openings in said enclosure to contact and break down surrounding fatty tissues; and aspirating liquid material resulting from breakdown of surrounding fatty tissues, via said suction port. - View Dependent Claims (7, 8)
