Patent ID: 7753871

Claim:
Apparatus for injecting pulsed steam into a human or animal comprising: an injection unit ( 1 ) sending pulses of cold water into a handpiece ( 5 ), a handpiece ( 5 ) temporarily attached to the injection unit ( 1 ) within which is a metal tube ( 10 ) in which the cold water is transformed into steam, a means of distributing the steam intended to be connected in a reversible manner to the distal end of the handpiece, characterized in that the metal tube ( 10 ): has an external diameter between 200 μm and 1,000 μm and an internal diameter between 100 μm and 500 μm, has a distal end coiled to form a spiral ( 12 ), and in that two extremities of the tube are connected to an electric supply ( 27 , 15 ), the portion of the tube between its proximal end ( 19 ) and the proximal end ( 20 ) of the spiral ( 12 ) being sheathed with a material of resistivity such that only the spiral heats to a temperature allowing the water to change from the liquid to the vapor phase.
