Abstract
Apparatus intended for the injection of pulsed steam into a human or animal vessel comprising an injection unit sending pulses of cold water into a handpiece, a handpiece temporarily attached to an injection unit within which there is a metal tube, of external diameter between 200 μm and 1,000 μm and internal diameter between 100 μm and 500 μm, the metal tube having its distal end coiled to form a spiral, the tube being sheathed with a material of resistivity such that only the spiral heats to a temperature transforming water from the liquid phase into the vapor phase, a means of distributing the steam into the vessel intended to be connected in a reversible manner to the distal end of the handpiece.
Claims10
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.
