Abstract: Implantable tube, for heating by conduction a heat transfer fluid for injection into all or part of a human or animal tissue, is provided with a wall having distal, median and proximal parts and comprising connecting elements for direct or indirect connection of the distal part to a fluid reservoir, and two means for connection to the terminals of an electric power supply, for incoming and outgoing current in the wall. The tube has a resistance less than 0.01? in its median and proximal parts, and a resistance of between 0.2 and 2? in its distal part. The median and proximal parts are connected electrically in series to the distal part; the tube having no additional electrical resistance.

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 ?m and 1,000 ?m and internal diameter between 100 ?m and 500 ?m, 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.
