Abstract: Device for administering heat to a cavity, tissue or vessel, characterised in that it takes the form of an insulated copper wire over the length of which is crimped a tube having a resistivity of more than 20 ??·cm, the copper wire (1) is in contact with the said tube at its distal extremity, the tube is enclosed over part of its length by at least one movable cylinder having an electrical resistance of less than 20 ??·cm, and the movable cylinder and the copper wire have means for connection to a current generator.

Abstract: An installation for delivering calories to all or part of human or animal cell tissue via a liquid comprises: a heating unit heating the liquid; an injection unit injecting the liquid into the heating unit; a dispenser for dispensing the heated liquid; and a transporter for transporting the liquid from the heating unit to the dispenser. The installation allows the heated liquid to be dispensed from the dispensing means in a pulsed operation.

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.

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: A device for locking a workpiece in position on a working plane for a machining operation. The device includes a column to be mounted to extend perpendicularly from such a working plane, and a locking assembly slidably displaceable along the column. The locking assembly includes two gripping members positioned in opposed relationship on opposed sides of the column for each gripping member to partially embrace the column; a pressure member displaceably connected to the gripping members to extend therefrom and to be displaceable relatively thereto; and means operable by means of a single control lever to displace the two gripping members towards each other to tighten onto the column, and to cause the pressure member to swivel relatively to the gripping members for locking a workpiece in position on such a working plane.
