Device and Method for Injecting Pulsed Steam Into a Human or Animal Vessel E.G. a Vein

A device for injecting pulsed steam into human or animal vessel including:

• a water pulse generator that produces micro pulses of pressurized sterile water;
• a hand piece that transforms pulses of water coming from the generator into pulses of steam;
• an endoluminal catheter for delivering the steam into the vessel;
• connection means between the hand piece and the endoluminal catheter;
• and a programmable central processing unit (cpu) to control the water pulse generator and the handpiece;
• wherein
• a. the endoluminal catheter comprises a tubular part which length L (in cm) is comprised between the following ranges (limits included) given in an increasing order of preference:
• [1;
• 30], [2;
• 28], [3;
• 27], [4;
• 26], [5;
• 25], [6;
• 24], [8;
• 22], [10;
• 20];
• b. the tubular part of the endoluminal catheter is made of a flexible, biocompatible, thermically insulating and thermically resistant material, preferably of a non-metallic material, more preferably a polymer;
• c. the distal end of the endoluminal catheter has a terminal and central opening.
