Kit of optical fibers for percutaneous ablative treatment

A kit of optical fibers for percutaneous ablative treatment comprising:

• at least two optical fibers, each of said at least two optical fibers comprising a connector to a laser source at a first end thereof and a device for constraining a pervious needle in proximity to a second end thereof;
• a coding system that characterizes one fiber with respect to the other, allowing said fibers to be distinguished from one another, and wherein said coding system comprises for each fiber a first coding element combined to the corresponding device for constraining said fiber to the needle;
• at least two needles having characteristics differing from one another to distinguish one needle from the other, each of said needles having a coding corresponding to the coding of a respective fiber, to unequivocally couple each fiber with a respective needle corresponding thereto.
