1. A method for removing a protruding tissue from abutting engagement with a nerve, comprising the steps of:

  • undermining tissue, which protrudes into abutting engagement with a nerve, by forming a cavity adjacent said tissue;

    performing said undermining with arthroscopic tools;

    employing progressively larger dilator tubes and progressively larger cutter tubes to enlarge the cavity;

    dimensioning the cavity so that it has a volume adequate to fully receive therewithin the protruding tissue; and

    inducing the collapse of the cavity by using a laser means to heat inner disc material of the cavity so that the producing tissue falls into said cavity and out of engagement with said nerve.
