1. A method for using a laser beam in stereotactic laser neurosurgery for the photodisruption of malignant tissue which comprises the steps of:

  • locating a hollow probe to establish extracorporeal access to the tissue to be photodisrupted, said hollow probe having a proximal end and a distal end and being formed with a channel;

    selectively placing a light reflector near said distal end of said probe;

    directing said laser beam on a beam path through said channel of said probe for reflection from said light reflector in a direction away from said beam path;

    positioning a lens in said channel proximal to said light reflector to focus said laser beam at a desired focal point;

    moving said light reflector, in concert with movement of said lens, to move said focal point in a predetermined manner for photodisruption of the tissue;

    rinsing said light reflector with a solution; and

    aspirating said solution together with photodisrupted debris from around said tissue.
