1. A probe for tissue-edge characterization, comprising:

  • a first inner conductor, which comprises;

    proximal and distal ends, with respect to a tissue edge, along an x-axis;

    a first sharp edge, located at the proximal end;

    at least one feature, issuing from the first inner conductor, at the proximal end, for forming at least one additional sharp edge, operative to enhance localized electrical fringe fields in the tissue, within a predefined tissue volume, at the tissue edge, the tissue volume being defined by physical parameters associated with the at least one feature; and

    a dielectric material, which encloses the conductor, in the y-z planes;

    wherein the probe is associated with a resecting tool.
