Self-actuated breast lesion probe and method

Abstract

Abstract A self-actuating breast lesion probe that comprises a wire (12) possessing a small memory hook (14) at its distal end that is adapted to anchor in tissue at the lesion site. The wire has a relatively soft flexibility characteristic whereby its distal end may release and easily slide from its anchored position in the tissue and assume a straight configuration when sheathed in a cannula (10). The wire may be provided with graduations (26) to indicate the depth of the wire when anchored in tissue. Graduations (11) also may be provided on the cannula to indicate the depth of cannula penetration into the body.
