Abstract

The waveguide output for an ultrasonically vibratable cutting/coagulating tool comprises a surface having a plurality of, usually at least three, longitudinally extending ripples. The effective surface area of the output is thereby increased. A central one of the ripples is comparatively sharp edged. The ripples may be disposed, in profile, along one or more chords of or along an arc of a circle substantially coaxial with the waveguide.
