1. An improved electrosurgery electrode for cooperation with an electrode holder connected to a source of electrical power and with an introducer catheter, comprising in combination:

  • a solid electrode shaft having a first and a second end;

    a shaft connecting means for electrically connecting said first end of said electrode shaft to the electrode holder;

    an electrode tip having a proximal and distal end;

    said distal end of said electrode tip comprising a hook extending generally perpendicular from an axis extending through said electrode shaft;

    a tip connecting means for electrically connecting said proximal end of said electrode tip to said second end of said electrode shaft thereby electrically connecting said distal end of said electrode tip;

    said distal end of said electrode tip extending beyond the surface of said electrode shaft a distance generally equal to or less than the radius of said electrode shaft thereby enabling said electrode tip to pass through the introducer catheter; and

    insulating means for providing electrical insulation and abrasion resistance between an exposed portion of said electrode tip and said shaft connecting means and for forming a substantially waterproof seal when said first end of said electrode shaft is connected to the electrode holder.
