1. Apparatus for bonding an incision or split in soft biological tissue, the incision or split dividing the tissue into first and second portions, the apparatus comprising:

  • a first electrode to contact the first portion of the tissue;

    a second electrode to contact the second portion of the tissue;

    means to apply pressure to the first and second electrodes to grip the first and second portions of the tissue;

    an electrical power source for providing a high frequency electrical signal to said electrodes to be passed through said first and second portions of said tissue; and

    control means coupled to said electrical power source to provide said electrodes with one voltage signal during a first of two stages, and another voltage signal during a second of said two stages, wherein the voltage signal during the second stage is sustained at a constant level equivalent to a maximum voltage of the first stage voltage signal to provide tissue welding that forms a weld to reconnect the tissue.
