  • System and method for control of tissue welding
    Patent number: 6733498
    Abstract: A system and method for welding of biological tissue by applying an RF voltage during a first stage to electrodes of a tissue welding tool; monitoring tissue impedance, and determining a minimum tissue impedance value during the first stage; determining relative tissue impedance; detecting when the relative tissue impedance reaches a predetermined relative tissue impedance value and starting a second stage; calculating the duration of the second stage as a function of the duration of the first stage; and applying the RF voltage during the second stage to the electrodes of the tissue welding tool.
    Type: Grant
    Filed: February 19, 2002
    Date of Patent: May 11, 2004
    Assignee: Live Tissue Connect, Inc.
