Patent abstract
A tissue dissector and method for welding and severing blood vessels includes advancing the tip of a tissue-dissecting surgical instrument through tissue, with a tissue welder substantially concealed within the tip during tissue dissection. Blood vessels encountered in the tissue being dissected are selectively captivated and compressed in substantial contact with the tissue welder to elevate the temperature of the compressed tissue sufficiently to hemostatically weld and sever the compressed blood vessel.
