Electrosurgical forceps for delivering microwave energy into biological tissue from a non-resonant unbalanced lossy transmission line structure located within or formed by the jaws of the forceps. The transmission line structure may be formed across the gap between the jaw element by opposed conductive elements 104, 106, which are respectively electrically connected to inner and outer 108 conductors of a coaxial cable 102. Alternatively, each jaw element 104, 106 may comprise its own lossy transmission line, whereby a power splitter is used to divide microwave energy from the coaxial cable 102. |
