(54) Title: ELECTROSURGICAL ENERGY CONVEYING STRUCTURE AND ELECTROSURGICAL DEVICE INCORPO- RATING THE SAME 100 FIG. 1 (57) : An energy conveying structure for invasive electrosurgery that provide for combined delivery of (i) RF or microwave electromagnetic energy for tissue treatment (e.g. ablation, coagulation or cutting), and (ii) optical radiation within a common structure that may form an instrument cable of a surgical scoping device. The structure resembles a hollow coaxial transmission line with an optical channel formed within it. The optical channel can lie within a passage that is formed within the inner conductive layer or within other layers of the coaxial transmission. The structure may be used to form an electrosurgical device capable of delivering RF/ microwave EM energy, optical radiation and ultrasonic signals to a treatment site along an instrument cable of a surgical scoping device.
