The shaft (150) extends distally from the handle (25) and includes a coaxial feedline (153), a wire conduit (162) disposed along a longitudinal axis of the shaft (150), and a pull wire (163) disposed within the wire conduit (162) and having a proximal and a distal end, wherein a proximal end of the pull wire (163) is operably coupled to the actuator 1o (60). The aperture assembly (200) is coupled to a distal end of the shaft (150) and includes a reflector (200) having a closed upper portion (201), and an open lower portion (202) from which the blade (210) may be extended for use. Also disclosed is an ablation system (10) that includes the above-described ablation instrument (100), a source of ablation energy (20), and optionally, a source of coolant (18) for cooling the shaft (150) is and aperture assembly (200).1/9 LO~ .C-C% /C /L LO/ co -- -- -- - - -- -- - C CD/ C)/ /L /L Ul/ /OC. /O C.0 C)~ co/ C)/
