摘要： A surgical ablation system employing an ablation probe having a deployable ground plane is disclosed. The disclosed system includes a source of ablation energy and a source of electrosurgical energy, and a switching assembly configured to select between ablation and electrosurgical modes. The probe includes a cannula having a shaft slidably disposed therein. The shaft includes a deployable ground plane electrode assembly and a needle electrode disposed at distal end of the shaft. As the shaft is extended distally from the cannula, the ground plane electrode unfolds, and the needle electrode is exposed. Electrosurgical energy is applied to tissue via the needle electrode to facilitate the insertion thereof into tissue. Ablation energy is applied to tissue via the needle electrode to achieve the desired surgical outcome. The shaft, ground plane electrode and needle electrode are retracted into the cannula, and withdrawn from the surgical site.

摘要： An ablation probe having a ground plane is disclosed. The disclosed probe includes an inner conductor coaxially disposed within an outer shield. One or more ground plane(s) oriented substantially transversely to a longitudinal axis of the probe are joined to the outer shield. One or more dielectric(s) may be disposed around the inner conductor or upon a surface of a ground plane. The probe may include a rigid or flexible catheter disposed around the outer shield to define a conduit therebetween to enable the delivery of pressurized fluid to an inflatable balloon disposed around a ground plane. A semicylindrical housing having a circumferential surface and a distal surface may be included. A proximal edge of the circumferential surface of the semicylindrical housing may be joined to a circumferential edge of a ground plane. An opening may be defined in the distal surface of the semicylindrical housing, through which the inner conductor may extend distally.
