    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 The shaft, ground plane electrode and needle electrode are retracted into the cannula, and withdrawn from the surgical site.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 electrosurgical system is provided and includes a power source, a microwave applicator, a switching mechanism and a controller. The power source is configured to generate microwave energy. The microwave applicator is configured to deliver microwave energy from the power source to tissue. The switching mechanism includes a housing having input and output ports. The input port is connectable to the power source and the output port is connectable to the microwave applicator. The housing is configured to house one or more switches therein. The controller is in operative communication with the switching mechanism to toggle the switch from a first state, wherein microwave energy generated by the power source is directed to the microwave applicator to a second state, wherein microwave energy is directed to a resistive load operably coupled to the switching mechanism.

    摘要: An electromagnetic surgical ablation probe having a conical hood reflector and method of manufacture thereof is disclosed. The disclosed probe includes a shaft assembly that has a coaxial feedline core having an inner conductor and an outer conductor separated by an insulating layer. A tubular catheter is disposed coaxially around the feedline and is configured to deliver coolant, such as saline or deionized water, to a coolant chamber at a distal end formed within the conical reflector. A radiating section disposed within the conical reflector may have a conical, cylindrical, or other suitable shape. A membrane disposed across a distal opening of the conical reflector seals coolant within the coolant chamber, and may conform to tissue contours during use. A resilient aperture may be included at the periphery of the conical hood. The shaft assembly may include an angled section, an adjustable section, and, additionally or alternatively, a malleable section.
