    Abstract: A thermal ablation probe having one or more sensors for sensing at least one tissue parameter, such as temperature, fluctuation in temperature change, and/or rate of temperature change. The thermal ablation probe includes an elongated shaft and a head portion at a distal end of the elongated shaft. The head portion includes a sensing system having sensors for sensing the tissue parameter. The head portion further includes one or more antennas configured to apply energy to tissue. The proximal end of the thermal ablation probe is configured for removable engagement with a thermal ablation system. The one or more sensors form at least one thermal ablation probe array or sensing platform. The array(s) can be in operative communication with a control system for controlling the operation of the thermal ablation system in accordance with the at least one tissue parameter.

    Abstract: An ablation device includes a handle assembly including a distal end and a probe extending distally from the distal end of the handle assembly. The probe includes a heat-transfer portion and at least one fluid-flow path in fluid communication with the heat-transfer portion. The handle assembly includes at least one fluid reservoir in fluid communication with the at least one fluid-flow path and at least one apparatus configured to cause fluid flow between the at least one fluid reservoir and the heat-transfer portion. The probe is configured to apply thermal energy released by an exothermic chemical reaction that occurs when fluid from the at least one fluid reservoir is caused to flow to the heat-transfer portion.

    Abstract: 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.

    Abstract: According to one aspect of the present disclosure, a microwave antenna assembly is disclosed. The antenna assembly includes a feedline having an inner conductor, an outer conductor and an inner insulator disposed therebetween and a radiating portion including a dipole antenna having a proximal portion and a distal portion. The antenna assembly also comprises a sheath disposed over the feedline and the radiating portion defining a chamber around the feedline and the radiating portion. The chamber is adapted to circulate coolant fluid therethrough. The antenna assembly further includes a connection hub having cable connector coupled to the feedline, an inlet fluid port and an outlet fluid port. The connection hub includes a bypass tube configured to provide for flow of the coolant fluid from the cable connector directly to the outlet fluid port.
