摘要： The tissue ablation device includes a tissue ablation probe having an elongated probe shaft and electrodes carried by the distal end of the probe shaft. The device further comprises a cannula with a central lumen extending along a longitudinal axis for removably receiving the probe shaft. The cannula further comprises concentric inner and outer tubes extending along the longitudinal axis, wherein the outer is tube is translatable relative to the inner tube. The inner and outer tubes further comprise inner and outer apertures, respectively, that are aligned by translating the outer tube. When the inner and outer apertures are aligned, electrodes are deployed through the inner and outer apertures. One method includes introducing a cannula and a tissue ablation probe to a tissue site and operating the tissue ablation probe and the cannula to deploy the electrodes and ablate tissue.

摘要： A RF ablation device includes a probe assembly that has an elongate cannula having a lumen disposed interiorly of an external wall of the cannula. The elongate cannula includes a plurality of slots formed within the external wall that provide access to the lumen. The probe assembly includes an electrode member that is slidably disposed within the elongate cannula, the electrode member including a plurality of tines configured for passage through the plurality of slots. The slots are disposed in a staggered arrangement or pattern about the external wall of the cannula. The staggered arrangement of slots may be used in a monopolar or bipolar arrangement of the electrodes on the cannula. A bipolar arrangement of electrodes using the staggered configuration produces larger ablation areas in a shorter period of time as compared to prior designs.

摘要： Tissue ablation systems and methods are provided. Ablation energy (e.g., radio frequency energy) is delivered to the tissue and a physiological parameter (e.g., impedance and/or temperature) indicative of a change in moisture concentration of the tissue is sensed. The ablation energy is alternately pulsed on and off to generate an energy pulse train, with the ablation energy being pulsed on if the sensed physiological parameter crosses a threshold value indicative of an increase in the moisture concentration, and being pulsed off if the sensed physiological parameter crosses a threshold value indicative of a decrease in the moisture concentration.
