摘要： A tissue ablation system including numerous components and methods is described herein for encircling target tissue and generating tissue ablation volumes in various biological tissues. The biological tissue includes tissue of a variety of organs of the human body including the liver, spleen, kidney, lung, breast and other organs, but is not so limited. The tissue ablation device comprises an energy source and at least one trocar coupled to the energy source, the trocar having a body, a proximal end, and a distal end. The trocar carries an electrode array that comprises a plurality of electrodes, each electrode of the plurality of electrodes is configured to extend from the trocar when moved from a retracted state to a deployed state, and to have at least one radius of curvature in the deployed state so that the electrode array forms a series of shaped electrodes in the deployed state.

摘要： Energy delivery systems and methods are provided for use in biological tissue. The energy delivery system includes an energy source and an electrode array. The electrode array includes bipolar electrodes positioned so a first spacing between a pair of adjacent electrodes is different relative to a second spacing between at least one other pair of adjacent electrodes. The electrode array and the energy source are coupled and configured to generate uniform energy density in target tissue according to impedance of the target tissue.
摘要翻译：提供能量输送系统和方法用于生物组织。能量输送系统包括能量源和电极阵列。电极阵列包括双极电极，所述双极电极定位成使得一对相邻电极之间的第一间隔相对于至少一对其它相邻电极之间的第二间隔是不同的。电极阵列和能量源被耦合和配置成根据目标组织的阻抗在目标组织中产生均匀的能量密度。
