摘要：
The invention is a tissue ablation system including an ablation device having an electrode array configured for the ablation of tissue, wherein the electrode array includes a plurality of conductive wires electrically isolated and independent from one another and configured to receive electrical current from a source and emit radiofrequency (RF) energy in response. The ablation system further includes a controller configured to control an emission pattern from the electrode array, either by independently controlling activation of one or more conductive wires or by actively blocking emission of energy from a selected one or more conductive wires or by adjusting flow of a conductive fluid for carrying RF energy emitted in a virtual electrode arrangement. Accordingly, the system provides a user with custom ablation shaping including custom, user-defined ablation geometries or profiles for RF emission in a desired shape or pattern so as to deliver targeted treatment to marginal tissue.
