Patent ID: 8425505

Claim:
An ablation device, comprising: an elongate member comprising first and second channels; first and second probes disposed within the respective first and second channels, the first and second probes each defining a central axis, the first and second probes each having substantially straight distal ends protruding from the distal ends of the respective first and second channels, the substantially straight distal ends defining an outer surface; and first and second electrodes attached to a portion of the outer surface of the substantially straight distal ends of the respective first and second probes; the first and second electrodes positioned in juxtaposed relationship with the central axis of the first and second probes; wherein a distance between the first and second electrodes is adjustable by rotating at least one of the first and second probes about the respective central axis of the at least one of the first and second probes; wherein the substantially straight distal end of the first probe comprises a sharp distal end and an aperture in communication with a bore formed within the first probe to receive a tissue sample therethrough.
