1. A method of delivering an electric field to a target tissue, comprising:
- advancing an ablation probe into a patient;
deploying a guide from the delivery member along a guide tissue penetration path, the guide path curving in a first direction;
deploying an electrode from the guide along an electrode tissue penetration path, the electrode path curving in a second direction; and
establishing current flow extending within the target tissue using the deployed electrode.

12. A method of delivering an electric field to a target tissue, comprising:
-
positioning an ablation probe in a tissue of a patient; deploying a plurality of electrodes from the probe to define an ablation volume, wherein deploying an electrode of the plurality comprises deploying a microtube from a delivery member of the probe in a first direction and deploying in a second direction an electrode from a lumen of the microtube; establishing current flow through the ablation volume to provide one or more electric fields extending through the volume.
