Abstract
Tissue ablation probes and methods for treating tissue are provided. The tissue ablation probe comprises an elongated probe shaft, at least one electrode carried by the distal end of the probe shaft, and a pharmaceutical agent carried by the probe shaft. The pharmaceutical agent may be disposed on the electrode(s), the probe shaft, or a releasable portion associated with the electrode or the probe shaft. A method for treating tissue comprises introducing a tissue ablation probe to a tissue site, operating the tissue ablation probe to ablate tissue at the tissue site, and releasing a pharmaceutical agent from the tissue ablation probe at the tissue site.
