Abstract
Delivery elements, including needle electrodes and sheaths of tissue ablation devices, containing a conductivity-enhancing agent are discussed. The delivery elements contain a body member and optionally one or more coating layers. The conductivity-enhancing agent is disposed on or in the body member and/or at least one of the one or more coating layers. The conductivity-enhancing agent is capable of eluting from the delivery element when the delivery element is contacted with bodily tissue or fluid and increases conductivity of the tissue, making tissue ablation more efficient.
