Abstract
An electrosurgical instrument includes a support member and an electrode. The electrode is disposed on the support member and has a coating disposed thereon. The coating includes a seed layer and an atomic-layer-deposition (“ALD”) layer. The ALD layer is hydrophobic or hydrophilic. The seed layer may be conductive or insulative.
