Abstract
A method of preparing an electrode for use with an implantable medical device, the electrode including a titanium surface, the method including: maintaining a nitrogen gas environment proximate to the titanium surface, delivering energy to a portion of the titanium surface, modifying the portion of the titanium surface with the energy delivered to the titanium surface, and forming titanium nitride by reacting titanium at the portion of the titanium surface with nitrogen from the nitrogen gas environment. Modifying includes increasing a surface area of the portion of the titanium surface, and removing titanium from the portion of the titanium surface. The titanium nitride is formed at the portion of the titanium surface where titanium has been removed.
