Abstract
A method is disclosed for rapidly removing electrically insulative coating material from a portion of the titanium housing of an implantable cardiac pulse generator. Pulsed excimer laser radiation ablates an organic coating, such as parylene or a similar polymer, to micromachine a conductive window having sharply defined boundaries or edges. An implantable cardiac pulse generator having an electrically conductive window produced according to the method is also disclosed. The method is suitable for high volume automated production of face or edge window pulse generators, and is also applicable for removal of biomolecular films from other medical articles.
