Abstract: The present disclosure provides medical devices and methods of manufacturing medical devices wherein the medical device includes at least one bonding surface that has been roughed by laser etching to increase its surface area and improve its bonding characteristics. In many embodiments, the medical device is an implantable medical device that includes a hermetically sealed metallic housing that is bonded to a prefabricated non-metallic header. The hermetically sealed metallic housing includes at least one surface that has been subjected to a laser etching and roughening process to increase its surface area and improve its bonding characteristics. The laser etched surface may include spots created in a non-overlapping honeycomb-type pattern that may additionally include a series of spikes protruding therefrom to further improve bonding characteristics.
