Embodiment Construction

[0064] Conventionally, vapor deposition generally refers to a process in which material in a vapor state is condensed to form a solid material. Vapor deposition, generally divided into two broad categories known as physical vapor deposition (PVD) and chemical vapor deposition (CVD), is commonly used to form coatings on objects. Such coatings are provided, for example, to alter the mechanical, electrical, thermal, optical, corrosion-resistant and / or wear-resistant properties of the object.

[0065] As described in detail below, some embodiments of the present invention generally relate to applying a protective barrier layer to an elongated conductive element using vapor deposition. Barrier layers can be applied to conductive elements for a variety of reasons, including providing electrical insulation, biocompatibility, immobilizing microscopic particles, and ensuring passivation of the conductive element, as well as providing isolation of the conductive element from moisture, c...
