摘要： A method of joining two members of a medical device wherein at least one of the members has a thin layer of joinable material deposited on the surface thereof by vapor deposition, preferably, physical vapor deposition. A guidewire for advancement of intraluminal medical devices may be manufactured by depositing a thin layer of joinable material on the surface of a component which is made from a reactive alloy with a tenacious oxide layer. The thin layer of joinable material facilitates joining difficult to bond materials with other components of the guidewire. Physical vapor deposition may also be used to treat components of medical devices, such as distal guidewire segments, in order to alter their mechanical properties. Specifically, a pseudoelastic alloy segment may be made shapeable by vapor deposition of a non-pseudoelastic metal thereon.
