Abstract:
1. A method of bonding one component of a medical device to another component of the medical device, the method comprising: positioning a first component in close proximity to a second component to form an assembled configuration, at least one of the first and second components comprising a shape memory material; heat treating the assembled configuration at a temperature in the range of from about 800° C. to about 1100° C. to form a diffusion bond between the first component and the second component at a region of contact between the components; forming the assembled configuration into a desired set shape; and heat setting the assembled configuration at a temperature in the range of from about 350° C. to about 550° C. to impart a memory of the desired set shape to the shape memory material without substantially impairing the diffusion bond between the components, wherein the heat treating is carried out for a duration in the range of from about 15 minutes to about 60 minutes and the heat setting is conducted for a duration in the range of from about 10 minutes to about 30 minutes.
