  • Systems and methods of loading fluid in a prosthetic knee
    Patent number: 7198071
    Abstract: The invention in some embodiments relates to systems and methods of loading fluid in a prosthetic knee. A vacuum fill technique is utilized in one embodiment to load magnetorheological fluid within small gaps in a chamber of a prosthetic knee. Advantageously, this allows for an efficient loading scheme thereby desirably allowing for faster manufacturing speed. Another advantage is that the magnetorheological fluid is substantially uniformly distributed within the small gaps thereby desirably providing consistent production.
