  • Vacuum pump systems for prosthetic limbs and methods of using the same
    Patent number: 9757255
    Abstract: Pump systems for use in suspension of a prosthetic device from a residual limb and methods of suspending a prosthetic device from a residual limb are disclosed. The pump systems include a mechanically activated pump having a first compression member coupled to a second compression member, a compressible bladder disposed between the first and second compression members, and coupling elements that engage and couple together the first and second compression members. The mechanically activated pump may be connected with an electrically activated pump within a fluid circuit of a hybrid pump system to provide vacuum engagement between a prosthetic device and a residual limb.
    Type: Grant
    Filed: June 4, 2015
    Date of Patent: September 12, 2017
    Assignee: Northwestern University
    Inventors: Ryan J. Caldwell, Andrew H. Hansen, Sean M. Wood, Wei Chen, Regan A. Radcliffe, Kevin A. Yngve, Bennett E. Kuhar, Andrew J. Nelson, Eric Nickel
