  • Patent number: 9788977
    Abstract: A suspension liner for a residual limb has a liner body with a plurality of anterior and posterior projections formed from a thickness of the liner body. Medial and lateral tendons are located between and correspond to profiles of the plurality of the anterior and posterior projections such that the medial and lateral tendons are located on opposed sides of the liner body relative to one another. The medial and lateral tendons flare circumferentially toward proximal and distal sections of the liner body.

  • Patent number: 9675472
    Abstract: A mounting plate system for use with a prosthetic socket includes a mounting plate having a cylindrical configuration. The mounting plate includes a top face arranged to be adjacent to a distal outer periphery of the prosthetic socket and a bottom face for attachment to a prosthetic limb. An opening extends from the top face to the bottom face. A bottom recess has a cylindrical configuration and extends from the bottom face and surrounds the opening. A top recess has a cylindrical configuration and extends from the top face and surrounds the opening.

  • Patent number: 9345593
    Abstract: The mounting plate system is for use with a prosthetic socket, the socket having at least one aperture in a distal end thereof and in fluid communication with an interior portion of the socket which receives a residual limb. The mounting plate system includes a mounting plate having a top face to interface with the socket, and a bottom face for attachment to lower portions of a prosthetic limb. An opening in the mounting plate extends from the top face to the bottom face thereof, and a valve housing is positioned in the opening and has a channel therein for fluid communication with the interior portion of the socket via the at least one aperture. A one-way expulsion valve is secured between the valve housing and the socket adjacent the aperture and for regulating fluid communication between the interior portion of the socket and the channel in the valve housing. A vacuum reservoir seal plate is also provided.

  • Patent number: 9259333
    Abstract: A prosthetic device and a method for making the same includes a mounting plate assembly. The mounting plate assembly includes an inner housing having a first center channel defined along a central axis, an outer housing having a second center channel defined along the central axis, and a fluid regulator arranged between the inner and outer housings, and defined along the central axis. The prosthetic device includes a socket having a cavity and a distal portion whereat the mounting plate assembly is located.

  • Patent number: 9168157
    Abstract: The sealing sheath is for use with a prosthetic socket and associated liner. The sealing sheath includes a textile tube for surrounding at least a portion of a liner that is configured to wear on a residual limb. An annular seal, e.g. an elastomeric or silicone seal, is positioned adjacent a proximal end of the textile tube and continuously extends from an inside of the textile tube configured to be adjacent the liner, through the textile tube to an outside thereof configured to be adjacent an inside of the prosthetic socket. The annular seal may include a first wing on an inside of the textile tube configured to be adjacent the liner, a second wing on an outside of the textile tube configured to be adjacent an inside of the prosthetic socket, and a base connecting lower ends of the first and second wings to define a v-shaped cross-section of the annular seal.

  • Publication number: 20150238329
    Abstract: A suspension liner for a residual limb has a liner body with a plurality of anterior and posterior projections formed from a thickness of the liner body. Medial and lateral tendons are located between and correspond to profiles of the plurality of the anterior and posterior projections such that the medial and lateral tendons are located on opposed sides of the liner body relative to one another. The medial and lateral tendons flare circumferentially toward proximal and distal sections of the liner body.
