Patent number: 9681964Abstract: The socket system includes a socket and a vacuum liner. A one-way valve is positioned within the closed distal end of the socket and provides controlled fluid communication between the interior socket space and an external environment. The closed distal end of the vacuum liner includes a distal portion formed of a higher durometer elastomeric material than the surrounding portions of the liner, and including a concave section extending from an external surface thereof towards the interior liner space. The socket, on the interior of the closed distal end thereof, includes a receiving portion that corresponds to and receives the distal portion of the vacuum liner (e.g. matching the perimeter and depth of the distal portion). The receiving portion includes a bottom surface (e.g. a flat surface) opposite to the concave section of the vacuum liner when received therein, and defining an exterior liner space therewith.Type: GrantFiled: December 18, 2014Date of Patent: June 20, 2017Assignee: OSSUR AMERICAS, INC.Inventor: Craig Mackenzie

Patent number: 9675472Abstract: 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.Type: GrantFiled: March 10, 2015Date of Patent: June 13, 2017Assignee: OSSUR AMERICAS, INC.Inventor: Maitland Craig Mackenzie

Patent number: 9345593Abstract: 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.Type: GrantFiled: September 26, 2013Date of Patent: May 24, 2016Assignee: OSSUR AMERICAS, INC.Inventor: Maitland Craig MacKenzie

Patent number: 9168157Abstract: 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.Type: GrantFiled: March 14, 2013Date of Patent: October 27, 2015Assignee: OSSUR AMERICAS, INC.Inventor: Maitland Craig Mackenzie

Patent number: 7833181Abstract: A knee brace has push button actuatable stops, wherein the stops are biased outward into angular locking positions and inwardly directed pressure on the push buttons releases the stops and permits angular adjustment of the stops. A pair of catch plates with locking recesses facing inward, are provided, and outwardly biased locking pins engage the recesses in both catch plates. Each of the stop assemblies has an outwardly directed plate extending over the outer cover plate, and this plate is coupled to the physical stop member around the outer edge of the outer cover plate. The cover plate has angular indicia thereon, which may be viewed through windows in the outwardly extending plate portions of the stop assemblies.Type: GrantFiled: May 13, 2009Date of Patent: November 16, 2010Assignee: Ossur Americas, Inc.Inventors: David Cormier, Tracy Grim, Joseph M.
