Abstract: An adjustable socket system includes a distal portion and proximal portion. An axis extends between the distal and proximal portions. A plurality of struts are connected to the distal portion and distributed circumferentially about the axis. The struts at least in part define a receiving volume adapted to receive a residual limb and are movable between an expanded configuration in which at least some of the struts are moved radially outward relative to the axis to loosen the fit of the adjustable system, and a closed configuration in which at least some of the struts are moved radially inward relative to the expanded configuration to tighten the fit of the adjustable socket system. A tightening system is operatively connected to the struts and arranged to differentially tighten and loosen the fit of the adjustable socket system on one or more areas of the residual limb via a single input.

Abstract: An adjustable socket system includes a plurality of shell components and longitudinal supports connected to a base and is movable between an open configuration to loosen the fit of the adjustable socket system, and a closed configuration to secure the fit of the adjustable socket system on residual limb received therein. A tightening system includes a tensioning unit having a handle defining a moment arm rotatable about a rotation axis, and a tensioning element operatively coupled to the handle via a movable connection point and to the shell components via a control point. Rotation of the handle displaces the movable connection point and the tensioning element relative to the control point to move the adjustable socket system to the closed configuration.

Abstract: An adjustable socket system includes a base, longitudinal supports connected to the base and extending along a longitudinal axis, and shell components operatively connected to the longitudinal supports and defining a receiving volume adapted to receive a residual limb. The adjustable socket system is radially expandable between open and closed configurations.

Abstract: A prosthetic attachment system and corresponding lock assembly for connecting a distal end of a prosthetic liner to a distal end of a prosthetic socket. The lock assembly includes a base arranged to be supported by the distal end of the prosthetic socket, and defining a bore. An attachment pin is arranged to be carried by the prosthetic liner and insertable through the bore. A lock mechanism is arranged to be carried by the base and is rotatable about a rotation axis. The lock mechanism includes a control knob extending outwardly from a side of the base. The attachment pin is arranged to interact with the lock mechanism cause the control knob to spin at least one projection of the control knob about the rotation axis.

Abstract: A prosthetic system includes a liner adapted to receive a residual limb and including an outer surface defining an outlet, and a socket including an interior surface and including an aperture extending from the interior surface to an external atmosphere. A first sealed volume is defined between a first portion of the outer surface of the liner and a first portion of the interior surface of the socket. A second sealed volume is defined between a second portion of the outer surface of the liner and a second portion of the interior surface of the socket. The first sealed volume is fluidly connected to the outer of the liner, fluidly separated from the second sealed volume by a seal element, and is independent from the second sealed volume throughout use of the system.
