摘要： 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.

摘要： 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. The shell components include a first shell component having distal and proximal parts that are longitudinally displaceable with respect to one another such that a length of the first shell component is adjustable between a first length and a second length different than the first length.

摘要： A method for making a prosthetic liner includes the steps of providing a textile sleeve, applying an uncured silicone material onto an inner surface of the textile sleeve and impregnating interstices of a high-density knit structure of the textile sleeve. The silicone material is a fast-cure silicone material arranged to reach at least 90% cross-linking faster than conventional silicone material. The silicone material is preferably limited to the inner surface of the textile sleeve, whereas the outer surface is devoid of the silicone material. The silicone defines an inner layer forming the interior surface of the liner, and the outer surface of the textile sleeve forms the exterior surface of the liner. A thickness of the liner from the interior surface of the liner to the inner surface of textile layer consists of the silicone of the inner layer.

摘要： A prosthetic attachment system includes an insert arranged for connection to a prosthetic liner, and an attachment unit arranged for connection to a distal end of a prosthetic socket. The attachment unit comprises a body defining an axis and a central opening for selectively receiving the insert. The body carries a plurality of locking elements that are distributed circumferentially about the axis and radially repositionable relative to the axis. A release mechanism is slidably positioned on an outer surface of the body to move the prosthetic attachment system between a locked configuration in which the locking elements are radially repositioned to lock the insert in the central opening of the body and an unlocked configuration in which the insert is released from the central opening.

摘要： A prosthetic liner includes a textile cover having at least first and second regions having different elongation from one another. The first region is in a prestretched configuration in at least one orientation relative to an axis of the prosthetic liner and locked in the prestretched configuration according to a layer of elastomeric material located along a surface of the textile cover.

摘要： A prosthetic interface includes a body portion having an open proximal end and a closed distal end including a distal cup. The body portion includes a membrane component having a flexible configuration defining an internal flow space extending along a length of the membrane component between an inner side arranged to face a skin surface of a residual limb and an outer side arranged to face away from the skin surface. At least one material coating is selectively applied to the membrane component that interacts with at least one of the membrane component and the distal cup to define at least one breathable region along the inner side that allows fluid flow between the internal flow space and the residual limb, and at least one impermeable region along the outer side that allows for vacuum suspension between the prosthetic interface and a prosthetic socket.
