The foam insert is for use in manufacturing a prosthetic socket. The foam insert includes an elongated foam body extending from an open end to a closed end, and configured to be positioned within a rigid canister. The elongated foam body includes a contoured exterior surface configured to transfer pressure through to an interior surface thereof to produce consistent surface contact with a residual limb having casting material thereon. The interior surface of the elongated foam body includes a smooth interior surface configured to interface with the residual limb.

The present disclosure provides a device configured to be positioned within a prosthetic socket. The device includes a tether having a first end and a second end opposite the first end. The first end of the tether is configured to be coupled to a prosthetic liner. The device also includes a spool fixed with respect to the prosthetic socket. The second end of the tether is coupled to the spool. The device also includes a motor and a battery configured to provide power to the motor. The device also includes a coupling mechanism configured to transition from a first position in which the spool is only able to rotate in a first direction to a second position in which the spool is able to rotate in the first direction and a second direction. The device also includes a release actuator positioned on an exterior of the prosthetic socket. Actuation of the release actuator causes the coupling mechanism to transition from the first position to the second position. The device also includes a tightening actuator positioned on the exterior of the prosthetic socket. Actuation of the tightening actuator causes the motor to rotate the spool in the first direction to wind the tether around the spool to thereby reduce a distance between the first end of the tether and the spool.

A prosthetic socket system includes a prosthetic lock assembly having a lock body defining a pin hole adapted to receive an attachment pin, and a locking device in the lock body. The locking device is engageable with the attachment pin to unidirectionally lock the attachment pin in the lock body while permitting insertion of the attachment pin in the lock body. A valve assembly is positioned in the lock body that is movable between a closed position and an open position in which the valve assembly is unsealed so that air moves into the lock body via the valve assembly. A release mechanism positioned in the lock body is arranged to both release the locking device from the attachment pin and move the valve assembly to the open position by translating the locking device in the lock body.

A prosthesis device can include a socket or a kit for forming a socket having a lanyard suspension system. In one example, the lanyard suspension system includes a tightening device having a housing, and tightening the lanyard gathers a tensioning line portion of the lanyard into an interior of the housing.

A prosthesis suspension system comprises a socket for receiving a residual limb, a locking liner having a locking pin for attaching the liner to the socket and a sealing cap disposed between the locking line and the socket. The system further comprises a gap between a skirt of the sealing cap and an interior wall of the socket in which the skirt of the sealing cap is able to move between first and second positions.

A vacuum pump may be used to attach a prosthetic and/or orthotic device to a residual limb. The vacuum pump may be in line below a socket of a residual limb. The socket may be a portion of the prosthesis that accepts the residual limb. The vacuum pump may generate a vacuum condition between the prosthesis and the residual limb. Generally, a vacuum condition may be generated between a socket and the residual limb. The residual limb may be covered with a sock, elastomeric liner, or sheath covering the limb. The vacuum condition may positively attach the prosthesis to the residual limb without the need for straps, retaining pins, or suction type vacuum which do not use a vacuum pump.

A suspension interface having a fabric layer with an open proximal end and a closed distal end. The fabric layer can be knit or woven and is preferably made from a stretchable, breathable material such as nylon. At a pre-determined point along the length of the fabric layer, an external sealing element is affixed using conventional gluing means creating a bond layer. The suspension interface has an internal grip layer or external grip layer that is preferably silicone but may also be a thermoplastic material such as urethane. The internal or external grip layer can be as thick as one inch in thickness and as thin as 1/64 of an inch but is preferably about ⅛ of an inch.

A seal component for a prosthetic liner comprises a base portion located at a distal portion of the seal component and anchored circumferentially to an exterior surface of the liner; a seal wall arranged to flexibly and movably extend relative to a body of the liner; at least two seal rings radially and outwardly extending from the seal wall; and an outwardly pitched portion at the distal end of the seal component and extends obliquely away from the base portion relative to the axis of the seal component, and an inwardly pitched portion at the proximal end of the seal component and extends obliquely toward the axis of the seal component, the at least two seal rings are located between the outwardly and inwardly pitched portions.

A prosthetic system includes first and second parts rotatable relative to one another about a joint. The first and second parts are adapted to form at least part of a weight bearing connection between a prosthetic foot and a socket. A pump system includes a pump mechanism operatively connected to the first and second parts. Rotation of the first part and/or the second part about the joint moves the pump mechanism between an original configuration in which the volume of a fluid chamber defined by the pump mechanism is zero or near-zero, and an expanded configuration in which the volume of the fluid chamber is increased.

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.
