A prosthetic socket for a residual limb of the lower extremity or upper extremity of an individual person is provided. The residual limb has particular dimensions and anatomical contours; the prosthetic socket has dimensions and contours that fit the dimensions and contours of the residual limb. The prosthetic socket may also fit in a manner that is biomechanically appropriate for the individual. The prosthetic socket may be an assembly from groups of components that include (a) struts arranged longitudinally with respect to the residual limb, (b) proximal brim members arranged proximally to the struts and connected thereto; and (c) distal socket members disposed at the distal base of the prosthetic socket. The socket components within these groups may be modular in that they can vary with respect to dimensions and/or contours, and yet have common connecting features that permit assembly of the components together to form the prosthetic socket.

An outer frame for a prosthetic limb is provided. The outer frame is formed from one or more parts and has a plurality of air flow openings.

Prosthesis devices can include sockets having adjustable features. In one example, a socket includes one or more panels that can move outwardly or inwardly relative to a receptacle portion of the socket. The panels can be moved by tightening a tensioning line.

A prosthetic socket system comprising a prosthetic socket and a liner, said prosthetic socket having a distal end region, at least one socket wall extending therefrom in proximal direction, and connection means for securing a prosthetic component. The socket wall, when in the applied state, at least partially enclose a stump that is received in the prosthetic socket The liner includes a proximal entry opening and a lateral wall which extends in the distal direction, at least partially surrounds a stump when in the applied state and is arranged between the stump and the prosthetic socket when in the applied state. A coupling device is arranged between the liner and the prosthetic socket in the distal end region, and, on the outer side of the lateral wall of the liner and on the inner side of the socket wall, resistance regions are arranged or formed which interact with one another and which counteract a movement extracting said liner out of the prosthetic socket, in the proximal direction.

A prosthesis socket having a proximal insertion opening and an inner circumference which at least partially surrounds a limb stump, at least one connection device for a prosthesis component, which is connectable to the prosthesis socket, at least one actuator operable to change the inner circumference of the prosthesis socket, and at least one sensor coupled to a control device, wherein the control device is connected to the actuator and activates or deactivates same, depending on the received sensor signals, and to a method for adjusting the inner circumference.

An adjustable socket system includes a socket frame having a proximal area, a distal area opposite the proximal area, a first component arranged along a first side of the socket system, and a second component arranged along a second side of the socket system. The first component is connected to the second component. A tubular insert is arranged on an interior of at least the proximal area of the socket frame. The tubular insert forms an interior surface of the socket system. At least one tensioning element operatively connects the tubular insert to the first and/or second components. At least one tensioner is attached to the at least one tensioning element that selectively tensions the tensioning element to adjust a circumference of at least one area of the socket system.

An apparatus for adjusting an expandable prosthetic device includes: an elongated main support having a longitudinal axis and a distal end, and being adapted to connect to an outer or inner side of an adjustable socket having a distal end; an adjustable cup adapted to connect to the distal end of the elongated main support and having an expandable base and at least one side adapted to move laterally toward or laterally away from the longitudinal axis of the elongated main support; and at least a portion of a suspension system disposed in the adjustable cup and having a top adapted to connect to the distal end of the adjustable socket and a bottom adapted to slidably connect to the expandable base of the adjustable cup.

A single socket adjustable prosthetic system having a first shell with an extended surface configured to fit against a first side of an amputee's limb, the surface terminating at a base; a second shell configured to fit against a second side of the amputee's limb; an articulated hinge having a first member, a middle member, and a second member, the first member having a first plate connected to a second plate at an angle to each other, with the second plate hingedly connected to a first end of the middle member and the second member hingedly attached at a second end of the middle member, the first plate removably connected to the base and the second member of the articulated hinge attached to the second shell; a space between the first shell and the second shell, to be varied to hold, and accommodate the amputee's limb.
