A method of providing a modular prosthetic socket for a residual limb of a patient may involve receiving digital data defining a three-dimensional digital profile of the residual limb and selecting prosthetic socket components from component-specific inventories, based at least in part on the digital profile. The selected prosthetic socket components may include: multiple longitudinal struts; one or more proximal brim members for attachment to the longitudinal struts; and a distal socket base to which the longitudinal struts attach at or near their distal ends. The method may further involve providing the selected prosthetic components to an operator for assembling into the modular prosthetic socket. The prosthetic socket, when assembled, defines an internal space substantially complementary to the profile of the residual limb.

The invention is a method of designing and manufacturing a 3D printed prosthetic socket or a standard prosthetic socket with a 3D printed distal end, comprising a step of obtaining physical data about a patient with a residual limb and a step of creating a structural design of the 3D printed prosthetic socket or standard prosthetic socket with the 3D printed distal end. The step of creating the structural design of the 3D printed prosthetic socket (3) or standard prosthetic socket with the 3D printed distal end comprises a step of determining the bulk density of the structure of the prosthetic socket between a shaped area for positioning a linking part of the liner and a distal planar area for mounting a linking adapter of the socket directly proportional to at least one of the data from a set including at least weight, patient's degree of activity, length of the residual limb, length of the prosthesis, size of the prosthetic foot, and angle between the axis of the limb and the axis of the prosthesis.

A transfemoral prosthetic level socket system for a user's lower limb comprising modular socket components fitted to the individual user's residual limb having a mounting point for an attachment, at least one compliant member attached to at least one stabilizing unit, and at least one second compliant member attached to at least one stabilizing unit wherein the first compliant member and the second compliant member work in cooperation with the stabilizing unit(s) to control bone position and support the limb within the interface.

Methods and systems for cushioning a residual limb in a prosthetic generally comprise prosthetic limb devices, sockets, bladders, and valve stems. In a preferred embodiment, the residual limb/stump is configured and arranged within the socket and rests on the bladder. The valve stem coupled to the bladder is configured and arranged through the bottom of the socket to allow quick and easy inflation of the bladder. In some embodiments, the present invention also includes upper thigh attachments which may include ball bearings, axles, and thigh straps. In another preferred embodiment, the upper thigh attachment allows the user to securely and adjustably attach the prosthetic limb device to the user's upper thigh.

A structure assembled by first and second stackable layers having properties allowing for the first and second stackable layers to be shaped into at least first and second different shapes, and at least one fastener to releasably secure the first and second stackable layers together in one of the at least first and second shapes in a semi-rigid or rigid, and unitary construction. The first and second stackable layers are secured into one of the at least first and second shapes by the at least one fastener to form a semi-rigid or rigid, and unitary construction.

A prosthesis device having a tension element fastened to a tensile force brace, which drives a movable component of a prosthesis device upon applying a tension force, wherein a sensor device is allocated to the tension element which detects the actuation of the tension element and activates a motor allocated to the movable component.

An adjustable socket system includes first and second shell components and first and second longitudinal supports connected to a base. The socket system is movable between an open configuration to loosen the fit of the socket system, and a closed configuration to secure the fit of the 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 located and protected between the first shell component and the first support 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 socket system to the closed configuration.

A prosthetic connector system for use with a prosthetic socket having a distal end includes a plate defining a plurality of holes and attachable to the distal end of the prosthetic socket. A component is removably attachable to the plate via the plurality of holes and arranged to connect a prosthesis to the prosthetic socket. The plate defines an outer periphery having an asymmetrical configuration contoured to substantially correspond to at least a portion of the component when the component is attached to the plate via at least some of the holes.

An adjustable prosthetic device and a fitting tool for positing the prosthetic device on a limb are described. The prosthetic device comprises two or more adjustable paddles that are movably coupled with an adapter via connectors. The connectors allow the paddles to be repositioned relative to a user's limb. The paddles are sized and dimensioned to capture lost motion between the limb and the prosthetic device through skeletal compression and tissue displacement. The fitting tool comprises two or more compression bars that removably couple with the two or more paddles of the prosthetic device. The fitting tool also comprises two or more linear actuators that control the positions of the compression bars and the paddles relative to the limb.
