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.

An intra-frame positioning sling may be disposed internally within a prosthetic socket frame. The sling may include one or more proximal suspension portions adapted to suspend from a proximal aspect of the frame and a tensioning system. The sling may include a first longitudinal side with one or more proximal suspension portions and an opposite longitudinal side that includes the residual limb interfacing or force application portion of the sling. When the tensioning system is tensioned, the sling is pulled toward the first longitudinal side of the prosthetic socket frame. A set of two positioning slings may be rigged in a transfemoral prosthetic socket frame; one sling applies force on a medial side of a hosted residual limb, and the other sling applies force on the lateral side.

A transtibial prosthetic socket frame may include a distal base assembly having a base plate, a carriage configured to support a socket suspension arrangement, and a distal prosthetic component connector. The distal base assembly supports a set of struts that includes two anterior struts and a single posterior strut. The set of struts and distal base assembly collectively define a prosthetic socket cavity having a central longitudinal axis and a residual limb hosting volume. The distal prosthetic component connector has a connecting adapter that is rotatable with respect to the prosthetic socket, and moveable with respect to the base plate between being aligned with the prosthetic socket's central longitudinal axis and a position offset therefrom.

The invention relates to a method for producing an adapted liner for placement on a stump (1), particularly an amputation stump, comprising the following steps: selecting a prefabricated liner (3) as a function of the size of the stump; applying a filling compound (2) onto regions of the stump (1) that deviate from the inside contour of the prefabricated liner; and connecting the filling compound (2) to the prefabricated liner (3).

Adjustment and metrology systems include a first securing component configured to hold a first region of the medical device. A second securing component is configured to hold a second region of the medical device, the first securing component and the second securing component being spaced apart in a Z-direction. A plurality of positioning mechanisms is coupled to at least one of the first securing component or the second securing component, the plurality of positioning mechanisms being configured to provide a combined total of at least six degrees of freedom between the first securing component and the second securing component, wherein the degrees of freedom comprise translational movement in an X-direction, a Y-direction, and the Z-direction and rotational movement about an X-axis, a Y-axis, and a Z-axis. A heater is positioned between the first securing component and the second securing component.

The present disclosure is directed to prosthetic limb sockets that couple prosthetic limbs to residual limbs. The sockets include a conical cup sized to engage and couple to the residual limb, and a base to secure the socket to the prosthetic limb. The sockets are direct heat-formable onto the residual limb, such that they can be heated and formed as they are secured to the residual limb.
