Provided is a resin-impregnated rolled fabric sock with one or more opposed pairs of tails for ease of applying the sock to the limb, the sock being useful for preparing casts or forms on limbs. The sock is provided rolled upon itself down the outer side from the open end to the closed end and along the long axis of the sock. The tails are incorporated into the roll, however an exposed end of each tail remains external to the roll. In an embodiment, the resin-impregnated, rolled sock is provided in a sealed moisture impermeable container. Also provided are methods of use.

A medical apparatus is provided for use in manufacturing a plaster impression of limb stump, in particular of a lower stump, wherein the apparatus comprises a pressure vessel with a fluid container of pressure chamber for receiving or storing a fluid being under pressure, wherein the pressure vessel comprises a wall made of a first material, wherein the wall limits the an interior of of the pressure vessel against an exterior, wherein the pressure vessel comprises an insertion opening for the insertion of a limb stump into the interior of the pressure vessel and a fluid-tight membrane made of a second materials, which is arranged to form or limit the fluid container or the pressure chamber. An upper section of the membrane is preferably releasably fastened at or to the pressure vessel by a connector.

An adjustable socket system, method, and kit for use with prosthetic devices or orthotic, orthopedic, or exoskeletal support devices that includes a paddle and a compressing device coupled to the paddle. The paddle is chosen from a plurality of paddles of different shapes in such a way that the paddle inner surface is substantially coextensive with a soft tissue area overlying skeletal structures. The compressing device presses the paddle against the soft tissue area in order to minimize the motion of the paddle relative to the underlying skeletal structures without causing discomfort to the user or compressing areas not in contact with the paddle, allowing compressed tissue to flow into uncompressed areas. The system, method, and kit can include an external tool, sensors, actuators, and controllers, to assist fitting and for adjustment after fitting. A stabilizer can be added to resist the bending force on the paddle.

A method for making a mould of an amputation stump, in which the amputation stump is inserted into a liner of a moulding aid, the liner having a longitudinal direction and a circumference, and the liner having an expansion coupling such that when the liner is extended in the longitudinal direction, this necessarily results in a reduction of the circumference.

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.

A flexible inner socket is fabricated by forming a pre-socket. The pre-socket includes a body formed with an opening and an enclosed end. The enclosed end is opposite to the opening. The body of the pre-socket has an outer circumference that is smaller than the inner circumference of the rigid prosthetic socket. Different portions of the body may have different thicknesses. The preform socket is heated. After the heating, the flexible inner socket is formed by molding the pre-socket onto the inner surface of the rigid prosthetic socket to form the flexible inner socket. The inner circumference of the rigid prosthetic socket is reduced by a thickness of the flexible inner socket when the flexible inner socket is attached to the inner surface of the rigid prosthetic socket. An opening of the flexible inner socket may be trimmed after the formation to fit contours of an opening of the rigid prosthetic socket.

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.

A method of engaging a limb with an interface using an external tool is described. The method includes the steps of: (i) removably attaching one or more actuators of the external tool to one or more paddles of the interface; (ii) operating the actuators to adjust a position of the paddles inward or outward relative to a longitudinal axis of the interface; and (iii) selecting a compression force for each of the paddles so as to compress target areas of soft tissue in the limb against skeletal structure to reduce motion of the skeletal structure towards an inner surface of the paddles.

The present invention relates to a medical apparatus (100) for use in manufacturing a plaster impression of limb stump, in particular of a lower stump, wherein the apparatus (100) comprises a pressure vessel (1) with a fluid chamber of pressure chamber (DK) for receiving or storing a fluid (F) being under pressure, wherein the pressure vessel (1) is limited against an exterior (), wherein the pressure vessel (1) comprises an insertion opening (9) for the insertion of a limb stump (KS) into the interior (I) of the pressure vessel (1) and a fluid-tight membrane (5) made of two materials, which are arranged to form or limit the fluid chamber or the pressure chamber (DK). In addition, the present invention relates to a system (300) having a medical apparatus (100) and at least one contact surface (111). Furthermore, the present invention relates to a method.
