A prosthetic liner having a lower longitudinal stretch in the distal region than in either the proximal or optional intermediate region. The distal region may stretch anywhere from 0-30% vertically and 10-200% horizontally as compared to the proximal region's vertical stretch of 55-125% and 100-175% horizontally. The stretch of the liner at various pressure sensitive regions of a residual limb can also be lowered or heightened depending on the area. A variety of stitches may be used at the distal end to implement this lowered longitudinal stretch. Preferably, the liner is made of a stretchable material. The liner also has an interior layer of elastomer gel. The design of this prosthetic liner is primarily to prevent the “pistoning” of the amputee's residual limb within the liner and for comfort over pressure-sensitive areas of the residual limb. The liner also includes the use of a low extensibility material which is adhered to the fabric portion of a prosthetic liner or orthotic liner either internally or externally and limits the longitudinal movement while allowing for transversal movement. The customizable nature of the invention allows for shaping and personalization depending on the needs of the user.

A medical apparatus for use in generating a data model of a limb stump is provided, wherein the apparatus includes at least a pressure vessel with a fluid chamber or a pressure chamber for receiving or storing a fluid, wherein the pressure vessel includes a wall made of a first material, wherein the wall limits an interior of the pressure vessel against an exterior, and wherein the pressure vessel includes an insertion opening for inserting the limb stump into the interior of the pressure vessel. The apparatus further includes a fluid-impermeable membrane made of a second material and arranged to form or limit the fluid chamber or the pressure chamber. Furthermore, the apparatus comprises an adherent stocking or another sensor arrangement, to be pulled over the limb stump, wherein the adherent stocking includes sensors for generating the data model.

An artificial limb. The artificial includes a finger part and a drive unit for the finger part. The drive unit includes: a drive output part, a movable part and a drive rope. The movable part is configured to be connected with the drive output part and is capable of moving under a drive of the drive output part. The drive rope is configured to be disposed in the finger part and connected with the movable part and is capable of converting a movement of the movable part into a motion of the finger part.

A method for producing an orthopedic device, wherein the method comprises: providing a main body of the orthopedic device that comprises at least one volume that can be filled with a fluid, at least one supply line to this volume, and a flexible and/or elastic material in at least some sections of the main body in which there is no volume that can be filled with a fluid, arranging the main body on a body part of a patient, at least partially filling the volume with a curable fluid, and curing the curable fluid.

A prosthetic socket includes a conical cup, an outer layer on the outer surface of the conical cup, and a reinforcement layer on the inner surface of the conical cup. The prosthetic socket is shapeable after being heated to a shaping temperature. The outer layer is less malleable than the conical cup at the shaping temperature, but has a higher rigidity than the conical cup at the shaping temperature and has smoother outer surface than an outer surface of the conical cup. The reinforcement layer has a higher resistance against circumferential stress than the conical cup. A residual limb or a model of a residual limb can be inserted into the preformed prosthetic socket. The prosthetic socket is then heated to the shaping temperature and molded to conform to the contour of the residual limb or the model to form a prosthetic socket.

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.

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.
