Abstract: The present invention relates to a knee joint for use in a lower limb prosthesis. The knee joint comprise an upper portion for connecting a custom socket and a proximal attachment, and a support comprising connecting means in its lower part for connecting a prosthetic limb. The support has at least one attachment arm on the medial or the lateral side of the knee joint prosthesis. An actuator is connected between a proximal attachment and the support and is adapted to pivot the upper portion relatively to the support. The actuator comprises a motor directly operatively connected to an axial displaceable shaft capable of changing angular velocity of the knee joint. An external control device can be used to control the knee joint.

Abstract: The invention relates to a prosthetic product having a composite material wall moulded into the shape of a part of a body, characterized in that the wall of the prosthetic product is composed of, on one hand, an reinforcing textile including continuous length fibres, and on the other hand, a textile matrix including thermoplastic polymer fibres, preferably of continuous length.

Abstract: Lock mechanism for detachable connection of a prosthetic device to a sleeve element carried on the residuum of an amputee, comprising a locking pin (3,30,40,50) connected to the sleeve element and a seat (5) arranged on the prosthetic device, in which seat the locking pin is longitudinally inserted for arresting engagement with arresting elements (11,52). The locking pin (3,30,40,50) is flexible for bending at least in one plane coincident with the longitudinal axis of the locking pin, and is preferably also longitudinally elastic.

Abstract: A soft and elastic prosthetic liner blank for customizing to an individual user is formed from thermoplastic material and molded to a hollow, generally rotation symmetric shape having at least one radial dimension. The liner blank has an open proximal end for insertion of the residuum of an amputee's arm or leg and a closed distal end, and the liner blank further having a material composition allowing thermo-forming of the liner blank while maintaining elasticity in the thermally applied shape. The radius of the liner blank is dimensioned to accommodate and to adopt, through plastic deformation, any sectional profile included in the positive copy.

Abstract: A method for creating a flexible sleeve member for an amputation stump. The sleeve member is made of a thermoplastic elastic and transparent material. The sleeve member is shaped after a flexed limb, for instance a knee, which makes it easier to avoid foldings of the sleeve, which would otherwise be obtained at the back of the knee when a person wearing the prosthetic device sits down. By means of the sleeve member according to the invention, comfort is improved for a person wearing such a prosthetic device.
