Abstract: A method of designing and manufacturing an elastic circumferential rim of a prosthetic or orthotic device includes a step of creating a basic structure of the elastic circumferential rim based on the type of the prosthetic or orthotic device. Requirements are determined for stiffness of the elastic circumferential rim in the individual areas along the circumference of the elastic circumferential rim. A structural model of the elastic circumferential rim is created based on the requirements for stiffness of the elastic circumferential rim in the individual areas along the circumference of the elastic circumferential rim and the basic structure of the elastic circumferential rim. The elastic circumferential rim is manufactured based on the structural model of the elastic circumferential rim.

Abstract: An orthotic or prosthetic device with a shaped joint for connecting parts of, in particular, prosthetic sockets, limb orthoses, cranial orthoses, trunk orthoses comprises multiple parts made of different materials. The orthotic or prosthetic device comprises a first part made of a first material and a second part made of a second material connected to the first part. The first material and the second material have different elasticities. The first part and the second part together form a continuous wall of the orthotic or prosthetic device. The first part comprises a groove having a mouth in the wall of the first part. The groove bends around the mouth edge of the groove. The second part comprises a projection following the shape of the groove inserted in the groove.

Abstract: An orthosis (10) for correcting deformities in the head shape of babies and young children includes a mesh layer (20). The mesh layer (30) includes regions of varying stiffness in the mesh layer that are adapted to apply varying pressure to a wearer's head, so as to restrict undesirable growth and allow desired growth to correct the deformities. Accordingly, the mesh layer (30) provides a layer of uniform thickness but variable stiffness, so that a lightweight means of applying appropriate pressure to the wearer's head is provided. The mesh layer (30) can be manufacturer by 3D printing, based on a scan of the wearer's head.
