Abstract
Orthotic and prosthetic devices having integrated features such as cushioning features are described, as well as methods for computer aided designing and making of these devices. The orthotic or prosthetic devices comprise a cushioning layer superimposed onto an orthotic or prosthetic shell, the cushioning layer comprising an array (35) of discrete solid and resilient cushioning elements (31). In one preferred embodiment, the cushioning structure is a beam, defined around a centerline of any arbitrary shape. In another preferred embodiment, the cushioning structure has the shape of a spiral.

An orthotic or prosthetic device comprising:
- a plurality of orthotic or prosthetic shells and a plurality of cushioning layers forming a sandwich structure,
- the plurality of cushioning layers comprising an array of discrete solid, deformable, and compressibly resilient cushioning elements that are homogenously formed with the plurality of orthotic or prosthetic shells, wherein one or more of the cushioning elements of the array comprises a beam that is wider in a first direction than in a second direction and comprises a first side and a second side opposite the first side, wherein the first side is superimposed onto a first shell of the plurality of orthotic or prosthetic shells and wherein the second side is superimposed onto a second shell of the plurality of orthotic or prosthetic shells that is different from the first shell.
A device configured to be worn by a user, comprising:
- a body arranged to spread pressure between a body part of the user and the device;
- and
- a plurality of orthotic or prosthetic shells and a plurality of cushioning layers forming a sandwich structure, the plurality of cushioning layers comprising an array of discrete solid, deformable, and compressibly resilient cushioning elements homogenously formed with the body, wherein one or more of said cushioning elements of the array comprises a beam that is wider in a first direction than in a second direction and comprises a first side and a second side opposite the first side, wherein the first side is superimposed onto a first shell of the plurality of orthotic or prosthetic shells and wherein the second side is superimposed onto a second shell of the plurality of orthotic or prosthetic shells that is different from the first shell.
