A continuous socket/suspension monitoring system according to principles of the present invention tracks relative displacement between amputee residuum and their socket using magnetic sensors. The system includes at least one magnetic sensor in a liner worn on the amputees' residuum which correspond to sensors provide in or on the prosthesis socket. The system allows for monitoring of pistoning continuously during locomotion and does not require socket modification, is safe to amputee patients, is easy to use, and is low cost.

A knee prosthesis system including a knee prosthesis, an actuator and a controlling unit. The knee prosthesis includes a thigh segment and a shank segment. The actuator rotatably connects the shank segment and the thigh segment. The actuator is configured to controllably assume a powered knee behavior to generate knee motion or a passive knee behavior to resist knee motion. The controlling unit includes a finite-state control structure. The controlling unit electrically communicates with the actuator. The control structure includes at least three passive states and at least one powered state. The passive states include a passive stance-resistance state, a swing-flexion state, and a swing-extension state and the at least one powered state includes at least one of a swing-assistance state, a stance-assistance state, and a powered-swing state.

Various examples are provided for modular prosthetic devices and their use. In one example, a device includes a chassis assembly including a joint portion; and an interchangeable module that can be removably attached to the chassis assembly. The interchangeable modules can be configured for use in a wide variety of applications. The interchangeable modules can be quickly exchanged for different activities.

A system for attachment of a device to a bone is provided. The system includes an internal axial rod with a proximal and distal end that is configured to be inserted and secured into a bone cavity’s distal end. The system can also include an internal-external transfer rod with a proximal and distal end mounted into the distal end of the axial rod and a central channel extending through the transfer rod from the proximal end to the distal end and a plurality of attachment rings for attaching at least one tissue or muscle group to the transfer rod. The system also includes a bio-compatible and bio-occlusive artificial membranes (BIOCAMS) lamina, wherein the lamina includes either a polyetheretherketone (PEEK) mesh, a biocompatible polymer, a carbon fiber polymer, an artificial tissue polymer, molded donor tissue, allogenic tissue, a collagen/hyaluronic acid-based tissue, or connective tissue biosynthetic substrate material suitable as webbing.

An orthopedic device for the orthotic or prosthetic provision of a patient is provided. The orthopedic device includes a knee joint, which has a proximal upper part and a distal lower part arranged pivotably thereon, an ankle joint, a pivoted foot part which can be fastened distally to the ankle joint, and a shin part arranged between the ankle joint and the knee joint. The upper part of the knee joint or a thigh part fastened thereto that can be attached to the patient's body and is coupled with the foot part by means of a force transfer device, which causes a plantar flexion of the foot part when a knee is flexed.

A suspended sleeve assembly includes a suspension stand and a compression sleeve. An upper portion of the compression sleeve is attached onto the suspension stand, but a lower portion of the compression sleeve is unattached from the suspension stand. The suspended sleeve assembly can also include a support stand. The suspended sleeve assembly can be used to shape a prosthetic socket. The compression sleeve applies a circumferential pressure onto the prosthetic socket as the prosthetic socket is being inserted into the compression sleeve as a patient steps into the compression sleeve and applies at least a portion of body weight to the compression sleeve. The prosthetic socket can be heated and shaped by hand, so that it fits the residual limb of the patient. The suspended sleeve assembly can also be used to shape other prosthetic components, such as a negative plaster cast.
