Abstract: A physiological feature of a subject is monitored by implanting a plurality of targets, such as magnets, and detecting at least one change in a physical property of the targets, followed by modifying a physiological feature of the subject in response to a change of state detected by the change in physical property detected in the targets. Cutaneous sensory feedback and proprioceptive feedback in a subject, as well as selective stimulation of axons or nerve fascicles of a neuron of a subject are provided.

Abstract: Proprioceptive feedback is provided in a residual limb of a person that includes forming a linkage between a pair of agonist and antagonist muscles, forming a sliding surface over which the agonist and antagonist muscles slide. The sliding surface can include a synovial sleeve, a bridge formed between the distal ends of bones, or a fixture that is osseointegrated into the bone. The invention also includes a system for transdermal electrical communication in a person that includes a percutaneous access device, a sensory device that communicates signals between a muscle and the percutaneous device, and a stimulation device in communication with the percutaneous access device. In another embodiment, a closed-loop functional stimulation system restores lost functionality to a person that suffers from impairment of a neurological control system or at least partial loss of a limb.

Abstract: A mechanical interface connecting a biological body segment, such as a limb, portion of a limb or other body segment, to a wearable device such as a prosthetic, orthotic or exoskeletal device, is fabricated by quantitatively mapping a characterized representation of the body segment to form a digital representation of the mechanical interface shape and mechanical interface impedance. The mechanical interface includes a continuous socket defining a contoured inside surface and a contoured outside surface, and includes a material having an intrinsic impedance that varies through the material, so that the intrinsic impedance varies along the contoured inside surface.

Abstract: A link extends between a distal member and a proximal member of a wearable device, such as an exoskeleton, orthosis or prosthesis for a human lower limb. One or other of the distal member and the proximal member includes a crossing member. The link extends from the crossing member of the distal member or the proximal member, to the other of the distal member or the proximal member. Actuation of the link translates to a force at the distal or proximal member that is normal to a major longitudinal axis extending through the distal and proximal members. In one embodiment, a sliding link of a device configured for use with a human joint tracks two degrees of freedom of the joint.

Abstract: Running in a mammal, such as a human, is augmented by adaptively modulating anticipation of maximum leg extension of a mammal when running, and actuating an exoskeletal clutch linked in series to at least one elastic element, wherein the clutch and elastic element form an exoskeleton and are attached in parallel to at least one muscle-tendon unit of a leg of the mammal and span at least one joint of the mammal fitted with the exoskeleton. The exoskeletal clutch is actuated in advance of a predicted maximum extension of the exoskeletal clutch to thereby cause the exoskeletal clutch to lock essentially simultaneously with ground strike by the leg of the mammal. The elastic element is thereby engaged during stance phase of the gait of the mammal while running, and subsequently is disengaged prior to or during the swing phase of the gait of the mammal, thereby augmenting running of the mammal.

Abstract: An artificial foot and ankle joint consists of a curved leaf spring foot member having a heel extremity and a toe extremity, and a flexible elastic ankle member that connects the foot member for rotation at the ankle joint. An actuator motor applies torque to the ankle joint to orient the foot when it is not in contact with the support surface and to store energy in a catapult spring that is released along with the energy stored in the leaf spring to propel the wearer forward. A ribbon clutch prevents the foot member from rotating in one direction beyond a predetermined limit position. A controllable damper is employed to lock the ankle joint or to absorb mechanical energy as needed. The controller and sensing mechanisms control both the actuator motor and the controllable damper at different times during the walking cycle for level walking, stair ascent, and stair descent.
