The present invention relates to a patella protection system (1) comprising an upper member (21) designed to be positioned in proximity of an upper part of the wearer's leg, a lower member (22) designed to be positioned in proximity of a lower part of the wearer's leg and an intermediate guard member (23) designed to be positioned over the patella and operatively connected to the upper member (21) and the lower member (22). The upper member (21) and the lower member (22) are designed to move within the intermediate guard member (23) between a straight configuration and an angulated configuration. The invention also relates to a knee brace (2) comprising such a patella protection system (1).

A positioning device for arranging and orienting multiple securing elements on a base layer of a base body of an orthopaedic device. The positioning device includes a first holder having at least one receiving device for a securing element, and a second holder having at least one receiving device for a securing element, wherein the first holder and the second holder are mounted on one another such that they can swivel about a swivel axis about a restricted angular range starting from a starting position.

A fluidic exoskeleton system. The system can include one or more fluidic actuator units that have: a joint; a first and second arm coupled to the joint; an inflatable bellows actuator extending between a first and second plate associated with the joint, the inflatable bellows actuator defining a bellows cavity, the inflatable bellows actuator configured to extend along a length of the bellows actuator when inflated by introducing fluid into the bellows cavity; and one or more constraint ribs extending from the joint and surrounding portions of the bellows actuator along the length of the bellows actuator.

A strap attachment for attaching a strap to a frame member in an orthopedic device including a retainer; a cable connected to the retainer having at least one segment arranged to be adjustably connected to a frame of a device; a connector securable to an end portion of the at least one segment of the cable, the connector arranged to engage the frame.

A medical ambulatory aid comprising, in combination, a waist belt harness, a thigh brace, a calf brace and a walking boot.

A prosthetic or orthotic device can include at least one device portion and a joint portion for providing for the at least one device portion to pivot between flexion and extension movements relative to another adjacent device portion or an adjacent limb segment of a user. In some embodiments, a prosthetic or orthotic device can include a compliant transmission assembly in operational communication with the joint portion. The compliant transmission assembly can include a compliant member and a pivot. The pivot can be interposed between the compliant member and the joint portion. In some embodiments, the compliant member absorbs energy when a torque is applied.

Disclosed is an electronically adjustable joint, and associated systems and methods. A joint position of a multiple-axis joint, e.g., a 3-axis joint, can be tracked, as the joint moves through two or more dimensions. In an illustrative embodiment, the joint can provide a mechanical equivalent of a physical joint, e.g., a shoulder, elbow, hip, or knee, which can accommodate motion in rotational angle and/or tilt angle. In some embodiments, the joint includes electronically adjustable friction. An illustrative application provides electronically adjustable joints for an aging simulation suit, wherein one or more joints can be controllably stiffened in selective ranges, such that a wearer of the suit can experience the effects of aging, arthritis and/or other ailments. In an illustrative embodiment, a sensor can use four discrete 2-axis magnetometers to calculate the position of the magnet on the arm of the joint, to continuously sense and track the angle of the joint. In some embodiments, the system includes a mechanism, e.g., a servo, which can controllably tighten a socket around a ball joint, wherein the system can controllably adjust friction on the joint.

An orthosis includes a first portion and a second portion configured to attach on opposite sides of a joint. An actuator is configured to apply a force between the first and second portions. The actuator includes a first spool and a second spool rotatably mounted to the first portion. An output pulley is mounted to the second portion. A belt has a first end wrapped around the first spool, a second end wrapped around the second spool, and a mid-portion wrapped around the output pulley. The actuator is configured to rotate the first and second spools. The rotation of the first spool pulls the belt a given length, and the rotation of the second spool feeds the belt less than the given length, so as to pull the output pulley towards the first portion to pull the second portion towards the first portion.

A wearable sitting posture assisting device includes at least one leg unit featuring at least one knee joint and featuring at least one locking unit for the knee joint; includes at least one second leg unit featuring at least one second knee joint and featuring at least one second locking unit; and includes at least one actuation unit featuring at least one manually operable actuation element for mechanically controlling the locking unit and/or the second locking unit.

An orthesis, which has an upper part and a lower part, which are coupled to each other with a first joint device in such a way that the upper part and the lower part can pivot about a pivot axis, wherein devices for receiving a body part or a limb or for fastening the orthesis to a body part or a limb are arranged on the upper part and/or the lower part, and wherein an upper support element is fastened to the upper part on one side and a lower support element is fastened to the lower part on one side, which support elements are connected to each other with a second joint device in such a way that said support elements can pivot about the pivot axis. A bearing plate having at least one fastening device for fastening the second joint device is fastened to or formed on the upper part and/or the lower part.
