An assistive device is disclosed that includes a plurality of control systems for controlling active and passive tasks. The assistive device accommodates active power generation when needed, but is otherwise configured to switch to passive control for other tasks. The assistive device further includes a continuously variable transmission to optimize movement of the assistive device for a variety of tasks. The assistive device includes a lower limb embodiment defining an artificial knee joint controlled by the plurality of control systems.

A method for connecting at least two structural parts of an orthopedic component, wherein the structural parts are retained in an orienting device while oriented in relation to each other, and an intermediate space thus being formed between the structural parts. The orienting device and the structural parts together form a cavity, which has a flow connection to at least one feed connection, via which an adhesive for adhesively bonding the structural parts is introduced into the cavity.

An ankle prosthesis can have a base and an upper hinge component that is pivotably attached to the base about an axis. First and second biasing elements can bias the upper hinge component in first and second rotational directions, respectively. At least one selectively extendable and retractable locking element can extend from one of the base and the upper hinge component and engage the other of the base and the upper hinge component to limit the pivotable movement of the upper hinge component.

A magnetic locking actuator for a prosthetic or orthotic device is provided. The actuator includes a first component including one or more magnets and a second component including one or more magnets. The first and second components are coupled to separate portions of the device. The magnets allow for adjustment of a length of the actuator to adjust an angular orientation of the first and second portions of the device. When magnets in the second component are aligned with magnets in the first component having an opposite polarity, a position of the second component is fixed relative to the first component, locking the actuator. When magnets in the second component are not aligned with magnets in the first component having the opposite polarity, the position of the second component is adjustable relative to the first component, thereby allowing adjustment of the height of the actuator.

A prosthetic foot includes a cap, a retaining element and a plurality of blades. Each of the plurality of blades includes a proximal portion coupled with the cap, a middle portion coupled with the retaining element and a distal portion extending outwardly from the retaining element.

A prosthesis having a prosthetic foot with a forefoot area and a heel area, a prosthetic lower leg, and a prosthetic foot adapter for arranging the prosthetic foot on the prosthetic lower leg. The prosthetic foot adapter includes an upper part for fixing it to the prosthetic lower leg such that it is torque-proof in relation to a sagittal plane, a lower part for fixing it to the prosthetic foot such that it is torque-proof in relation to a sagittal plane, and a resistance element. The upper part can be swivelled on the lower part about a swivel axis against a restoring force exerted by the restoring element, the swivel axis extending from the heel area to the forefoot area.

A prosthetic ankle-foot device, in particular of the biomimetic type, includes: a tibia element; a talus element movably connected to the tibia element through a first talocrural joint having a first hinge joint; a calcaneus element movably connected to the talus element through a second subtalar joint having a second hinge joint; a medial metatarsal element movably connected to the calcaneus element through a third medial midtarsal joint, the third joint having a third hinge joint; a lateral metatarsal element movably connected to the calcaneus element through a fourth lateral midtarsal joint, the fourth joint having a fourth hinge joint; a medial phalanx element movably connected to the medial metatarsal element through a fifth medial metatarsophalangeal joint, the fifth joint having a fifth hinge joint; a lateral phalanx element movably connected to the lateral metatarsal element through a sixth lateral metatarsophalangeal joint, the sixth joint having a sixth hinge joint; an elastic actuation element having an upper part movably connected to the tibia element and a lower part movably connected to the calcaneus element.

A lower limb prosthesis comprises a knee chassis (10), a shin carrier (20) pivotally connected to the knee chassis (10) and a piston and cylinder assembly (30, 40) pivotally connected to the knee chassis (10) and the shin carrier (20). The piston and cylinder assembly (30, 40) comprises a piston assembly (40) comprising a piston (40) mounted on a piston rod (42), a cylinder body (32B) having a cavity (46) defining a cylinder within which the piston (44) is arranged to reciprocate along the piston and cylinder assembly axis, and a foot component attachment means (36) for attaching a foot component to the piston and cylinder assembly (30, 40).

Prosthetic feet that provide improved rollover and performance are provided. A prosthetic foot can include a lower foot member extending from a heel end to a toe end, a second foot member disposed above the lower foot member, and an optional third foot member disposed above the second foot member. The second foot member is tapered such that its thickness decreases toward the proximal end. Optionally, the second foot member can taper toward its distal end as well as toward its proximal end from an intermediate location on the second foot member. The third foot member can be tapered such that its thickness decreases toward the distal end. There can be a gap between a distal end of the third foot member and the second foot member that closes during dorsiflexion of the prosthetic foot during use and provides dynamic stiffness control to the prosthetic foot.

A method for operating an accessory device to guide the placement of an ostomy appliance on a user having a stoma. The method can include capturing an image or a sequence of images of the user applying the ostomy appliance to the user's body, processing the captured image or sequence of images, including: identifying a location of the stoma in one or more of the captured image or sequence of images, identifying a location of the ostomy appliance in one or more of the captured image or sequence of images, and generating location indicia representative of the location of the ostomy appliance with respect to the stoma in one or more of the captured image or sequence of images. A visual display including the location indicia associated with one or more of the captured image or sequence of images can be provided.
