A prosthetic foot comprising an internal keel (1) and an encapsulation material (2). The keel (1) is made of two parts (3, 4), namely an elastic ankle (3) and an elastic blade (4), to ensure a behaviour of the prosthesis as close as possible to the biomechanics of a sound human foot (plantar flexion, dorsiflexion, inversion, eversion). The materials and design used for the keel (1) allow storing and releasing strain energy at the right phases of the gait cycle. Elastomeric foams act as safety features in specific areas to prevent keel overloading. The keel (1) is preferably encapsulated into two types of foam to fill internal space and as cosmetic feature as it has a human foot shape.

An orthopedic device that includes a foot part, a lower-leg part, and a thigh part. The foot part is connected to the lower-leg part for pivoting about a first pivot axis by an ankle joint. The lower-leg part is connected to the thigh part for pivoting about a second pivot axis by a knee joint. The foot part is connected to the thigh part by a force-transmitting apparatus. The force-transmitting apparatus causes a dorsal flexion of the foot part in the event of a knee flexion over a first knee flexion angle range and causes a plantar flexion of the foot part in the event of further knee flexion after a knee flexion limit angle has been exceeded.

Disclosed herein are devices, systems, and methods for accommodating quick and easy exchange of footwear for lower limb amputees. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

An ankle-foot prosthesis includes a foot plate, an ankle frame attached to the foot plate, a yoke pivotally connected to the ankle frame and including a member for attaching to a leg, a damper having a first end connected to the yoke and a second end connected to the ankle frame, and a control mechanism for switching the damper between low and high settings.

A prosthetic system includes a prosthetic valve having a valve body with a shaft defining a flow channel fluidly connectable to an interior of a socket. One or more ports in the valve body are in fluid communication with the flow channel and a membrane is positioned in the valve body. A release button associated with the membrane controls allow air flow into the socket via the one or more ports while air can flow out of the socket via the one or more ports independent of operation of the release button. A one-way valve is connected to the valve assembly that selectively permit air flow out of the socket. A valve insert is mountable on the socket and arranged to couple the valve body to the socket. The valve insert defines an opening configured to allow the shaft to extend through the valve insert and into the socket.

A movable joint for use in a prosthetic or orthopedic system includes first and second joint sections arranged to rotate relative to one another. At least one shaft member is attached to and arranged to rotate relative to the first or second joint sections. A translating member is attached to the at least one shaft member. Translation of the translating member along a length of the at least one shaft member drives rotation of at least the first joint section and the second joint section.

A device is provided to allow adaptation of a prosthetic or robotic foot in the medial-lateral direction, including pronation and supination of the foot using a series of articulations. Articulations are permitted in the disclosed device due to linkage systems positioned at various locations of the prosthetic foot. In particular, the device includes multiple connected linkage systems each including upper and lower portions with an articulating contact surface designed for load carriage and stability. The point of contact between the contact surfaces of each linkage system comprises the position-dependent instantaneous center of rotation of the upper portion with respect to the lower portion. The device also includes a platform coupled between the linkage systems and a base.

A prosthetic foot (200) that does not require metallic connectors to attach carbon fiber leaf springs (201) and (202) is provided. The carbon fiber leaf springs (201) and (202) are attached together by three-dimensionally stitching prepreg preforms of the carbon fiber leaf springs (201) and (202) at the junction (203) of the carbon fiber leaf springs (201) and (202), and then further curing the stitch attached prepreg preforms. In another embodiment, a woven interlayer attached the two carbon fiber leaf springs (201) and (202).

The invention relates to a method for controlling a prosthetic foot (10) which has an upper part (11) with a fastening element (13) for a proximal prosthetic component (20) and a foot part (12) mounted thereon so as to be pivotable about a pivot axis (15), comprising a resistance device (40) used to counteract a pivoting movement of the foot part (12) relative to the upper part (11) by way of an adjustable resistance (Am), and comprising a control device (70) which is coupled to the resistance device (40) and to at least one sensor (60) and by means of which the resistance to pivoting is set on the basis of sensor data, wherein ground contact of the foot part (12) with the ground is determined by way of at least one sensor (60), wherein the relative spatial position of the foot part (12) and/or of the upper part (11) is determined using an inertial measurement unit (30) and wherein the resistance (Am) to pivoting is altered on the basis of the presence or lack of ground contact and the determined relative spatial position and/or the determined route of the relative spatial position.

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.
