The invention relates to a prosthetic foot comprising a main body (10), a proximal connection device (15) for connecting the prosthetic foot (1) to a further prosthesis component, and a foot-front component (12) which is pivotally mounted on the main body (10) and which is associated with a resistance device (20), which resistance device retards plantar flexion of the foot-front component (12), wherein the foot-front component (12) is mounted on the main body (10) via at least one resilient component (30, 31, 32) which moves the foot-front component (12) back into a starting position after a deflection.

A unibody transtibial prosthetic device includes a socket personalized for a specific patient's residual limb. A pylon extends from the socket, the pylon being a unitary polymer structure of interconnected elongated supports having open spaces therebetween. The device also includes a foot-ankle complex, the foot-ankle complex being a unitary polymer extending from the pylon, the foot and ankle unitary structure being shaped to provide multi-axial dynamic flex to enable dorsiflexion, plantar flexion, inversion and eversion motion for smooth symmetric gait performance and energy capture and return. The socket, pylon and foot-ankle complex are portions of a unibody.

An autonomous wearable leg device employs an array of sensors embedded along a support area, whereby a controller can generate a controlling command and send a controlling command to a prosthetic, orthotic, exoskeletal or wearable component to thereby control the prosthetic, orthotic, exoskeletal or wearable component. A method for controlling autonomous wearable device collects kinetic signals from an array of sensors embedded in a prosthetic, orthotic or exoskeletal component, wherein all values are extracted from at least one feature of the collected kinetic signals, which are applied to a controller that generates a controlling command that is sent to the prosthetic, orthotic exoskeletal component to thereby control the prosthetic, orthotic or exoskeletal component during a portion of a gait cycle.

Prosthetic feet that provide for variable and adjustable stiffness are provided. A foot element can include a tongue portion defined or formed by a slot in the foot element that at least partially separates the tongue portion from a remainder of the foot element. The tongue portion can be operably connected to the remainder of the foot member to increase the stiffness of the foot member or operably disconnected from the remainder of the foot member to increase the flexibility of the foot member. The prosthetic foot further includes a mechanism for adjusting whether the tongue portion is operably connected or disconnected from the remainder of the foot member. The mechanism can be selectively actuated to adjust the stiffness of the foot element in dorsiflexion and/or plantarflexion and/or to adjust the degree to which the tongue portion is allowed to flex relative to the remainder of the foot member.

A prosthetic joint can include a first attachment member and a second attachment member coupled to the first attachment member. The second attachment member can include a cylindrical chamber. The prosthetic joint can include a fixation system disposed within the cylindrical chamber comprising at least one cam. The prosthetic joint can have an unlocked configuration, wherein in the unlocked configuration the first attachment member and the second attachment member can rotate relative to each other. The prosthetic joint can have a locked configuration, wherein in the locked configuration the first attachment member is substantially prevented from rotating relative to the second attachment member.

A prosthetic foot can allow a user to engage in different activity levels, for example, walking and running using the same prosthetic foot. The prosthetic foot can have a generally C-shaped upper foot member coupled to a heel member near a toe portion of the prosthetic foot. The heel member can extend from a toe end to a heel end. The prosthetic foot can include a resilient member that can be split into a first component and a second component. The prosthetic foot can include a heel stiffening mechanism with different configurations to adjust a heel stiffness of the prosthetic foot.

Prosthetic feet and foot covers that provide a more natural appearance and improved performance are provided. A foot element for a prosthetic foot can extend from a heel end to a toe end and include a heel, arch, forefoot, and toe regions. The forefoot region can be wider than the arch and heel regions. The toe region can include a U-shaped cut out to define a big toe. Various features of the foot element can guide rollover of the foot through the big toe during use. A foot cover can be designed to receive a prosthetic foot including such a foot element. The foot cover can have a region of increased flexibility at a transition between the forefoot region and toe region. The foot cover can also have a padded area extending from the heel region across a lateral part of the arch region and forefoot region.

The present invention relates to an artificial foot including a foot body part, a toe part rotatably disposed at a first end of the foot body part, a toe joint connecting the foot body part and the toe part to each other, and an adapter disposed on a top of a second end of the foot body part. According to the artificial foot, since the toes of the artificial foot rotate when a wearer walks, when the artificial toes come in contact with the ground, energy is stored due to the load by the weight and the toes kick off the ground as much as the elastic energy accumulated by the spring, so the toe members of the artificial foot do not drag on the ground. Accordingly, the wearer does not need to lift up the hip joints, so the wearer can walk similar to normal walking.

A hollow tubulous composite structure and method for prosthetic limbs is described.
