A prosthetic foot can have an ankle unit with semi-active adjustable stiffness. In one example, the adjustable stiffness is in the sagittal plane. The ankle stiffness can be varied by the ankle unit in response a user input, which can be received via a wireless communication device. The ankle unit can include two load application locations for one or more cantilever springs so as to provide different stiffness in plantarflexion and dorsiflexion. The positions of the two load application locations can be varied in order to vary the stiffness.

Prosthetic foot with variable stiffness ankle

A prosthetic foot comprises an attachment member and two or more flexible members. The attachment member can include a connector configured to connect the attachment member to a user or another prosthetic device. The two or more flexible members can be rotatably attached to the attachment member by rotatable joints such that the flexible members can both rotate and flex relative to the attachment member when the prosthetic foot contacts the ground.

Prosthetic foot with enhanced stability and elastic energy return

A prosthetic foot including a continuous body extending from a proximal end to a distal end. The body includes an anterior surface, a posterior surface opposite the anterior surface, and a fin on the posterior surface. A prosthetic foot can include a first footplate and a second footplate. The first footplate extends between a proximal portion and a distal portion. The proximal and distal portions of the first footplate are configured to operatively engage a support surface during ambulation. The second footplate extends between a proximal portion and a distal portion. The distal portion of the second footplate is coupled to the first footplate at an intermediate location between the proximal and distal portions of the first footplate. The second footplate incudes an anterior surface, a posterior surface opposite the anterior surface, and a fin on the posterior surface.

Prosthetic foot with layers of fibrous material

A structure assembled by first and second stackable layers having properties allowing for the first and second stackable layers to be shaped into at least first and second different shapes, and at least one fastener to releasably secure the first and second stackable layers together in one of the at least first and second shapes in a semi-rigid or rigid, and unitary construction. The first and second stackable layers are secured into one of the at least first and second shapes by the at least one fastener to form a semi-rigid or rigid, and unitary construction.

Structure comprising stackable layers

A traction system for an ambulatory support such as a prosthetic foot blade or a crutch includes a sole plate, a latch assembly, and a strap. The sole plate is couplable to a distal end of the ambulatory support to extend under a bottom side of the ambulatory support and a latch assembly. The latch assembly includes a front catch and a rear catch both fixable at a top side of the ambulatory support with the front catch nearer to the distal end of the ambulatory support than the rear catch, and a lever having a front end and a rear end, the front end releasably latchable to the front catch and the rear end releasably latchable to the rear catch when the lever is pivoted about the latched front end. The strap is secured to the lever and to the sole plate.

Traction system for an ambulatory support

A vertical suspension system for a prosthetic foot includes a first member operatively coupleable to an amputee's residual leg. The suspension system can also include a second member coupleable to a prosthetic foot. One or more upper leaf springs and one or more lower leaf springs extend between and are attached to the first and second members such that at least one of the ends of each leaf spring is rotationally fixed to the first or second members, where the upper an lower leaf springs are spaced apart from each other.

Frictionless vertical suspension mechanism for prosthetic feet

A prosthetic foot can include an attachment member, at least one first brace, at least one first flexible member, an unpowered actuator, at least one second brace, and at least one second flexible member. The attachment member can include a connector configured to connect the attachment member to a user or another prosthetic device. The at least one first brace can mount to the attachment member and the at least one first flexible member can connect to the attachment member by the at least one first brace such that a force between the ground and the attachment member can be supported by the at least one first flexible member. The unpowered actuator can mount to the attachment member and the at least one second brace can mounted to the actuator. The at least one second flexible member can connect to the attachment member by the at least one second brace such that a force between the ground and the attachment member can be supported by the at least one second flexible member.

Prosthetic foot with removable flexible members

A variable stiffness spring assembly includes first and second members made of a first material and separated by a gap along at least a portion of their lengths, and one or more layers made of a second material disposed in the gap. The variable stiffness spring assembly can be incorporated into or take the form of a limb support assembly, such as a prosthetic foot. The second material disposed between the first and second members is rate-sensitive or speed-dependent, such that the material exhibits different properties when the user of the prosthetic foot is walking at high or fast walking speeds compared to low or slow walking speeds. The prosthetic foot can exhibit high damping and energy absorption, and therefore stability, at slow speeds, and high energy return at faster speeds.

Variable stiffness mechanisms

A limb support device includes a variable stiffness mechanism. The limb support device can be an orthotic or prosthetic device. The variable stiffness mechanism can include, for example, a rate-sensitive or speed-dependent material or a damping mechanism. The variable stiffness mechanism causes the limb support device to exhibit different properties when the user of the limb support device is walking at high or fast walking speeds compared to low or slow walking speeds. The limb support device can exhibit high damping and energy absorption, and therefore stability, at slow speeds, and high energy return at faster speeds.

Variable stiffness mechanism and limb support device incorporating the same

An attachment for a prosthetic foot comprising an attachment surface that couples to the edges of a foot plate of a prosthetic foot and an outer surface that functionally or cosmetically alters the foot plate of the prosthetic foot in order to adapt the prosthetic foot to the needs of the user. In another embodiment, a toe attachment for a prosthetic foot comprising a cavity that can receive the toe end of an elongate foot element of a prosthetic foot, the toe attachment that can functionally or cosmetically alter the elongate foot element in order to adapt the prosthetic foot to the needs of the user. In yet another embodiment, a seal cover that can removably engage a prosthetic foot and a cosmetic cover for a prosthetic foot, resulting in a substantially watertight connection between the seal cover and the prosthesis and the seal cover and the cosmesis.

Overmould attachments for prosthetic foot

Prosthetic foot

A prosthetic foot can include an attachment member, at least one first brace, at least one first flexible member, an unpowered actuator, at least one second brace, and at least one second flexible member. The attachment member can include a connector configured to connect the attachment member to a user or another prosthetic device. The at least one first brace can mount to the attachment member and the at least one first flexible member can connect to the attachment member by the at least one first brace such that a force between the ground and the attachment member can be supported by the at least one first flexible member. The unpowered actuator can mount to the attachment member and the at least one second brace can be mounted to the actuator. The at least one second flexible member can connect to the attachment member by the at least one second brace such that a force between the ground and the attachment member can be supported by the at least one second flexible member.
