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.

Prosthetic foot with removable flexible members

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

Various features for improving the performance of crutches are provided. A crutch can flex at one or more locations or include composite material to provide energy storage and return to the user during ambulation. In some aspects, a crutch is provided that can propel the user forward during ambulation. The crutch can be hollow at one or more locations to allow for increased flexibility and narrower at one or more locations to enhance springiness of the crutch.

Crutch with energy storage and energy return

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.

Magnetic locking mechanism for prosthetic or orthotic joints

Prosthetic devices and methods of controlling the same are provided. A prosthetic ankle device includes a foot unit and lower limb member moveable relative to one another and defining an ankle angle therebetween. The prosthetic ankle device further includes a controller to operate the device based on detecting a decreased load. Methods of controlling the prosthetic ankle device include operating the device at different ankle angles depending on detecting a decreased load on the prosthetic ankle device while standing or stopped.

Prosthetic ankle and method of controlling same based on decreased loads

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 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.

Prosthetic feet and foot covers

A powered prosthetic thigh can have a proximal portion configured to couple to a prosthetic hip socket and can have a distal portion attached to the proximal portion. The distal portion can have a distal connector configured to couple to a prosthetic knee. The powered prosthetic thigh can also have a computer controlled actuator configured to rotate the prosthetic thigh relative to the prosthetic hip socket.
