The present invention relates to a prosthesis covering (100) with a closed cross-section which comprises a first section (10), a second section (20) and a third section (30). The second section (20) is arranged in longitudinal direction between the first section (10) and the third section (20) an consists of other material than the other two sections. The second section (20) may optionally at least in a first subsection (21) be folded, doubled over, raised, lamella-like or multi-layer.

A prosthetic foot cover for a prosthetic foot having a sagittal plane and a plantar surface including a first cover component having a first internal cavity and being adapted to receive and cover a first portion of the prosthetic foot, a second cover component having a second internal cavity and being adapted to receive and cover a second portion of the prosthetic foot, and a means for detachably attaching the first cover component and the second cover component to the prosthetic foot. The first internal cavity has a first internal cavity contacting surface that directly contacts the first portion of the prosthetic foot, and the second internal cavity has a second internal cavity contacting surface that directly contacts the second portion of the prosthetic foot. A method for installing the prosthetic foot cover on the prosthetic foot.

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.

Systems and devices for use as lower leg prosthetic devices that include a foot portion having anterior and posterior ends and a first surface having a protrusion that protrudes therefrom adjacent the posterior end of the foot portion, has a semispherical or hemispherical surface with a passage therethrough extending laterally relative to the foot portion. The systems and devices further include a toe portion pivotally coupled to the anterior end of the foot portion, and a plate portion configured to couple to an attachment device and thereby be functionally secured to a user. The plate portion has a recess configured to couple with the protrusion of the foot portion. A cylindrical rod is located within the lateral passage of the protrusion and has ends protruding therefrom on oppositely-disposed of the protrusion. The plate portion is pivotally coupled to the ends of the rod on oppositely-disposed lateral sides of the protrusion.

A prosthetic foot, including a keel having a longitudinal axis. The keel includes a keel body including a heel portion, a forefoot portion, and an ankle portion positioned between the heel portion and the forefoot portion. The ankle portion includes a housing having a vertically oriented central axis. In addition, the prosthetic foot includes a coupling assembly disposed within the housing of the ankle portion. The coupling assembly includes a bearing member disposed about the central axis, a support sleeve concentrically disposed about the bearing member, and an embedding member disposed about the support sleeve. The embedding member includes a plurality of interlocking rings.

The disclosure provides apparatus and methods of use pertaining to a bidirectional biomechanical prosthetic finger assembly. One embodiment includes a metacarpophalangeal (MCP) pivot configured for swivelable attachment to a hand of a user, a distal coupler, and an articulation assembly rotatively coupled therebetween. A multiple-finger ring configured to receive a user's residual finger and at least one adjacent finger is disposed upon the articulation assembly, and may be adjusted to a target location based on a length of the residual finger. The articulation assembly is configured to utilize vertical movements of the residual and/or adjacent finger(s) within the multiple-finger ring to articulate the distal coupler within a plane parallel to an x-z plane, and the MCP pivot is configured to utilize lateral movements of the residual finger within the ring to articulate the distal coupler within a plane parallel to an x-y plane. Other embodiments are also disclosed.

The disclosure provides apparatus and methods of use pertaining to a prosthetic finger assembly. In one embodiment, the assembly includes a coupling tip and a distal ring coupled with the coupling tip. The assembly further includes a proximal ring coupled with the distal ring. A rocker formed in an H-shape with a first end forming a first split prong and a second end forming a second split prong may extend between the coupling tip and the proximal ring. The coupling tip, distal ring, proximal ring, and H-shaped rocker may all be hingedly connected such that movements of the residual finger within the proximal ring articulate the distal ring together with the rocker to articulate the coupling tip. Other embodiments are also disclosed.

The synergetic prosthetic system comprises of a knee and an ankle sleeve on the functional leg and a prosthesis on the amputated leg. Each sleeve comprises of a power supply, an accelerometer, a wireless transmitter and a wire connecting the accelerometer to the wireless transmitter. The prosthesis comprises of a power supply, a microcontroller, servo motors, a knee joint assembly, and an ankle joint assembly. A steel rod covered with a casing connects the knee and ankle joints. The accelerometer measures and transmits the angle of rotation of the functional knee and ankle joint to a microcontroller. The microcontroller pre-programmed with normal gait data pairs the data from the healthy leg and controls the servo motors. The servo motors, move the prosthetic joints to mimic a normal human gait.

High resolution active matrix nanowire circuits enable a flexible platform for artificial electronic skin having pressure sensing capability. Comb-like interdigitated nanostructures extending vertically from a pair of opposing, flexible assemblies facilitate pressure sensing via changes in resistance caused by varying the extent of contact among the interdigitated nanostructures. Electrically isolated arrays of vertically extending, electrically conductive nanowires or nanofins are formed from a doped, electrically conductive layer, each of the arrays being electrically connected to a transistor in an array of transistors. The nanowires or nanofins are interdigitated with further electrically conductive nanowires or nanofins mounted to a flexible handle.

A prosthetic device includes an internal frame assembled from multiple longitudinal members and multiple transverse members that are substantially planar in character and are arranged to be joined together. A medially arranged opening is defined in each transverse member, and is substantially registered with openings of adjacent transverse members to form a longitudinal passage, such as may be useful to receive an actuator and/or other items. At least some transverse members differ from one another in one or more of shape, length, or width. A covering member may be provided over the internal frame. Rear-facing gaps in transverse members may receive one or more elements such as dampers, batteries, or the like.
