Prosthetic feet that allow for heel height adjustment and/or provide metatarsal joint functionality to more closely mimic natural human feet are provided. A prosthetic foot can include an ankle module having a locking mechanism configured to lock the heel at a particular height. The prosthetic foot can also include a toe region that adapts to varying heel heights. The ankle module and/or locking mechanism can be adjusted, controlled, and/or locked via a hydraulic mechanism. The toe region can curve upward relative to a portion of the foot proximal of the toe region.

A prosthetic cover for a prosthetic support element can include a substantially cylindrical hollow body with a first end and a second end and sized to fit around a support element of a prosthesis. A first flexible end seal and a second flexible end seal can each attach with the substantially cylindrical hollow body at the first and second ends, respectively, and connect the hollow body with the support element of the prosthesis by deforming about the support element when the prosthetic cover is installed around the support element.

A prosthesis cosmetic having a main part made of a foam material and/or composite fiber material and a cavity formed in the main part for receiving a prosthesis component, wherein the main part has an outside facing away from the cavity, on which outside a textile layer is arranged, an adhesive being applied on the inside of the textile layer facing the main part and the textile layer being adhered or laminated on the outside of the main part.

The disclosure provides apparatus and methods of use pertaining to a bidirectional biomechanical prosthetic finger assembly. In one embodiment, the assembly includes an eccentric metacarpophalangeal (MCP) pivot configured for swivelable attachment to a hand of a user, a distal coupler, and an articulation assembly rotatively coupled therebetween. A ring configured to receive a user's residual 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 finger within the 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.

This application discloses a dexterous hand. The dexterous hand uses the anatomical structure of human hands for reference. The joints adopt dual-actuator antagonistic drive, which gives consideration to both compliant operation and robustness. The tendon joint and tendon sheath fixator are used for easy disassembly of hands and wrists. The metacarpophalangeal joints of each finger have the DOF of circumduction of, so that the fingers can automatically adapt to the complex surface. The axes of the multi-degrees of freedom joints are orthogonal, which is beneficial to control and motion planning calculation. The dexterous hand is ideal for handling objects of complex shape smoothly, facilitating production, disassembly and maintenance.

The invention relates to a sensor support (10) for arranging on a prosthesis, comprising a main part (20) for receiving sensors, said main part (20) having a sensor section (25) comprising sensors. The main part (20) has a holding section (30) for holding the main part (20) on a prosthesis part and a knitted fabric tube (21). The holding section (30) has a first knitted structure (32) which allows a secure hold of the main part (20) on the prosthesis part, and the sensor section (25) has a different knitted structure (27) which allows a secure positioning of the sensors relative to the prosthesis part.

A prosthetic cover (104) for a prosthetic support element (102) can include a substantially cylindrical hollow body (106) with a first end and a second end and sized to fit around a support element of a prosthesis. A first flexible end seal (108) and a second flexible end seal (110) can each attach with the substantially cylindrical hollow body at the first and second ends, respectively, and connect the hollow body with the support element of the prosthesis by deforming about the support element when the prosthetic cover is installed around the support element.

A nipple implant system wherein a nipple prosthetic device is attached to a microdermal anchor without the need for invasive surgery. The microdermal anchor is inserted through a hole punched at a selected locus. The nipple prosthetic device is configured for attachment to the microdermal anchor. An areola may be tattooed around the locus or the nipple prosthetic device may include a skirt simulating an areola to make the construction complete.

A prosthetic knee can include a variable-torque magnetorheological (MR) actuator assembly or braking system, a frame and an electronics assembly or system that also serves as a mount for the knee actuator and facilitates in monitoring and controlling the operation of the knee actuator. The prosthetic knee system advantageously provides resistive forces to substantially simulate the position and motion of a natural knee joint during ambulation and/or other locomotory activities performed by the amputee. The prosthetic knee can be enclosed in a waterproof compartment. An outer cover can be configured to fit around the waterproof cover of the prosthetic knee.

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.
