A prosthetic device and related methods having height adjustment features. A prosthetic foot includes an elongate support member comprising fiber reinforced material and having a support surface configured to rest upon a ground surface prior to use, an adapter mounted to the support member and configured to secure the prosthetic foot to another prosthetic device, and a height adjustable feature configured to adjust a height of the adapter relative to the support surface.

A prosthetic system includes a prosthetic foot having an upper foot element with a concave-forward facing portion and foot portion extending forwardly therefrom. An intermediate foot element is disposed below the upper foot element and has a front portion coupled to the foot portion of the upper foot element. A lower foot element is disposed below the intermediate foot element. A pump system is coupled to the prosthetic foot and comprises a pump mechanism including a housing defining a cavity, and a membrane situated in the cavity. The pump mechanism is movable between an original configuration and an expanded configuration. An arm member is connected to the pump mechanism and operatively coupled to the intermediate foot element. The arm member is arranged to move the pump mechanism toward at least the expanded configuration upon movement of the intermediate foot element relative to the upper foot element.

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.

A prosthetic connector system for use with a prosthetic socket having a distal end includes a plate defining a plurality of holes and attachable to the distal end of the prosthetic socket. A component is removably attachable to the plate via the plurality of holes and arranged to connect a prosthesis to the prosthetic socket. The plate defines an outer periphery having an asymmetrical configuration contoured to substantially correspond to at least a portion of the component when the component is attached to the plate via at least some of the holes.

An expandable wall prosthetic socket configured with at least one retention ring in the socket wall and a telescoping element which interacts with the retention ring to allow the telescoping element to translate inwardly and outwardly through the socket wall, via the retention ring, such that the telescoping element is applying a force on the residual limb.

One embodiment provides for a fixed retention ring that is installed into the side of the socket wall. The retention ring is laminated into or bonded to the layered composite forming the socket wall. A telescoping element is installed through the retention and makes contact with, or is connected to, a force applicator plate. As the telescoping element translates inwardly, the telescoping element makes contact with (or pushes on) the force applicator such that the force applicator produces the load on the residual limb.

Additional embodiments provide for such features as a rotating retention ring, a two part panel with a retention ring and force applicator, and a force applicator designed into a prosthetic silicone liner.

A hinged connecting device comprising a damping mechanism intended to counter a predetermined resistance at least during bending of the prosthesis (1), by replacing the muscle groups usually used for this purpose. The damping mechanism (200) is capable of being switched between a first operating mode (M1), selected by default, in which the value of the resistance corresponds to a first maximum value (Vmax), and a second operating mode (M2), that can be actuated only in a hyperextension position (P0) of the prosthesis (1), in which the resistance value corresponds to a second minimum value (Vmin); and the hinged connecting device (2) moreover comprises a fully mechanical locking system (3), arranged in order to allow the second operating mode (M2) to be activated only when the inclination of the tibial part (102) exceeds a first predetermined oriented angle (X1) relative to the vertical.

The invention relates to a prosthetic foot component comprising: a. a proximal fastening system for securing the prosthetic foot component to a proximal component or to a patient; b. a retaining portion situated distally relative to the fastening system and connected to the latter; and c. a main spring extending in a front-foot region and coupled to the retaining portion, wherein: said retaining portion is mounted on the main spring to tilt on the sagittal plane; and a posterior limiting element, which limits the displacement of the retaining portion away from the main spring, is provided between the main spring and the retaining portion.

A percutaneous collar is made up of a central rigid ring and a flexible mesh inside a microporous silicone disc. The volume of the disc has a three-dimensional network of interconnected micropores forming microchannels connecting both external faces of the disc through the external micropores to the internal flexible mesh wherein the flexible mesh is formed by crossed longitudinal and radial elements or plates which form a plurality of holes.

A movable joint for use in a prosthetic or orthopedic system includes first and second joint sections arranged to rotate relative to one another. At least one shaft member is attached to and arranged to rotate relative to the first or second joint sections. A translating member is attached to the at least one shaft member. Translation of the translating member along a length of the at least one shaft member drives rotation of at least the first joint section and the second joint section.

A foot prosthesis that includes at least one spring element, an attachment member, and a heel member. The at least one spring element has a toe end portion, a heel end portion, an upper surface, and a lower surface. The attachment member is mounted to the upper surface and is configured to connect the foot prosthesis to a lower limb prosthesis component. A position of the attachment member is adjustable along a length of the at least one spring element. The heel member is mounted below the lower surface of the at least one spring element, and a position of the heel member is adjustable along the length of the at least one spring element.
