An adjustable seal system, seal component for use in the system, and method are provided for forming a sealing interface between a residual limb and a prosthetic socket. The seal component is selectively placed over the outer surface of a suspension liner including a plurality of seal bands, which the seal component may removably and securely engage.

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 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.

An adjustable prosthetic limb connection with a mounting plate, an alignment mechanism, and a lower connector. The mounting plate is configured to attach to a prosthetic limb socket, the alignment mechanism is configured to couple with the mounting plate, and the lower connector is configured to attach to the alignment mechanism and to a prosthetic limb. The alignment mechanism is configured to allow adjustment of the alignment of the lower connector with respect to the mounting plate with at least two linear degrees of freedom. The alignment mechanism may comprise a base plate and a linear slide. The base plate is configured to be secured against the mounting plate and may have first and second rows of teeth. The linear slide may be positioned between the base plate and the mounting plate and may have first and second ridges configured to interface with the first and second rows of teeth.

An intra-frame positioning sling may be disposed internally within a prosthetic socket frame. The sling may include one or more proximal suspension portions adapted to suspend from a proximal aspect of the frame and a tensioning system. The sling may include a first longitudinal side with one or more proximal suspension portions and an opposite longitudinal side that includes the residual limb interfacing or force application portion of the sling. When the tensioning system is tensioned, the sling is pulled toward the first longitudinal side of the prosthetic socket frame. A set of two positioning slings may be rigged in a transfemoral prosthetic socket frame; one sling applies force on a medial side of a hosted residual limb, and the other sling applies force on the lateral side.

A transtibial prosthetic socket frame may include a distal base assembly having a base plate, a carriage configured to support a socket suspension arrangement, and a distal prosthetic component connector. The distal base assembly supports a set of struts that includes two anterior struts and a single posterior strut. The set of struts and distal base assembly collectively define a prosthetic socket cavity having a central longitudinal axis and a residual limb hosting volume. The distal prosthetic component connector has a connecting adapter that is rotatable with respect to the prosthetic socket, and moveable with respect to the base plate between being aligned with the prosthetic socket's central longitudinal axis and a position offset therefrom.

The invention relates to an orthopedic knee joint, comprising an upper part (2), on which upper connecting means (20) are disposed, a lower part (3) pivotally supported on the upper part (2), connecting means for orthopedic components (4), and a stop ( ) for delimiting an extension movement, wherein the stop (7) is configured displaceably and coupled to an adjusting device (64), which is coupled to a control device (6), which actuates the adjusting device (64) as a function of sensor data and changes the position of the stop (7).

The invention relates to a prosthesis assembly, comprising an outer stem (10) provided with a proximal opening (11), and at the distal end (12) thereof is provided with a connecting means (13) for fastening an additional component, and which is formed of a material that is rigid in the longitudinal extension thereof, in which at least one slit (14) extending at least partially in a longitudinal direction is inserted in order to allow deformation in a radial direction. The prosthesis assembly further comprises an inner stem (20) made of a flexible material and provided with a proximal opening (21), at least one tensioning device (30) that is affixed to the outer stem (10) and can be accessed by way of a diameter change of the outer stem (10). At least one electrode (40) is displaceably fastened to a side of the outer stem (10) that is facing the inner stem (20).

An adjustable seal system, seal component for use in the system, and method are provided for forming a sealing interface between a residual limb and a prosthetic socket. The seal component is selectively placed over the outer surface of a suspension liner including a plurality of seal bands, which the seal component may removably and securely engage.

A prosthetic system includes a prosthetic foot having an upper foot element with a concave-forward facing portion and foot portion extending forwardly therefrom.
