Abstract: A device is provided to allow adaptation of a prosthetic or robotic foot in the medial-lateral direction, including pronation and supination of the foot using a series of articulations. Articulations are permitted in the disclosed device due to linkage systems positioned at various locations of the prosthetic foot. In particular, the device includes multiple connected linkage systems each including upper and lower portions with an articulating contact surface designed for load carriage and stability. The point of contact between the contact surfaces of each linkage system comprises the position-dependent instantaneous center of rotation of the upper portion with respect to the lower portion. The device also includes a platform coupled between the linkage systems and a base.

Abstract: An electrode is supported on a prosthetic liner to communicate electrically with a residual limb. A housing is fixed to the liner, and is receivable in a socket in an installed position. A processor is installed in the housing in communication with the electrode. Electrical signal contacts are exposed at a distal end of the housing for contacting electrical signal contacts in the socket. The housing defines a ground current path that communicates with a ground contact in the socket.

Abstract: Prosthetic socket sealing systems and methods of use. Embodiments of the present invention include various combinations of sealing elements that are associated with a rigid prosthetic socket and act to seal the socket interior against air intrusion or escape via the open proximal end thereof. The socket interior may thus be evacuated for purposes of vacuum suspension or otherwise.

Abstract: A prosthetic cushion liner may include a fabric covering having an open end for introduction of a residual limb and a closed end opposite the open end. The prosthetic cushion liner may include a continuous layer of a gel composition residing on an interior surface of the fabric covering. The gel composition may include a plasticizing oil; one or more of a SEBS thermoplastic elastomer, a SEPS thermoplastic elastomer, a SEEPS thermoplastic elastomer; and a hydrogenated block copolymer.

Abstract: A liner interface and method of making the liner interface comprising attaching non-compressible deformable electrically conductive receptors to an inner surface of a fabric layer, placing the fabric layer into a female part of a molding machine, axially deforming the deformable receptors from their initial thickness with a male part of the molding machine, injecting a molten gel elastomer into the molding machine to completely surround and adhere to the receptors and inner surface of the tubular fabric layer, allowing the molten gel to cure, and removing the male part from the molding machine and allowing the axially deformed receptors to axially expand beyond the inner surface of the cured liner interface.

Abstract: A stable shock absorbing prosthetic foot that transfers energy between heel strike and toe-off. A toe plate is separated from one or more other plates by a bumper assembly located at each of the toe end and heel end of the foot. Certain embodiments of the shock absorbing foot of the present invention are designed for use with a prosthetic ankle. A torsion adapter may also be used to attach a prosthetic foot of the present invention to the remainder of a prosthesis.

Abstract: A conductive human interface has a fabric layer with an interior surface and an exterior surface. A soft coating overlies the interior surface of the fabric layer. An electrode or sensor is included to connect with a residual limb. A conductive path connects the electrode or sensor with an electrical connector which, in turn connects with a prosthetic or other assistive device. The conductive path includes a conductor having a section overlying the fabric layer. The overlying section of the conductor can be cord of conductive thread. A nonconductive support thread can extend through the fabric layer from the exterior surface to the interior surface, and further around the conductor to secure the overlying section of the conductor to the fabric layer.

Abstract: Prosthetic liners, prosthetic sockets and prosthetic suspension sleeves, as well as orthotic components, having enhanced thermally conductivity and/or enhanced heat absorption capabilities. Such components may be used in various combinations to create assemblies and systems that are operative to better transfer heat away from and/or absorb heat produced by residual or intact limbs of a user.

Abstract: Various systems and methods for removing perspiration from the interior of a donned polymeric prosthetic liner are disclosed.

Abstract: A prosthetic foot structure includes a primary foot member and a heel member. The primary foot member has a heel portion, a toe portion with a pair of toe sections separated by a gap, and an elongated intermediate portion configured as an arch extending downward from the heel portion toward the toe portion. The heel member includes a hollow cylindrical spring wall extending downward from the heel portion of the primary foot member. The primary foot member and the heel member are portions of a unitary body of material formed by additive manufacturing.

Abstract: Various embodiments of a system and method for sealing a prosthetic socket are disclosed. One example socket sealing system may comprise: a prosthetic socket having a proximal end, an expanded section, and an internal peripheral shoulder; a brim seal having an inner proximal end, an outer proximal end, and a distal end; a removable brim having a distal end; a liner; and a wicking sock; wherein prosthetic socket may be oriented radially outwardly of the outer proximal end of the brim seal, the outer proximal end of the brim seal may be oriented radially outwardly of the removable brim, the removable brim may be oriented radially outwardly of the inner proximal end of the brim seal, the inner proximal end of the brim seal may be oriented radially outwardly of the wicking sock, and the wicking sock may be oriented radially outwardly of the liner; and wherein the brim seal may be reflected about the distal end of the removable brim.
