A prosthetic device includes a flexible interface configured to conform to a residual limb of a user, a prosthetic socket including an outer shell more rigid than the flexible interface and positioned external to at least a portion of the flexible interface, and one or more vibrational devices placed in connection with the flexible interface to impart vibration to the residual limb.

A prosthetic socket for a residual limb of the lower extremity or upper extremity of an individual person is provided. The residual limb has particular dimensions and anatomical contours; the prosthetic socket has dimensions and contours that fit the dimensions and contours of the residual limb. The prosthetic socket may also fit in a manner that is biomechanically appropriate for the individual. The prosthetic socket may be an assembly from groups of components that include (a) struts arranged longitudinally with respect to the residual limb, (b) proximal brim members arranged proximally to the struts and connected thereto; and (c) distal socket members disposed at the distal base of the prosthetic socket. The socket components within these groups may be modular in that they can vary with respect to dimensions and/or contours, and yet have common connecting features that permit assembly of the components together to form the prosthetic socket.

A unibody transtibial prosthetic device includes a socket personalized for a specific patient’s residual limb. A pylon extends from the socket, the pylon being a unitary polymer structure of interconnected elongated supports having open spaces therebetween. The device also includes a foot-ankle complex, the foot-ankle complex being a unitary polymer extending from the pylon, the foot and ankle unitary structure being shaped to provide multi-axial dynamic flex to enable dorsiflexion, plantar flexion, inversion and eversion motion for smooth symmetric gait performance and energy capture and return. The socket, pylon and foot-ankle complex are portions of a unibody.

A multi-component frame includes a first component made from a rigid structural material and a second component connected to at least an end portion the first component. The first component is constructed from a metal or metal alloy, and the second component is constructed from a material different from the first component. The first and second components form at least part of a length of the multi-component frame.

A flexible prosthetic inner socket that resides inside of a rigid prosthetic socket that is fabricated by forming a sized, injection molded, flexible inner pre-socket. The flexible inner pre-socket includes a body formed with an opening and an enclosed end. The Pre-socket can be heated and stretched over a prosthetic residual limb model and then a prosthetic rigid socket can be formed over it. It can also be heated and vacuum-formed inside of an existing hard prosthetic socket in order to provide global volume reduction intended to make the rigid prosthetic socket fit tighter onto the residual limb. The opening of the flexible inner socket may be trimmed after the formation to fit contours of an opening of the rigid prosthetic socket.

An improved composition for a thermoplastic elastomer that is used in a product that touches the skin. The thermoplastic elastomer contains a styrene block copolymer, a plasticizing oil, and CBD oil. The plasticizing oil and the CBD oil, in combination, comprise at least eighty percent of the thermoplastic elastomer by weight. The plasticizing oil and the CBD oil have the same, or similar, molecular weights. In that manner, the plasticizing oil and the CBD oil can form a homogenous mixture. The CBD oil saturates the thermoplastic elastomer and will slowly bloom out of the thermoplastic elastomer over time. The migration of the CBD oil brings the CBD oil to the exposed surfaces of the thermoplastic elastomer, therein enabling the CBD oil to be absorbed by the skin.

An adjustable seal system includes a seal component having a body having an outer surface defining a socket sealing portion arranged to engage and form an airtight seal with an interior surface of a prosthetic socket. The inner surface of the body defines a liner sealing portion arranged to frictionally engage and seal with an outer surface of a prosthetic liner. The liner sealing portion defines a sealing length extending in a proximal direction from an end of the socket sealing portion and terminating at a proximal edge on the body. The length of the liner sealing portion is between about 25 mm and about 35 mm and is selected in relation to the socket sealing portion to vary tractions at the inner and outer surfaces of the seal component.

Breathable residual-limb system that admits air and allows sweat to evaporate from the surface of the residual limb. In an embodiment, the system comprises a liner sock to be worn on the residual limb, and comprising air-permeable textile forming a substantially cylindrical portion that is closed on a distal end and open on a proximal end and comprising an internal surface and an external surface. The liner sock further comprises a friction-interface material that covers only a portion of the internal surface of the air-permeable textile, such that, when worn on the residual limb, the friction-interface material contacts a surface of the residual limb, and an uncovered portion of the air-permeable textile which the friction-interface material does not cover allows air to pass between an external environment of the liner sock and the surface of the residual limb.

The first component is constructed from a metal or metal alloy, and the second component is constructed from a material different from the first component. The first and second components form at least part of a length of the multi-component frame.
