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 liner for application on a stump, the prosthetic liner including an elastic base, which has a proximal opening for insertion of the stump a receiving space, and a distal end. At least one pneumatic piston is arranged on the outer face of the prosthetic liner.

A system for powering a prosthetic arm is disclosed. The system includes at least one internal battery located in the prosthetic arm, at least one external battery connected to the prosthetic arm, and a master controller configured to connect either the at least one internal battery or the at least one external battery to a power bus to power the prosthetic arm.

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.

Various aspects of upper arm prosthetic system for a human subject having a body and a partial arm are described. According to one aspect, the system may comprise any one or more of a force amplification apparatus, a terminal unit apparatus, and/or an adjustable elbow apparatus. Each apparatus may be body-powered and/or comprise 3D printable structures. Related upper arm prosthetic apparatus, kits, methods, and systems also are described.

A sleeve generally shaped as a limb and an overlapping area of curvature formed in the sleeve extending a length of the sleeve. A clasp is formed from slicing the overlapping area of curvature the length of the sleeve along a line substantially perpendicular to a transverse plane to create a first end and a second end. The sleeve is openable to separate the first end and the second end of the clasp for fitting the sleeve around the prosthesis and latchable by fitting the first end of the clasp over the second end of the clasp.

An upper extremity prosthesis for placement on a residual limb of a person that includes an elongated member having a first end and an opposite second end and also includes an outer prosthetic shell having a first end and an opposite second end. The prosthesis also includes at least a first support and a second support, wherein the first support and the second support surround and are fixedly coupled to the elongated member at first and second attachment points, respectively. The outer prosthetic shell thus surrounds and is coupled to the first support and the second support. The first support and the second support can be a disk-shaped structure through which the elongated member passes.
