Abstract: A prosthetic digit can include a proximal segment connected to an intermediate segment about a first axis of rotation and a distal segment connected to the intermediate segment about a second axis of rotation. A linkage can be connected to the proximal segment about a third axis of rotation and can couple the proximal segment to the distal segment. The linkage can be configured such that a distal end of the distal segment to rotate toward the proximal segment about the second axis of rotation when the intermediate segment is rotated in a palmar direction about the first axis of rotation. A unidirectional lock can allow the intermediate segment to rotate about the first axis of rotation in a palmar direction but not in a dorsal direction. A release mechanism can release the unidirectional lock to allow the intermediate segment to rotate in the dorsal direction.

Abstract: A prosthetic foot includes a cap, a retaining element and a plurality of blades. Each of the plurality of blades includes a proximal portion coupled with the cap, a middle portion coupled with the retaining element and a distal portion extending outwardly from the retaining element.

Abstract: A universal digit is formed to be attachable to the residual digit of a patient, and to have a lockable joint, so as to provide considerable utility and flexibility. The structure of the joint member allows the universal digit to be easily adjusted and manipulated so that the extension portion can be locked into multiple positions by easily manipulating adjustment buttons. The extension is rotatable about a first longitudinal axis, and is further rotatable about a transverse axis which is perpendicular to the longitudinal axis. The joint structure thus has three dimensions of movement and provides a significant number of diverse options for positioning of the extension. Unique locking mechanisms within the various structures allow the universal digit to be rigidly held in the desired position, thereby increasing the utility for a patient/user.

Abstract: An interface for use in conjunction with a prosthetic device is formed of a pliable material which is configured to support the necessary connection to a residual limb when used. The interface further has an internal surface structure that includes several stepped indentations which provide a more efficient and effective product. The stepped indentations have a dimension which decreases as the distance from the interior surface increases. In some embodiments, the indentations are shaped as an octagon, with each step also being octagonal. Other shapes are also contemplated. Also, the steps of the indentations could be uniform or irregular.
