Filed:

Apr 9, 2001

Appl. No.:

09/828671

Inventors:

Kerry E. Wilkinson - Chandler AZ 85226
Randall S. Whiteside - Phoenix AZ 85048

International Classification:

A61F 280

US Classification:

623 35

Abstract:

Prosthetic apparatus includes a pyramid adaptor and a pylon connected together by an outer sleeve, which may be an elastomeric element. The sleeve or element is clamped to both the pyramid adaptor and to the pylon to provide shock absorbing characteristics and to allow relative axial rotation between the pyramid adaptor and the pylon. Different configurations of sleeves are illustrated, and the use of a third clamp is also illustrated.

Appl. No.:

10/078298

Inventors:

Kerry E. Wilkinson - Chandler AZ 85226

International Classification:

G02B 2700

US Classification:

359614, 359454, 359599, 359601

Abstract:

An optical screen panel and a method of making an optical screen panel is disclosed. The panel includes layers or rows of alternating, or interleaved, light transmitting and light blocking or opaque elements, and is extruded. The layers or rows are in the form of relatively small ribbon elements which are generally parallel to the direction of viewing, and thus generally perpendicular to the front plane of the panel itself, which is the viewing surface of the panel. Several embodiments are shown, including panels with light directing elements and light scattering elements. The light directing and scattering elements may be embossed in the extruding process or they may be extruded as separate layers and secured to the layered panel post extruding. Angled and curved layers are among the several embodiments. Ultra violet protection may also be provided to the optical screen layered panel.

Inventors:

Kerry Wilkinson - Chandler AZ, US

International Classification:

A61F002/62

US Classification:

623/038000

Abstract:

A collar includes a counterbore for receiving a rim of a prosthetic leg tube. The collar is press fitted onto the tube, and a pyramid connector element is secured to the collar and the tube to connect the collar and tube to a user. Two different counterbore embodiments in the collar are disclosed, a tapered counterbore and a square counterbore. Set screws extend through aligned tapped apertures in the collar and tube.

US Classification:

623/052000, 623/055000

Abstract:

Prosthetic foot apparatus includes a flexible foot plate, an elastomeric block, and a tubular pylon element. The tubular pylon element includes an upper tubular portion, a partially flattened curved portion, and a generally flattened lower portion secured to the foot plate by an elastomeric block. The elastomeric block is configured to allow, with the pylon and the foot plate, inversion, eversion, dorsi flexion, and planar flexion movements of the apparatus to simulate ankle and toe movements of a normal foot. The foot plate and the tublar pylon allow for dorsi flexion and planar flexion movements, and the elastomeric block is appropriately configured to add inversion and eversion movements as well as dorsi flexion and planar flexion movements of the apparatus.

Inventors:

Kerry E. Wilkinson - Chandler AZ

International Classification:

A61F 266

US Classification:

623 52

Abstract:

Prosthetic foot apparatus includes a tubular element appropriately bent and flattened to provide desired flexibility. The extent of flexibility, and accordingly the extent of the bending and flattening of the tubular element provides desired stiffness or flexibility according to the desired characteristic, complementary of the user of the apparatus. Different embodiments are shown, including an embodiment which includes a separate foot plate secured to and extending into the foot portion of the tubular element.
