Filed:

Aug 31, 1990

Appl. No.:

7/576228

Inventors:

Michael T. Wilson - Missouri City TX
David F. Jolly - Abrams WI

Assignee:

Syncor, Ltd. - Abrams WI

International Classification:

A61F 266

US Classification:

623 49

Abstract:

A prosthetic foot comprises a flexible planter member, a flexible dorsal member, and a posterior pylon member connected by ball and socket joints. Elastic snubbers and torsion resistors aid in controlling the movement of the three structural members relative to each other. During ambulation, the foot deforms elastically to generate approximately the same forces and feel to the user as would be generated by the skeleton, muscles, tendons, and ligaments of a natural foot.

Appl. No.:

7/031402

Inventors:

David F. Jolly - Houston TX

International Classification:

A61F 260

US Classification:

623 32

Abstract:

The present invention relates to an integral flexible elastic support member for securely gripping an orthopedic device such as a cast on a leg or for attaching an artificial leg to the residual lower limb of a human being having at least one above the knee amputation. The supporting member includes an adjustable body encircling portion having free ends which have attachment means, for detachably connecting the free ends together, and at least one integrally formed flexible cylindrical elastic sleeve portion descending downwardly from the body encircling portion to grip and provide support for at least one artificial leg. Optionally, the orthopedic member additionally includes a V-shaped adductor panel on the surface of the device to assist in positioning and with control of forces. Optionally, the supporting member also includes an opening within the adductor panel region to assist in the management of the forces. VELCRO. RTM. hook and loop attachment means, and an elastic neoprene/nylon composite fabric are preferred materials of manufacture.

International Classification:

A61F 278

US Classification:

623 32

Abstract:

The present invention relates to an integral elastic suspension sleeve for use with an artificial limb prosthetic device. Specifically, the invention is an integral flexible elastic support sleeve having two circular ends which encloses and securely grips the residual lower extremity portion of a human being who has had a below the knee (or below the elbow) amputation and also encloses and securely grips the top outer surface of the socket of a shin and foot (or forearm and hand) prosthetic device. The suspension sleeve has a smaller internal cylindrical-like panel which has a fabric surface having a low coefficient of friction. This fabric surface is in contact with the outer intersection line between the prosthetic device and the limb extremity of the human being. This sleeve is at between about 5. degree. and 45. degree. angle, and the described configuration results in improved mobility, decreased dermatological irritation to the wearer and enhances the longevity of the elastic suspension sleeve.
