Publication number: 20030120354Abstract: A prosthetic foot includes an adapter element securable to a residual limb, a foot plate having a heel portion and a toe portion along the length thereof, at least one toe spring connected between the adapter element and the toe portion of the foot plate, and a heel spring connected between the adapter element and the heel portion. The heel spring may be a leaf spring or a tube type shock absorber. The concave side of the leaf spring exhibits a plurality of transverse ribs. Alternatively, a tubular pylon may have a collar mounted thereon for movement along the length of the pylon. A toe spring and a heel spring extend from the collar to form toe and heel portions of the prosthetic foot. A further heel spring is connected between the heel portion and another end of the pylon, and a non-extensible band extends between the heel portion and the collar. As another alternative, a tubular pylon has one end securable to a residual limb, and a collar is mounted to the pylon for movement along the length of the pylon.Type: ApplicationFiled: January 29, 2003Publication date: June 26, 2003Applicant: OHIO WILLOW WOOD COMPANYInventors: Jeffrey L.

Patent number: 6576022Abstract: An adjustable connector assembly includes a circular one-piece base member adapted to be attached to a socket coupler for an amputee's residual limb. The base member has axially projecting spaced track portions which receive therebetween a circular flange of a slidable and rotatable one-piece connector member. A pair of clamping plates receive screws threaded into the track portions for releasably clamping the flange to the base member. In one embodiment, the connector member has a dome surface and a four sided boss projecting from the flange. In another embodiment, the connector member has a projecting annular collar having peripherally spaced threaded holes. The base member and connector member are adapted to be machined from solid titanium bar stock.Type: GrantFiled: March 22, 2002Date of Patent: June 10, 2003Assignee: Bulldog Tools Inc.Inventors: Wilbur N. Meyer, Robert B. Meyer

Patent number: 6562075Abstract: A prosthetic foot incorporate a foot keel and a calf shank connected to the foot keel to form an ankle joint area of the prosthetic foot. The foot keel has forefoot and hindfoot portions and a relatively long midfoot portion extending between and upwardly arched from the forefoot and midfoot portions. The calf shank includes a downward convexly curved lower end which is attached at a portion thereof to the keel midfoot portion by way of an adjustable fastener arrangement. The foot has biplanar motion capability and, in a preferred form, also has high low dynamic response characteristics. The adjustable fastener arrangement permits adjustment of the alignment of the calf shank and the foot keel with respect to one another in the longitudinal direction of the foot keel for tuning the performance of the prosthetic foot.Type: GrantFiled: March 30, 2001Date of Patent: May 13, 2003Inventors: Barry W. Townsend, Byron K. Claudino

Publication number: 20030004582Abstract: A multi-axis prosthetic ankle includes a bottom component connected to a prosthetic foot, a lower leg connection component connected to a prosthetic lower leg, an elastomeric material securely connecting the bottom component with the lower leg connection component, and a mechanical device suspended in the elastomeric material. The mechanical device is formed of a first bracket connected to the bottom component and a second bracket connected to the lower leg connection component. The first and second brackets interlockingly float in the elastomeric material, and are not in direct contact with one another, thereby permitting relative movement of the bottom component and the lower leg connection component by deformation of the elastomeric material. At least one mechanical stop is positioned to prevent the relative angular movement of the ankle from deforming the elastomeric material beyond the elastic limit thereof.Type: ApplicationFiled: June 29, 2001Publication date: January 2, 2003Applicant: OHIO WILLOW WOOD COMPANYInventors: Chi L.

Publication number: 20020193887Abstract: A lock adapter is adapted to connect a residual limb liner with locking pin to a transfemoral prosthetic limb. The lock adapter is formed of a bracket having a first end and a second end, and preferably has a generally S-shaped configuration. The first end of the bracket has a first mounting face against which the lock is to be secured. The second end of the bracket is provided with a second mounting face against which the prosthetic limb is to be secured. The bracket being is formed so that the first and second mounting faces are spaced apart from one another, and may optionally be angled relative to one another. Methods of forming transfemoral test and final sockets are provided.Type: ApplicationFiled: June 17, 2002Publication date: December 19, 2002Inventor: Verner M. Swanson
