A prosthetic foot cover for a prosthetic foot having a sagittal plane and a plantar surface including a first cover component having a first internal cavity and being adapted to receive and cover a first portion of the prosthetic foot, a second cover component having a second internal cavity and being adapted to receive and cover a second portion of the prosthetic foot, and a means for detachably attaching the first cover component and the second cover component to the prosthetic foot. The first internal cavity has a first internal cavity contacting surface that directly contacts the first portion of the prosthetic foot, and the second internal cavity has a second internal cavity contacting surface that directly contacts the second portion of the prosthetic foot. A method for installing the prosthetic foot cover on the prosthetic foot.

Apparatus and method for a prosthetic foot cover

Prosthetic feet are described comprising a curvilinear spring element, including a rounded portion transitioning between upper and lower extensions, the upper extension including a mounting section/region between the curved portion and a distal end of the upper extension. At least one leaf spring element spans a gap between the upper and lower extension sections, and a resilient footbed is attached to the lower extension. Such feet are typically set within a cosmetic cover for and fit within a shoe for use.

High-performance multi-component prosthetic foot

A prosthetic device including an upper member having an upper end and a lower end, a wave member having a toe end and a heel end, and a third member having a proximal end and a distal end. In the preferred prosthetic device, the toe end of the wave member is fixedly attached to the upper member and the heel end of wave member is adapted to be deflected.

Lower limb prosthetic device with a wave spring

A foot prosthesis having improved rollover and stability. The prosthesis includes a first plate and a mounting block having a mounting portion configured to be coupled to a user of the prosthesis, an attachment portion and a gap portion, with the mounting block attached to the first plate at the attachment portion with a gap between the mounting block gap portion and the first plate. Also included is a resilient element positioned at least partially within the gap, the resilient element configured generally to dissipate stress in the first plate and control deflection between the first plate and the mounting block. The mounting block may be substantially rigid with the area of the first plate attached to the mounting block becoming substantially rigid while the remainder of the first plate is at least partially flexible. The resilient element may be interchangeable to adjust performance of the prosthesis.

Lower leg prosthesis with improved roll over

An improved lower leg prosthesis is disclosed for providing an improved performance, including improved stability and improved multi-axial compliance. The prosthesis includes a two-part lower foot plate, incorporating a forefoot plate and a heel plate, and an upper foot plate that is attached to the forefoot and heel plates by a two-part intermediate elastomeric layer. Forming the lower foot plate and the elastomeric layer each in two parts ensures that the forefoot plate and heel plate function substantially independently of each other, which leads to substantially improved cushioning at heel strike and to improved stability throughout the gait cycle.

Lower leg prosthesis

An improved lower leg prosthesis is disclosed that, during use, provides an improved dynamic feel at heel strike and that provides improved inversion/eversion compliance. The prosthesis includes an elongated pylon having an upper, generally vertical section and a lower, forwardly oriented foot section, and it further includes a generally horizontally oriented foot plate disposed beneath the pylon and including a heel section projecting a substantial distance rearwardly of a vertical pylon axis. An elastomeric layer is interposed between the pylon and the foot plate, extending along substantially the entire length of the heel section of the foot plate, for attaching the pylon and foot plate together. During use of the prosthesis, at heel strike, upward deflection of the foot plate's heel section is limited in substantial part both by the stiffness of the heel section, itself, and by compression of the portion of the elastomeric layer disposed rearwardly of the vertical pylon axis.
