A prosthetic foot with a structural component having a proximal attachment member for fastening the prosthetic foot to a below-knee tube, a below-knee shaft or a prosthetic knee joint, with a forefoot portion secured or formed on the structural component, and with a heel-side spring-damper system which is assigned to the structural component and which is compressed at a heel strike and bears on a sole-side guide element. The structural component is designed as a leaf spring which extends in a posterior direction from the proximal attachment means, and forms an arch and is guided in an anterior and distal direction, wherein the arch protrudes posteriorly beyond the guide element.

Prosthetic foot including a heel cap and interchangeable heel-side spring-damper

A prosthetic foot is provided with a forefoot spring, a heel spring and a base spring. The base spring is connected to the heel spring and to the forefoot spring. The base spring has receiving means for the forefoot spring and the heel spring, into which receiving means the heel spring and the forefoot spring can be inserted. The heel spring is connected to the forefoot spring via a coupling element, and the coupling element extends forwards along the forefoot spring at least via one portion thereof.

Prosthesis

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

A vacuum pump having shock absorption and controlled rotation for use in an artificial limb. The pump includes a housing having a first chamber, and a shaft configured to be received by and to reciprocate within the first chamber, the housing and shaft forming a pump chamber. A piston may be coupled to the shaft and positioned within the pump chamber, and intake and exhaust ports are fluidly coupled to the pump chamber. Rotational structure is mounted with respect to the pump to provide controlled rotation of the shaft relative to the housing, and shock absorption structure is included within the pump to provide shock absorption for the shaft. Both a pneumatic spring and a mechanical spring element may be provided for the shock absorption structure. An optional adapter couples the shaft to the pylon of an integral pylon prosthetic foot.

Vacuum pump with shock absorption and controlled rotation for prosthetic devices

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.
