Abstract

A prosthetic foot comprising a vacuum system configured to attach to a vacuum attachment apparatus and a residual limb. The prosthetic foot may comprise a resilient bottom member, a resilient top member, and a vacuum system. The resilient bottom member may comprise a front end and a rear end. The resilient top member may comprise a front end and a rear end and the front end of the resilient top member may be connected to the front end of the resilient bottom member. The vacuum system may be coupled to an underside of the rear end of the top member. The vacuum system may comprise a compressible member, a chamber located within the compressible member, a valve system received within the compressible member, a passageway connecting the valve system and the chamber, and an air return coupled to the valve system and the vacuum attachment apparatus.

Abstract

A mounting bracket for a prosthetic foot configured to attach to a residual limb, comprising an upper member, a lower member and compression torsion joint. The upper member comprises an upper flange, a mating post, and mounting portion configured to attach to the residual limb. The lower member comprises a mating portion, a lower flange, and a mounting portion configured to attach to the prosthetic foot. The compression torsion joint couples the upper member to the lower member and is configured to limit the vertical movement and torsional movement of the upper member with respect to the lower member.

Abstract

A prosthetic foot may comprise a resilient lower member, a resilient upper member and an upper bracket. The resilient lower member may comprise a front end, a middle, and a rear end. The resilient upper member may comprise a front end and a rear end. The rear end of the upper member is coupled to the rear end of the resilient lower member and the resilient upper member is positioned over the resilient lower member. The mounting bracket may comprise a front end and a rear end. The front end is coupled to the front end of the resilient upper member and the rear end is configured to attach to the residual limb of the user. The resilient lower member and resilient upper member of the prosthetic foot fit completely within a foot shell.

Abstract

A prosthetic foot may comprise a resilient member comprising an outer arced surface, a toe piece, a mid-stance support, and a heel support. The toe piece may be coupled to an anterior portion of the outer arced surface of the resilient member. The mid- stance support may be removably coupled to a middle portion of the outer arced surface of the resilient member. The heel support coupled to a posterior portion of the outer arced surface of the resilient member.

Abstract

A prosthetic foot comprises a resilient bottom member, a resilient top member, wherein the anterior top end is connected to the anterior bottom end of the resilient bottom member, and wherein the resilient top member is positioned over the resilient bottom member, and an elastomeric bumper member comprising a tapered surface configured to contact the resilient bottom member and attached to an underside of the posterior of the resilient top member. The prosthetic foot can further comprise a toe pad having a spacer coupled to, and creating space between, the bottom member and the top member, and an adhesive bonding one of the bottom member and one end of the top member, where the adhesive is commingled with the spacer between the first bottom end and the first top end.

Abstract

A prosthetic foot comprises a ground engaging bottom resilient member, a resilient heel member, and a resilient toe member that collectively circumscribe an open volumetric space. The members resilient compress to absorb compressive force throughout the entire stride of an individual utilizing the foot. The prosthetic foot stores energy during a heel strike phase of a gait cycle, and releases energy during a toe-off phase of the gait cycle in order to assist forward movement of a user. During the gait cycle, a loading response during the heel strike phase compresses the heel member and the toe member, and causes a deflection of the rear portion of the bottom member. Furthermore, an upward deflection of at least one of the bottom member and the toe member stores energy during the transition from the heel strike phase to the toe-off phase of the gait cycle.
