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.

The invention relates to a prosthetic foot with a housing (12) on which a connector (15) for a below-knee prosthesis can be arranged, with a forefoot (21) and a heel (43), wherein the housing (12) and the forefoot (21) are connected by at least one forefoot spring element (28), wherein the forefoot (21) and the heel (43) are connected by at least one sole spring element (41), and wherein the heel (43) and the housing (12) are connected by at least one heel spring element (30), wherein the end portions belonging to the at least one forefoot spring element (28) and to the at least one sole spring element (41), and assigned to the forefoot (21), are positioned relative to each other with at least one holding mechanism (34) in such a way that the at least one forefoot spring element (28) and the at least one sole spring element (41) are guided movably relative to each other along their longitudinal axis during a rollover movement.

Composite materials with certain functional or securement parameters are provided herein. Layered composite prosthetic with spring layers and composite rivets are provided. Fiber reinforced layers are grouped into keel, sole plate or other component and these components are configured to provide a spring action for the prosthetic alone or in combination. One or more composite rivets are installed to secure components together.

Blade-type prosthesis assemblies include a socket securable to a wearer of the prosthesis assembly and a blade securable to the socket. The blade has a blade body extending between a blade bottom and a blade top. The assembly further includes a base plate securable to the blade bottom. The base plate includes a shroud retainer element. The assembly further comprises a blade shroud covering at least a portion of the blade body and securable to the shroud retainer element and at least one of the socket and the blade body.

A prosthetic foot comprises an attachment member and two or more flexible members. The attachment member can include a connector configured to connect the attachment member to a user or another prosthetic device. The two or more flexible members can be rotatably attached to the attachment member by rotatable joints such that the flexible members can both rotate and flex relative to the attachment member when the prosthetic foot contacts the ground.

A prosthetic system includes a prosthetic foot having an upper foot element with a concave-forward facing portion and foot portion extending forwardly therefrom. An intermediate foot element is disposed below the upper foot element and has a front portion coupled to the foot portion of the upper foot element. A lower foot element is disposed below the intermediate foot element. A pump system is coupled to the prosthetic foot and comprises a pump mechanism including a housing defining a cavity, and a membrane situated in the cavity. The pump mechanism is movable between an original configuration and an expanded configuration. An arm member is connected to the pump mechanism and operatively coupled to the intermediate foot element. The arm member is arranged to move the pump mechanism toward at least the expanded configuration upon movement of the intermediate foot element relative to the upper foot element.

Systems and method for monitoring gait dynamics are disclosed. The performance of an orthotic or prosthetic device or other device associated with a limb may be measured based on the resistance of a bending sensor. Data from the sensors is gathered or processed, particularly for purposes of alignment, safety, failure, usage, selection, and artificial proprioception. Information relating to the device may be outputted visually or auditorily to an individual.

The invention relates to a method for producing an artificial foot, comprising a medial plane (M) in a longitudinal axis, in which a nominal foot length (1) is defined as a distance from a heel to a foot tip of a natural foot replaced by the artificial foot, and designed having a top side connecting piece (4) for torsionally rigidly connecting a foot insert (2) extending substantially over the length of the foot (1), and contacting two contact surfaces (6, 7) over the length (1), of which a first heel side contact surface (7) is located in the heel area and a second hall side contact surface (6) is located in the hall area, and designed so that the connecting part (4) is connected to the contact surfaces (6,7) of the foot part by means of spring connections.
