A hydraulic ankle assembly to be used by a user, wherein the ankle assembly includes a base configured to be attached to a spring assembly, a hydraulic cylinder rotatably attached to the base and configured to dampen rotation of the hydraulic ankle assembly, and a prosthetic adapter portion rotatably attached to the base and the hydraulic cylinder and configured to be attached to a prosthetic worn by the user. The base, the hydraulic cylinder, and the prosthetic adapter portion define a force triangle that defines an axis of rotation of the hydraulic ankle assembly. The axis of rotation is positioned in line with the center of mass of the user when the user is standing. The force triangle reduces forces on the hydraulic cylinder.
A prosthetic device and related methods having height adjustment features. A prosthetic foot includes an elongate support member comprising fiber reinforced material and having a support surface configured to rest upon a ground surface prior to use, an adapter mounted to the support member and configured to secure the prosthetic foot to another prosthetic device, and a height adjustable feature configured to adjust a height of the adapter relative to the support surface.
A prosthetic device includes an elongate support member of carbon filament material having a first surface, and an adapter. The adapter includes a compressible member, a base portion having a contact surface arranged to contact the first surface of the support member, a cavity sized to receive the compressible member, and a connector portion extending from the base portion and configured to releasably secure the prosthetic foot to a prosthesis, wherein application of a force to the connector portion compresses the compressible member to dampen movement of the base portion relative to the support member until the contact surface contacts the first surface.

A prosthetic foot includes a base spring, a top spring assembly, a connector assembly, and a heel cushion. The top spring assembly includes first and second spring members, and first and second bond connections. The second spring member extends parallel with and spaced apart from the first spring member. The first bond connection is between distal ends of the first and second spring members, and the second bond connection is between a distal end of the second spring member and a top surface of the base spring. The top spring assembly has a first portion arranged horizontally, and a second portion arranged vertically. The connector is connected to a proximal end of the top spring assembly to connect the prosthetic foot to a lower limb prosthesis. The heel cushion is mounted to the base spring at a location spaced forward of a heel end of the base spring.

Methods and apparatus are disclosed relating to a mechanical vacuum socket pump (100) used to establish a vacuum in a socket of an artificial limb. In one case, the pump includes a housing (102) within which two pistons (104, 106) coaxially reciprocate. A surface of each of the pistons is linked hydraulically, such that driving one piston causes movement of the other piston through a hydraulic chamber. One piston is also linked to a pneumatic chamber such that movement of that piston draws air from a limb socket or expels air to the atmosphere upon movement of the piston's pneumatic surface. The surface area of the hydraulic surface of this piston is significantly less than the surface area of the pneumatic surface, so a small volumetric displacement of hydraulic fluid may cause a large displacement of air. Thus, the pump efficiently pumps air with minimal compression and extension of the pump as a whole.
A cervical collar (100) provides height adjustment using a locking member (108) disposed on a height adjustment member (122) extending through a height adjustment aperture (120). As the locking member is moved between locked and unlocked positions, ridges (142, 144) on a main collar body and on a chin support member may be interlocked or allowed to slide over each other from one desired position to another, thereby providing a height adjustment mechanism for the cervical collar.
A foot prosthesis that includes at least one spring element, an attachment member, and a heel member. The at least one spring element has a toe end portion, a heel end portion, an upper surface, and a lower surface. The attachment member is mounted to the upper surface and is configured to connect the foot prosthesis to a lower limb prosthesis component. A position of the attachment member is adjustable along a length of the at least one spring element. The heel member is mounted below the lower surface of the at least one spring element, and a position of the heel member is adjustable along the length of the at least one spring element.
A hybrid seating cushion (200) made up of a cushion base (202) and a cushion insert (220). The cushion base (202) has a seating surface (204) in which a void (214) in or extending through the cushion base (202) is formed. A cushion insert (220) such as an air bladder or fluid sack is positioned within the void (214). A lip (218) or upper surface around an opening (212) in the void (214) overhangs at least a portion of the cushion insert (220), thereby minimizing the size and corresponding negative effects of a transition area where the base (202) and the insert (220) overlap.

A foot prosthesis (100) having improved rollover and stability. The prosthesis (100) includes a first plate (130) and a mounting block (140) having a mounting portion configured to be coupled to a user of the prosthesis (100), an attachment portion and a gap portion (147), with the mounting block (140) attached to the first plate (130) at the attachment portion with a gap (147) between the mounting block gap portion (147) and the first plate (130). Also included is a resilient element (150) positioned at least partially within the gap (147), the resilient element (150) configured generally to dissipate stress in the first plate (130) and control deflection between the first plate (130) and the mounting block (140). The mounting block (140) may be substantially rigid with the area of the first plate (130) attached to the mounting block (140) becoming substantially rigid while the remainder of the first plate (130) is at least partially flexible. The resilient element (150) may be interchangeable to adjust performance of the prosthesis (100).

MULTI-AXIAL FITTING WITH SHOCK ABSORPTION FOR PROSTHETIC FOOT
A fitting (200) for a prosthetic foot permits multi-axial movement of the prosthetic foot with respect to a lower limb prosthesis and provides shock absorption. The multi-axial fitting (200) has a mount (210), a base (230), and a shock absorbing resilient member (250) disposed between the mount (210) and the base (230). The resilient member (250) is torqueable and compressible under force, providing shock absorption, rotation, medial lateral movement and dorsiflexion of the prosthetic foot with respect to the lower limb prosthesis.
