A self-adjusting adapter for a prosthetic leg having a foot and a leg socket has a low stiffness spring having a central opening, a high stiffness spring that has a central opening and is adjacent the low stiffness spring, a shaft or a bolt passing through the central opening in the low stiffness spring and the central opening in the high stiffness spring and a spring stiffener configured and positioned to restrain movement of the high stiffness spring relative to the low stiffness spring in a direction parallel to the low-stiffness spring. A connector for attaching the adapter to a leg socket is connected to the bolt or shaft and is capable of pivoting about an axis through the bolt or shaft. The adapter can be used an add-on component for existing prosthetic legs, or it can be integrated with foot design for the ankle-foot product category.

A vertical suspension system for a prosthetic foot includes a first member operatively coupleable to an amputee's residual leg. The suspension system can also include a second member coupleable to a prosthetic foot. One or more upper leaf springs and one or more lower leaf springs extend between and are attached to the first and second members such that at least one of the ends of each leaf spring is rotationally fixed to the first or second members, where the upper an lower leaf springs are spaced apart from each other.

Prosthetic feet that provide improved rollover and performance are provided. A prosthetic foot can include a lower foot member extending from a heel end to a toe end, a second foot member disposed above the lower foot member, and an optional third foot member disposed above the second foot member. The second foot member is tapered such that its thickness decreases toward the proximal end. Optionally, the second foot member can taper toward its distal end as well as toward its proximal end from an intermediate location on the second foot member. The third foot member can be tapered such that its thickness decreases toward the distal end. There can be a gap between a distal end of the third foot member and the second foot member that closes during dorsiflexion of the prosthetic foot during use and provides dynamic stiffness control to the prosthetic foot.

A pet prosthetic for a stump of an animal including: a clamp portion configured to clamp to an upper portion of the stump above an elbow joint of the animal or a knee joint of the animal; a stump holder configured to receive the lower portion of the stump below the elbow joint of the animal or the knee joint of the animal; a stump holder cradle configured to receive and support the stump holder; a left rear support operably connecting the clamp portion to the stump holder cradle; a right rear support operably connecting the clamp portion to the stump holder cradle; an ankle joint operably connected to the stump holder cradle; a left forward support operably connecting the clamp portion to the ankle joint; a right forward support operably connecting the clamp portion to the ankle joint; and an artificial paw operably connected to the ankle joint.

Disclosed herein are systems and methods for determining alignment angles between a first prosthetic component and a second prosthetic component that are joinable together in a fixed orientation relative to each other, wherein the fixed orientation includes a first angle and optionally also a second angle that are perpendicular to each other, and wherein the first and/or second angles are selectable from a range of angles to provide a desired fixed orientation between the two prosthetic components. The system includes a magnet fixedly coupled to the first prosthetic component and one or more magnetic intensity sensors configured to be coupled to the second prosthetic component in a fixed orientation relative to the second prosthetic component such that the sensors are operable to sense a magnetic field of the magnet and produce an output signal in response to the strength of the sensed magnetic field. The system can include a processor operable to receive the output signals from the sensors and determine the first and/or second angles.

A prosthetic joint system for users comprising a housing having an interior cavity, a center axis in said interior cavity, and an attachment means for fixedly connecting said housing to said user; an inner cylinder disposed in said housing interior cavity wherein said inner cylinder rotates around said center axis of said housing; an appendage attached to said inner cylinder; a sensor system attached to said appendage; and a dampening system, having a power source, in communication with said sensor system, said inner cylinder, and said housing for controlling dampening of the rotation of said inner cylinder around said center axis of said housing.

A magnetic locking actuator for a prosthetic or orthotic device is provided. The actuator includes a first component including one or more magnets and a second component including one or more magnets. The first and second components are coupled to separate portions of the device. The magnets allow for adjustment of a length of the actuator to adjust an angular orientation of the first and second portions of the device. When magnets in the second component are aligned with magnets in the first component having an opposite polarity, a position of the second component is fixed relative to the first component, locking the actuator. When magnets in the second component are not aligned with magnets in the first component having the opposite polarity, the position of the second component is adjustable relative to the first component, thereby allowing adjustment of the height of the actuator.

A method for connecting at least two structural parts of an orthopedic component, wherein the structural parts are retained in an orienting device while oriented in relation to each other, and an intermediate space thus being formed between the structural parts. The orienting device and the structural parts together form a cavity, which has a flow connection to at least one feed connection, via which an adhesive for adhesively bonding the structural parts is introduced into the cavity.

A pet prosthetic for a stump of an animal including: a clamp portion configured to clamp to an upper portion of the stump above an elbow joint of the animal or a knee joint of the animal; a stump holder configured to receive the lower portion of the stump below the elbow joint of the animal or the knee joint of the animal; a stump holder cradle configured to receive and support the stump holder; a left rear support operably connecting the clamp portion to the stump holder cradle; a right rear support operably connecting the clamp portion to the stump holder cradle; an ankle joint operably connected to the stump holder cradle; a left forward support operably connecting the clamp portion to the ankle joint; a right forward support operably connecting the clamp portion to the ankle joint; and an artificial paw operably connected to the ankle joint.

A prosthetic device has a movable body and foot member with an end effector for contacting an external surface. A base body is coupled to a first joint of the foot member. A compliant linking member is disposed between a second joint of the foot member and a first joint of the moveable body. The compliant linking member can be a spring or flexible beam. A passive linking member is coupled between a third joint of the foot member and a third joint of the moveable body. An actuator is disposed between the base body and the second joint of the movable body. The actuator can be a motor with an extension member. The compliant linking member extends during roll-over phase. The actuator acts to assist with the extension of the compliant linking member during roll-over phase to aid with push-off phase in the gait cycle.
