Technology is described to provide a locking device to control movement of a prosthetic limb. The technology may include a hydraulic damper having a movable damper wall in a hydraulic housing of the hydraulic damper, and the movable damper wall may form a first chamber and second chamber in the hydraulic damper. A first fluid channel may be coupled to the first chamber. In addition, a latch may be in fluid communication with the first fluid channel. A poppet valve can be configured to set the latch in an open position when pressure is reduced in the first chamber and to stop fluid movement when pressure is increased in the first chamber. A second fluid channel between the second chamber and the latch may enable fluid to flow between the second chamber and the latch.

Hydraulic locking device and systems

Technology is described to provide a foot and ankle prosthesis for individuals with lower limb loss. This technology is able to store and release energy and individuals or patients who are using the foot/ankle prosthesis may be able to expend less energy when walking. The system includes a hydraulic damper attached to dynamic energy storing spring elements. The axis of rotation of the system can be near to that of an intact human ankle, providing biomimetic function. The system can utilize spring elements based on the vertical displacement of the center of pressure of an intact normal foot. A hydraulic system can provide user adjustable heel height and adaptation to inclines. The dorsiflexion and plantar flexion resistances can be independently adjusted manually or electrically. In addition, the system can be automatically locked in dorsiflexion when loaded and unlock when unloaded.

Prosthetic foot/ankle system with automatic alignment

Technology is described to provide a powered prosthetic wrist flexion device or elbow device. This device helps individuals with upper-limb loss to orient and position grasped objects.

Powered prosthetic flexion device

An anchoring apparatus for locating a flexible tube or cord at a selected location between a fixed terminal and a movable device attached to one end of the tube or cord is disclosed. The apparatus includes a base having a securing clip extending from a circular platform, and a cover attached to the base and including a circular cover body and a raised shield section. A mounting material layer is affixed to a bottom surface of the base. A top portion of the shield section has an access opening thereacross extending between support openings at first and second side walls of the shield section. The tube or cord is releasably received at the clip through the access opening and support openings and is cooperatively held at a position relative to the base by the clip and the support openings.
