Abstract: A negative pressure wound therapy (NPWT) orthopedic device includes a base shell and a dorsal shell contoured to generally correspond to an opening of the base shell. The dorsal shell includes a proximal section and a distal section. The proximal section at least in part defines a receiving space. A NPWT system includes a pump mechanism secured in the receiving space and a wound covering situated inside of the base shell and arranged to form a sealed volume over a wound area of a user. At least one conduit forms a fluid connection between the wound covering and the pump mechanism. The pump mechanism is arranged to apply a negative pressure to the wound area through the at least one conduit.

Abstract: A system and method associated with the movement of a limb. In one example, the system, such as a prosthetic or orthotic system, includes an actuator that actively controls, or adjusts, the angle between a foot unit and a lower limb member. The actuator preferably selectively locks during a desired phase in a gait cycle of the limb and minimizes friction against a rotor of the actuator. A processing module may control movement of the actuator based on data obtained from a sensor module. For instance, sensing module data may include information relating to the gait of a user and may be used to adjust the foot unit to substantially mimic the movement of a natural, healthy ankle. The system may further accommodate, for example, level ground walking, traveling up/down stairs, traveling up/down sloped surfaces, and various other user movements. In addition, the processing module may receive user input or display output signals through an external interface.

Abstract: A polycentric hinge for an orthopedic device includes first and second hinge arms, and two cover plates, rather than numerous individual parts and fasteners. The first and second cover plates define a plurality of bearings and a plurality of recesses for receiving the bearings, whereby the hinge arms are mounted about the bearings and are pivotable relative to one another while encased by the first and second cover plates.

Abstract: An ankle module for a prosthetic foot can have an adapter portion pivotally coupled to a base portion. The base portion can be coupled to the prosthetic foot. The adapter portion can have a coupling member that removably couples the prosthetic foot to a prosthetic pylon or socket. The adapter portion can also have cylinders housing pistons slidably displaceable within the cylinders. An actuator is selectively actuatable to place the cylinders in fluid communication, allowing a fluid to flow between the cylinders as an angular position of the adapter portion is adjusted relative to the base portion, thereby adjusting the dorsi-plantar position between the adapter portion and the base portion of the ankle module. The actuator can be selectively actuatable to fluidly isolate the cylinders from each other so that the angular position of the adapter portion relative to the base portion remains substantially fixed.

Abstract: An orthopedic device includes a base shell having ankle and foot receiving portions. The base shell forms an opening over a dorsal aspect of the base shell. A dorsal shell is contoured to generally correspond to the opening in the base shell. At least one tightening member is connectable to the base shell and extendable over the dorsal shell to secure the base and dorsal shells together about a user's lower leg and foot. At least one inflatable bladder is provided in the ankle receiving portion of the base shell. A pump assembly is arranged to inflate the at least one inflatable bladder. The pump assembly is situated on the at least one tightening member such that the position of the pump assembly is substantially fixed relative to the base shell as a user walks in the orthopedic device.

Abstract: An orthopedic device has first and second elongate struts each having a strap coupling member, and a flexible strap securing to the first and second struts by the strap coupling members. The orthopedic device includes various embodiments of hinge assemblies including flexion and extension stops and locks for maintaining the hinge assembly in a fixed configuration. The orthopedic device has various embodiments of strap assemblies for securing components to cuff assemblies.

Abstract: A dynamic tension system connects to an orthopedic device having a frame and a hinge connected to the frame. The dynamic tension system includes a cable, an adjustment mechanism connected to the cable and arranged to incrementally wind or release the cable, and a tension control device connected to the adjustment mechanism and arranged to limit the adjustment mechanism from winding of the cable past a predetermined tension level.

Abstract: A prosthetic adapter including a lower connector, an upper connector rotatably coupled to the lower connector, and a locking mechanism for preventing the upper connector from rotating relative to the lower connector. The locking mechanism is arranged to generally automatically retain a locked position when the lower connector is rotated to an original, predetermined alignment. An activation member is connected to and arranged for operating the locking mechanism.
