Prosthetic Technology

C-Leg, Genium & X3 Microprocessor Knee Unit

In 1999, the C-Leg microprocessor-controlled prosthetic knee revolutionized treatment for above‑knee amputees. Since it was introduced more than 40,000 people worldwide depend on its advanced technology every day. Whether they work as a police officer or at a desk, the modern C-Leg makes every step more secure. The most clinically evaluated microprocessor knee in history, C-Leg is backed by evidence showing the highest levels of safety, energy efficiency and cost effectiveness when compared to other prosthetic knees – making this technology the Standard of Care. In this advanced fourth generation C-Leg, people can speed up, slow down, take on hills and go down stairs step‑over‑step—all with a secure, comfortable stride.

The Genium maintains a hydraulically controlled 4˚ of preflexion of the knee joint when your heel starts your stride (“heel strike”), which allows your foot to reach full contact more quickly and gives you a more stable start to your step. Intelligent knee flexion (max. 17˚, depending on the situation) gives you more efficient, intuitive control of your prosthesis. The heart of the system: DSC continuously samples multiple environmental inputs—including a gyroscope and 2-axis accelerometer—which determine the appropriate resistance (support) and release at any time during your walking cycle. That means optimum security for you.You get precise control of your lower leg no matter what your walking speed is. This also helps to prevent falls.

Plié 3.0 Microprocessor Knee Unit

By integrating high-performance processing capabilities and a cutting-edge hydraulic system, the Plié 3.0 is the most responsive MPC knee ever developed. A finely tuned control system enables the Plié 3.0 to respond to ambulatory stimuli within 10 milliseconds. Consequently, users can stay in stance phase longer, take smaller steps and change walking speeds more fluidly. A proprietary position sensor and patent-pending load cell built into the frame of the Plié 3.0 provide input to advanced algorithms utilized by the microprocessor to control stance and swing, and stumble recovery parameters. The hydraulic cylinder changes resistance in response to a highly reactive, solenoid-activated spool valve that opens and closes in 10 milliseconds. Resistance is controlled by pressure and position rather than speed.

Featuring a high-performance aluminum frame, the Plié 2.0 knee exceeds ISO standards for structural integrity. In addition, its electronic components are sealed for water resistance.And it is now available with multiple designer fairing options. These designer fairings replace the original black fairing, increase the aesthetic appeal of the product and bring your personal style to the Plié.

The Rheo Knee®

The world’s first microprocessor knee system to utilize the power of artificial intelligence, the RHEO KNEE remains the most adaptable solution of its kind. It is also surprisingly simple to use.
The silver gray impact-resistant shell is made of of high-resistance polyurethane, its shape reflecting the anatomy of the human knee and lower leg. A soft pad at the front improves sensation when kneeling.

Integrated within the design‘s distal end is a Bluetooth® module for wireless communication and setup processes, as well as a rechargeable Li-Ion battery, which provides 24-48 hours of continuous use, dependent on activities. A single-pin port and rotation-independent circular plug make recharging easy, while the tamper proof on/off switch prevents unintentional use of the device.

Thanks to its low build height (length), the RHEO KNEE can be fitted with a much wider range of prosthetic feet than any other microprocessor knee on the market.

The Proprio Foot

Delivering unprecedented physiological benefits, the design of the PROPRIO FOOT significantly reduces many of the compensatory movements that amputees often find themselves doing.

The core foot design is based on proven Flex-Foot® technology, which incorporates lightweight, yet very strong carbon fiber that is cured and layered in processes similiar to those used in the aerospace industry.

Motion analysis for the PROPRIO FOOT is built on the patented technology platform from Dynastream, leading experts in the research and development of proprioceptive, “smart” devices using inertial and wireless technology.

By recognizing even the subtlest changes in movement, the sensor technology in the PROPRIO FOOT enables an appropriate and immediate response to variations in ground surface and activity.
Terrain Logic™, the patented artificial intelligence (AI) that is the ‘brain’ of the device, helps to replace the function that the body’s central nervous system would normally play in processing information about changes occurring inside and outside the limb if it was still intact.

A high precision linear actuator receives commands in the form of signals via a control board, which contain precise instructions concerning when and how fast to move to achieve the best possible response to any situation.

I-Limb Hand Bionic Technology

With the I-LIMB ULTRA, your prosthesis looks and moves more like a natural hand than any other powered prosthetic hand. Each finger moves independently and bends at the natural joints so that it can accurately adapt to fit around the shape of the object you want to grasp.

Powered by Touch Bionics’ unique biosim software, the i-limb ultra is the most versatile prosthetic hand available, providing you with the ability to customize the hand for your daily needs.

Choose from a wide selection of automated grips and gestures to help you complete your daily tasks, such as index point for typing, precision pinch mode for gripping small objects or natural hand position for walking or while at rest.

Utilizing its pulsing and vari-grip features, the i-limb ultra is the only prosthetic hand with the ability to gradually increase the strength of its grip on an object. This can be very useful in situations where a firmer grasp is required, such as tying shoelaces tightly or holding a heavy bag more securely.
