Prosthetic Technology


New Technologies

There are many prosthetic designs on the market today, with new technologies being released all the time. Choosing which of the countless options is the most clinically appropriate for your needs is a challenge that requires careful consultation with your prosthetist.

  • iLimb Ultra

    iLimb is an innovative myoelectric prosthetic hand that is used for both above and below elbow amputees. iLimb Ultra is controlled by muscular movements that are programmed to each user’s needs, taking the options for use far beyond the basic grasping capabilities offered by traditional myoelectric devices.

    The iLimb Ultra allows independent finger movements, offering grasping options that were never before possible. Amputees who are existing myoelectric users can benefit from the ability to live much more ambidextrously with iLimb Ultra. The use of the iLimb Ultra allows arm amputees to grasp balls, cups, and more delicate objects than a traditional myoelectric hand. There is an iPhone app included with the iLimb Ultra which allows for easy control of the arm settings for specific uses of the hand, like typing. The iLimb can also be finished with a custom painted glove, which offers a very life-like high resolution silicone cosmetic option.

    It is important to note that advanced myoelectric devices like the iLimb Ultra require significant medical justification and a clear clinical need to be established before submitting for insurance coverage. While Medical Center’s Prosthetics insurance team is highly skilled at appealing to insurance companies, many times these devices are not deemed to be medically necessary and are denied coverage. At this time, iLimb Ultra is not covered by Medicare.

  • Ossur Unity
    Ossur Unity240

    The Ossur Unity Vacuum System is a first-of-its-kind vacuum system that pulls the vacuum in the socket using the energy created by the natural motion of the prosthetic foot. The benefits of this are a lighter, quieter, simpler vacuum suspension than any other vacuum technology on the market. Currently, the Unity system is indicated for below knee amputees, and is designed to work with all Flex-Foot feet by Ossur. Learn more about the Unity System in our new prosthetic technology review.

  • Ossur XC Rotate

    The Vari-Flex XC Rotate by Ossur is an innovative new prosthetic foot that offers more dynamics and function in a lightweight and short build height. This is especially helpful for active amputees with long residual limbs, who have trouble fitting highly dynamic feet due to the lack of space. The XC Rotate borrows the design and energy return of Ossur’s Flex Run running foot, while incorporating benefits of a carbon fiber prosthetic heel and vertical and rotational dampening for high activity. 

  • LimbLogic Vacuum

    The Willow Wood LimbLogic system offers security and flexibility. This electronic elevated vacuum system will soon be available in a new and improved version featuring a small Bluetooth® low energy fob, inductive charging, and an improved controller design. The LimbLogic system continually monitors a socket’s vacuum level to maintain a secure fit. With the handheld fob, you are able to increase or decrease the vacuum level as desired. 

  • Ottobock Harmony Vacuum

    The Otto Bock Harmony vacuum offers a secure suspension by creating a negative vacuum in the socket, offering unprecedented comfort, control and safety. The system uses a pump and an exhaust valve, which are activated at every step when using the mechanical pump or by a sensor with the electronic version. The pump and valve allow the system to constantly regulate pressure for the optimal suspension. The mechanical version of the Harmony also offers a shock damping and torsion function, integrated into the mechanical pump.

  • Ottobock Genium Knee

    This innovative bionic knee features a state of the art microprocessor-controlled knee joint utilizes a complex sensory system and sophisticated rule sets to mimic natural gait more closely than any other prosthetic knee. The unique Genium technology by Otto Bock is not a next-generation C-Leg, but is a sophisticated new technology platform built to gather exponentially greater microprocessor inputs that result in very precise responses. It offers some never before seen special features to help users step over obstacles and ascend stairs.

    Wearers of the Genium are often able to ascend stairs step over step, and cross obstacles more smoothly. For the wearer, motion becomes intuitive. Barriers and obstacles become an unconscious part of life instead of an interruption. The Genium makes it all easier without risking stability. 

  • Ottobock Helix Hip

    The Otto Bock Helix Hip Joint System is suitable for hip disarticulation and hemipelvectomy patients. It offers patients maximum security and function for a wide range of everyday activities.

    Wearers will easily notice how easy it is to initiate swing phase with the hip joint’s integrated expansion springs. The energy stored during the stance phase is used during the swing phase initiation to compensate for the missing hip muscles and to reduce the amount of energy needed for walking. It also allows for a dampened, controlled heel strike in the stance phase with significantly reduced hyperlordosis as well as a natural hip joint extension. Therefore, the user can accomplish a more controlled, smooth roll-over on the prosthesis under full load. 

    The Otto Bock Helix Hip reduces the risk of users falling, improved posture while sitting, and also makes it easier to accomplish activities such as putting on shoes or getting in and out of car. 

  • iWalk BiOM

    By using robotics to replicate the calf muscles and Achilles tendon, the iWalk BiOM feels and functions like no other foot/ankle prosthesis. With each step, the iWalk BiOM provides a powered push-off which propels the wearer forward. It is the only prosthesis in the world that does not depend on the wearer’s energy. With the iWalk BiOM, users will experience natural walking mechanics and increased stability, mobility, and confidence.

    The iWalk BiOM affords amputees to walk with natural energy. Unlike other prosthetics, the iWalk BiOM requires less energy and walks with greater ease. The Mobility with the iWalk BiOM requires the same metabolic energy used by non-amputees which will also provide more power for you to walk faster. Patients will no longer feel like their prosthetic is holding them back. It delivers a natural gait at variable speeds like other prostheses have never been able to achieve. Amputees will feel a greater stability with the iWalk BiOM. Users are able to negotiate stairs and inclines with increased confidence and stability due to improved articulation and the design’s ability to mechanically yield and conform.

  • Ossur Symbionic Leg

    The first complete bionic leg, combining a powered ankle and an adaptive microprocessor knee joint. Featuring a specially designed and calibrated compbination of Ossur’s proven PROPRIO FOOT and RHEO knee technologies, the Symbionic Leg provides unmatched benefits for transfemoral amputees. The active toe lift in swing clears the ground and minimizes the risk of tripping; if a stumble should occur, an advanced stumble recovery feature protects the user from a fall by providing instant stance support. The Symbionic leg also adjusts the ankle angels according to terrain conditions and steepness of slope. This generates better ground contact and optimal knee response when ascending or descending ramps for users. The heel adjustment also makes changing shoes or going barefoot simple without compromising the alignment of the prosthesis. 

  • Ossur Proprio Foot

    Featuring sensors and motors that allow the foot to adapt to even the subtlest changes in movement, PROPRIO FOOT enables an appropriate and immediate response to changes in ground surface and activity. Users are able to easily transition to different walking terrains. Terrain Logic,  the patented artificial intelligence is the ‘brain’ of the device, and helps to replace the functions 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.  

    The Proprio Foot works in a continuous cycle; at its first sense of mobility,  it repeatedly analyzes movements it in order to calculate and then direct an appropriate response. The prosthetic acts upon this information and with its precision motor generates movements performed previously by muscles. With each step, users will regain mobility and confidence with use of the Proprio Foot.

  • Ossur Power Knee

    The Power Knee combines power, safety, and endurance in its unprecedented function and performance. It is the world’s first and only active prosthesis for above-knee amputees, this highly intelligent knee works as an integrated extension of the user, replacing true muscle activity to bend and straighten the knee as required. Users are able to transition walking speeds and take on inclines with the Power Knee’s unique patterns of gait for natural, efficient motion.

  • ottobock Kids Hook
    ottobock kids hook

    A hook can be used as a terminal device instead of  hand. Hooks are especially good for activities that demand precision for grasping small objects such as screws or nails. The hook is a reliable and robust tool which can keep up with the lifestyle of a child. Hooks are opened via a body harness worn on the upper body. They close independently by means of spring or elastic components. While not necessarily new, they remain a great, high-functioning upper-extremity prosthetic option.
