  Loewen Prosthetic Advances in Technology

Advances in technology for prosthetic devices are happening almost daily. Technology such as the C-LEG© and other Micro Processor Controlled Knee Joints offer the closest possible approximation to natural gait for the above knee amputee providing stability and freedom. The I-LIMB Hand, is a first-to-market prosthetic device with five individually powered digits. This replacement hand looks and acts like a real human hand and represents a generational advance in bionics and patient care. Loewen Prosthetics is committed to keeping up with trends in technology to provide our patients with the absolute best prosthetic devices available to them.

C-Leg©... A New Dimension in Amputee Mobility
The world's first completely microprocessor controlled prosthetic knee joint means it's no longer necessary for an amputee to concentrate on the  task of walking.

Walk with confidence
The C-Leg© with an electronically controlled hydraulic cylinder is a quantum step forward in lower limb prosthetic technology.  It offers the closest possible approximation to natural gait.  This is the world's first completely microprocessor controlled prosthetic knee joint.  On-board electronic sensors collect real-time data to control stance and swing phase movements of the knee.

The C-Leg© meets the full range of stability and functional needs for today's amputee.  Advanced microprocessor control means it is no longer necessary to concentrate on the task of walking.  Individual adjustments are optimized during the fitting by interfacing the knee with a personal computer.

Electronic precision: Precise control
Providing optimal stability during all phases of gait was the highest priority during development of the C-Leg© .  Unique software algorithms determine the phase of the gait cycle being under taken and immediately adjust the knee functions to compensate.
During a typical 1.2 second gait cycle, the C-Leg© monitors information from multiple sensors more than 60 times.  The knee angle sensor provides data for dynamic control of swing phase, based on the step length and frequency.  Force sensors in the shin use heel and toe loading data to determine stance phase stability.

As a result, movement is easier and more natural.  Including walking down a ramp, stairs, or on uneven terrain.  By adjusting automatically to such conditions, the C-Leg© reduces the need to compensate with the opposite limb.

The I-LIMB Hand
The worlds first fully articulating and commercially available bionic hand.
Touch Bionics is a leading developer of advanced upper-limb prosthetics (ULP). One of the two products now commercially available from the company, the I-LIMB Hand, is a first-to-market prosthetic device with five individually powered digits. This replacement hand looks and acts like a real human hand and represents a generational advance in bionics and patient care.

The Touch Bionics I-LIMB Hand was developed using leading-edge mechanical engineering techniques and is manufactured using high-strength plastics. The result is a next-generation prosthetic device that is lightweight, robust and highly appealing to both patients and healthcare professionals.

The I-LIMB Hand is controlled by a unique, highly intuitive control system that uses a traditional two-input myoelectric (muscle signal) to open and close the hand’s life-like fingers. Myoelectric controls utilize the electrical signal generated by the muscles in the remaining portion of the patient’s limb. This signal is picked up by electrodes that sit on the surface of the skin. Existing users of basic myoelectric prosthetic hands are able to quickly adapt to the system and can master the device’s new functionality within minutes. For new patients, the I-LIMB Hand offers a prosthetic solution that has never before been available.

Advanced Design
The modular construction of the I-LIMB Hand means that each individually powered finger can be quickly removed by simply removing one screw. This means that a prosthetist can easily swap out fingers that require servicing and patients can return to their everyday lives after a short clinic visit. Traditional devices would have to be returned to the manufacturer, often leaving the patient without a hand for many weeks..
