Genium X3

Reclaim all you want to be.

The Genium X3 has now been developed even further for smoother, more intuitive walking, improved safety, and better support in everyday situations. Additionally, the Genium X3 is simple to control using the Cockpit app on your iPhone or Android smartphone.

Building on the unique functionality of the Genium leg prosthesis, the Genium X3 is particularly robust and resilient. Physically demanding occupations, an active family life, swimming and sports activities, and situations where you encounter water, dust, sand, dirt, or grime – these are the ideal conditions for the Genium X3.

Highly natural

Thanks to intelligent sensor technology, the Genium X3 responds reliably – in real time. As a result, it lets you change walking speeds, use stairs step-over-step, overcome obstacles safely, stand in a relaxed position on inclines, and walk backwards.

Water? No problem

The Genium X3 lets you shower, swim, or work in damp conditions without thinking twice. Special materials, coatings, and components protect the electronics. The joint is waterproof (even when exposed to strong jets of water) and corrosion-resistant.

Custom modes

Want to configure your leg prosthesis for activities you do frequently? Thanks to the large selection of MyModes Plus, you and your technician can easily set up to five pre-settings for work, recreation, and sports. These can be selected using the app or a movement pattern.

Moving at high speed

Whether you’re running to catch the bus or keeping up with your kids, the walk-to-run function lets you change speeds spontaneously for short sprints. An additional running mode for longer distances was developed especially for sports activities with the Genium X3.

Custom configurations with MyModes

Unique technology at the heart of your mobility

Movement is calculated with incomparable accuracy and initiated in real time by the Genium X3, whether on uneven terrain and slopes, when changing speeds, or in confined spaces. Studies prove that providing targeted relief for the contralateral side also has long-term health benefits. Particularly robust materials allow even more freedom of movement, including in wet and harsh environments. Patients can benefit from focusing their attention on the important things in life, rather than having to think about every step.

Smart adjustment options via app

It’s all in your hands. Thanks to integrated Bluetooth, the Genium X3 can be configured using an app. This makes it very easy to select additional movement patterns, which are stored by your technician as MyModes. Switch the joint to mute mode when you're at the movies or the theater. You can also read the battery charge level with the Cockpit app. The Genium X3 can be configured with the Cockpit app for Android was well as Apple (iOS) devices.

With the market launch of the Genium leg prosthesis in 2011, Ottobock opened up entirely new horizons for prosthesis wearers: an unprecedented, natural gait pattern, climbing stairs step-over-step, overcoming obstacles, walking backwards, relaxed standing – to name just a few. For the first time, people with a transfemoral amputation experienced a range of new functions that provided perfect support for their desire to live a more active and independent everyday life.

Based on human movement as the model, the Genium has been developed even further. The result is a noticeably smoother gait and even better support and safety in everyday situations, for instance on ramps, in confined spaces, or when changing walking speeds.
