Meridium – balanced stability

Hans walks down a path in the forest with his Meridium prosthetic foot.

Ascending and descending slopes

Real-time sensing of the ankle motions and slopes allows you to master ground inclinations effortlessly from the very first step. Increased security thanks to more ground clearance when ascending, comfortable descending thanks to the adapted rollover and fast full-surface ground contact.

Going down stairs

The Meridium lets you place your entire foot on the step as you go down stairs. Instead of thinking about positioning your foot correctly, you can concentrate on your surroundings.

Stable standing

The Meridium intuitively identifies when you are no longer moving and require a secure, stable stance – even on slopes or uneven terrain.

The Meridium prosthetic foot lowers itself to the floor when sitting.

Relief when sitting

When sitting, the Meridium prosthetic foot lowers itself to the floor, which achieves a more natural-looking foot position and can also help relieve your residual limb.

Hans changes from bare feet to leather shoes with his Meridium prosthetic foot.

Automatic heel height adjustment

Whether you are barefoot or wearing flat soles or heels – thanks to automatic heel height adjustment, shoes can be changed quickly and easily with the Meridium prosthetic foot.

The Cockpit app – easy mobile control

The Meridium adjusts itself automatically to diverse situations. You can easily adjust the Meridium via a smartphone using the convenient Cockpit app for iOS and Android devices. The app can be used to change the heel height, for example, or to select from a range of preset MyModes. The app also displays additional information such as the charge level of your mechatronic prosthetic foot.

User Experience

Moving ahead with confidence

Hans

Hans has many talents, but this is the first time he’s been able to make the most of his abilities. Whether playing an instrument, drawing or helping to decorate his new home, Hans loves being in the middle of the action. He wears the Meridium prosthetic foot – but it’s hardly noticeable to him or those around him.

Functionality

Stride adjustment in real time

1) Resistance adjusts when the foot touches the floor to achieve comfortable heel leverage that matches the your stride length.

2) Based on the individually adjusted resistance, the speed of plantar flexion immediately adapts to the gait situation with every step.

3) Thanks to the high degree of mobility and real-time adjustment during rollover, you benefit from prolonged, full-surface contact with the ground for the greatest possible stability and excellent traction.

4) The movable toe plate provides a large contact surface and ensures uniform pressure distribution in the forefoot area when rolling over the toes. The Meridium’s four axis design gives you a smoother, more natural gait pattern when rolling over the foot.

5) When your foot lifts from the floor, it remains in a rolled over position offering an enhanced level of safety as you walk.

FAQS

Answers for you

If the Meridium vibrates during use, this means there is an error. Vibrations at five-second intervals indicate overheating of the hydraulics, which may occur during continuous increased activity (such as walking downhill for an extended period). Please stop your activity immediately and allow the hydraulics to cool down until the vibration stops. Full activity may be resumed after the vibration stops.
