Smart Control

High / Low


i-Limb Wrist

The first integrated hand and wrist prosthesis with synchronized rotation and grip selection.

When the prosthesis is held horizontally and a grip is activated using any of the control options of the i-Limb Ultra hand, the i-Limb Wrist will automatically rotate to the predefined rotation for that grip.

The i-Limb Wrist offers simultaneous rotation and direct rotational control.

Simultaneous rotation - when accessing a grip through any control option on the i-Limb Ultra hand the i-Limb Wrist will automatically and simultaneously rotate to the pre-set rotation for that grip.

Direct rotation – the wrist can be directly rotated without changing grip, using SMART control.

SMART control is calibrated during set up of the prosthesis to the individual users unique muscle activities. Traditional control methods of co-contraction or high/low are also available.

Key Features:

  • Set up and calibration via Biosim on iPad.
  • 2 way communication between i-Limb Ultra and i-Limb Wrist allows simultaneous rotation upon grip selection.
  • Expansion ring for assembly and disassembly into prosthesis.
  • Utilises digital electrodes for optimal control.
  • 50/60Hz switchable via Biosim and My i-Limb App.
  • 2 year warranty.

App control

Quick Grips provide instant access to 12 pre-programmed grips, allowing huge versatility and flexibility in customizing the hand for a variety of daily activities.

Muscle Control

Triggers are specific muscle signals that are used to instruct the i-Limb Ultra to activate a specific grip.
