i-limb ultra

The i-limb ultra prosthetic hand is designed for those who want more from their prosthesis.

With the i-limb ultra, your prosthesis looks and moves like a natural hand. Motorized digits allow the hand to bend at the joints of each digit and individual stall out technology gives the hand a compliant grip so that the hand accurately conforms around the shape of the object being grasped.  

Utilizing its pulsing and vari-grip features, the i-limb ultra allows the user to increase the strength of their grip around an object. This can be very useful in situations where a firmer grasp is required, such as tying shoelaces tightly or opening a tightly closed jar of food.
