FDA approves Deka Arm System prosthetic limb-DEKA Integrated Solutions

The FDA on 9 May 2014 allowed marketing of the DEKA Arm System from DEKA Integrated Solutions being the first prosthetic arm that can perform multiple, simultaneous powered movements controlled by electrical signals from electromyogram (EMG) electrodes. EMG electrodes detect electrical activity caused by the contraction of muscles close to where the prosthesis is attached. The electrodes send the electrical signals to a computer processor in the prosthesis that translates them to a specific movement or movements.

The EMG electrodes in the DEKA Arm System convert electrical signals into up to 10 powered movements, and it is the same shape and weight as an adult arm. In addition to the EMG electrodes, the DEKA Arm System contains a combination of mechanisms including switches, movement sensors, and force sensors that cause the prosthesis to move.

This prosthetic limb system can pick up objects as delicate as a grape, as well be able to handle very rugged tools like a hand drill.
