Slideshow: Top Medical Tech Engineering Innovations

March 30, 2012

Physicians get the credit for saving lives, but the behind-the-scenes work of engineers improves the lives of countless people in hospitals across the country every day.

Bionic limbs, innovative infusion systems, and transcranial doppler brain scanners are just some of the innovations engineers are bringing to the exploding medical design arena.

Jesse Sullivan, a Tennessee power company lineman whose arms were amputated after he was electrocuted on the job, now has artificial limbs that let him rotate his wrists and upper arms, bend his elbow, grip with his hand, and, incredibly, feel. Sullivan's arm employs nerves from the chest muscle. When that muscle contracts, a myoelectric sensor atop his skin detects the contraction and sends it to an amplifier and then to a digital signal processor (DSP) in the Boston Digital Arm. The arm’s DSP interprets the signal and then sends a command
to the hand motor, which closes the hand.
