VALENCIA, Calif., May 10, 2011 /PRNewswire/ -- Bioness Inc. today announced that it has received 510(k) clearance from the U.S. Food and Drug Administration (FDA) for its NESS L300® Plus System. The device combines the Company's NESS L300® Foot Drop System with a thigh stimulation cuff, to provide knee flexion and extension in addition to ankle dorsiflexion during gait. The NESS L300 Plus is intended for persons with upper motor neuron injury or disease resulting from stroke, multiple sclerosis, traumatic brain injury and spinal cord injury. The device also may facilitate muscle re-education, prevent/retard muscle atrophy, maintain or increase range of motion and increase local blood flow.

The addition of the thigh stimulation cuff, synchronized with a wireless heel sensor to detect when the foot is on or off the ground, controls the knee, making it easier to walk. Historically, patients have relied on rigid plastic braces which restrict thigh and ankle movements and can lead to additional problems, including increased falls.
