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.
