Ekso Bionics Holdings Inc. has received a green light from the U.S. FDA to market its Eksonr robotic exoskeleton for use with patients with acquired brain injury (ABI). The company said it is the first exoskeleton product to receive the agency's nod for rehabilitation use with ABI, allowing a broader patient population to access the device. This is good news for Richmond, Calif.-based Ekso, which, like many other device companies, saw its earnings off during the first quarter.
