Prosthetics are outrageous, I can't imagine what eLegs cost.
Berkeley Bionics reveals eLEGS exoskeleton, aims to help paraplegics walk in 2011
Update: We just got to see the eLEGS walk across stage, and you'll find a gallery full of close-up pics immediately below. We also spoke to Berkeley Bionics CEO Eythor Bender, who detailed the system a bit more -- it's presently made of steel and carbon fiber with lithium-ion battery packs, weighs 45 pounds, and has enough juice to run for six hours of continuous walking. While he wouldn't give us an exact price, he said they're shooting for $100,000, and will be "very competitive" with other devices on the market. Following clinical trials, the exoskeleton will be available to select medical centers in July or August, though Bender also said the company's also working on a streamlined commercial version for all-day use, tentatively slated for 2013.
