The Rewalk robotic exoskeleton was developed by Dr. Amit Goffer. He is an Israeli inventor who became a quadriplegic after an ATV accident in 1997. Who better to invent something, than some one who knows first had what it is like to not walk. The system allows the user to sit up, stand, walk, climb stairs and the freedom to make their own decisions again.
Rewalk Robotics filed for an Initial Public offering to list on the Nasdaq back on July 10, 2014. They will offer 3,350,000 shares to the market at around 14 to 16 a share. This should help them raise around 60 million dollars off the IPO.
I have embedded two videos to describe your questions in more detail.
(1) The first video is the Introduction video on Rewalk Robotic website, which gives you the jist of it.
(2) The second video is footage of Barrack Obama visiting Rewalk Robotics on his trip to Israel back in 2013.
