OrthoCor Medical: Trying to get a leg up

Using magnetism and heat, OrthoCor Medical's device is designed to provide help for battered knees.
Located in the University Enterprise Laboratories business incubator in St. Paul, the tiny three-person firm is on the cusp of rolling out its core (and so far, its only) product -- a unique knee brace that, according to the company, provides temporary relief of joint pain and arthritis and, longer term, reduces swelling and pain.
