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.
