A patient support device, particularly a cane includes a fifth leg that extends outwardly from a central portion of a base assembly at a region intermediate the first, second, third, and fourth legs. The fifth leg provides increased balance and stability for the user. Moreover the base assembly includes a one-piece member constructed from a molded plastic composite material to reduce manufacturing costs. Additionally the fifth leg, is slightly recessed relative to the remaining four legs so that the patient's weight is evenly distributed to the perimeter of the support area defined by the base member.

Why it's free to use
- Filed June 27, 1997 and granted February 26, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 27, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 27, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
