Open the CIPO recordAbstract From the Canadian patent
The invention comprises a massage device consisting of a hollow bell-shaped body with a lip around the lower opening. The body has an inner wall extending to the lip so as to create two isolated chambers both of which are connected to a pump that generates a desired pressure gradient between them creating a wave effect comparable to the massaging action hitherto applied manually in kinesitherapy.

Why it's free to use
- Filed April 2, 1997 and granted February 1, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 2, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 2, 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.
