Open the CIPO recordAbstract From the Canadian patent
The stabilizing device can be adapted to an anchor such as a hook (1) of the usual shape with a hook body (4) and an incurved lug (7). The device comprises a stabilizing staple fastener (3) comprising a body (21) and staple legs (22-25). Said fastener body (21) is adapted so that the means for securing the hook (1) to an attachment rod (52) also attach the fastener (3) to the hook (1) by forcing back the legs (22-25) in the direction of the incurved lug (7) so as to pierce a portion of the vertebra located in the hollow of the hook (1). The hook (1) is thereby effectively stabilized on the vertebra.

Why it's free to use
- Filed April 19, 1995 and granted February 9, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 19, 2015.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 19, 2017.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
