Open the CIPO recordAbstract From the Canadian patent
The current invention is a comparatively thick-walled vascular stent comprising sets of strut members connected by flexible links. This design uses a script "N" shaped flexible link. The "N" links are designed to nest one into the other, allowing the stent to be both thick-walled and to crimp down without overlap onto a low profile balloon. The "N" links are attached to the strut members off center near the end of the curved end strut portion of each strut member. This off center attachment point allows for a more flexible link without increasing the cell size of the expanded stent. The "N' links maintain a width to thickness ratio of at least 1.5 to one.

Why it's free to use
- Filed August 10, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 10, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 10, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
