Open the CIPO recordAbstract From the Canadian patent
A replacement heart valve assembly includes an intravascular radially expandable stent and a biological valve which is secured to the stent. The stent/valve assembly is positioned onto the inflatable portion of a balloon catheter, and percutaneously implanted into a body lumen. The stent is made from a highly, malleable material which allows localized plastic deformation and further allows, subsequent radial reexpansion of the stent/valve assembly as needed. The biological, valve is, for example, a harvested bovine jugular valve which can be adapted for use, as a replacement for a malfunctioning human pulmonary valve.

Why it's free to use
- Filed February 1, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 1, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 1, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
