Open the CIPO recordAbstract From the Canadian patent
The system assesses the endothelial function of a subject. Particularly peripheral tissue perfusion measurements taken in a subject are compared to reference perfusion data and the comparison yields an assessment of endothelial function. The reference may be data indicative of peripheral tissue perfusion in a healthy person. Also peripheral tissue perfusion , measurements taken in a subject when perfusion is in an unperturbed state (the reference) can be compared to perfusion measurements taken promptly after a challenge to the normal or unperturbed tissue perfusion of the subject.

Why it's free to use
- Filed April 3, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 3, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 3, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
