Open the CIPO recordAbstract From the Canadian patent
A noninvasive system and method of measuring vascular pressure waveforms in a living being includes a tonometric sensor device that reduces or ideally, eliminates, distortion in the vascular pressure waveforms measured. The data from the vascular pressure, waveforms are manipulated to determine cardiovascular conditions of a living being based on, a comparison of measured augmentation index and/or pulse wave velocity values to typical, values for healthy living beings of similar physiological characteristics.

Why it's free to use
- Filed January 30, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended January 30, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 30, 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.
