Open the CIPO recordAbstract From the Canadian patent
A system for measuring pressure in the body comprising an implanted device for detecting internal absolute pressure, an external monitor providing barometric (atmospheric) pressure, an acoustic or radio telemetric system and a global positioning system (GPS). The barometric pressure is retrieved from a remote source such as an Internet weather web site or a database containing real-time barometric pressure data for various locations in the world by using the GPS data. The gauge pressure is then derived by subtracting the barometric pressure from the absolute pressure.

Why it's free to use
- Filed May 3, 2003 and granted October 16, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 3, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 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.
