Open the CIPO recordAbstract From the Canadian patent
A probe such as an endoscope equipped with a biopsy needle is guided to a target in or adjacent to the respiratory system. The position of the probe is monitored. A representation of the probe is superimposed on a previously acquired image of the respiratory system and adjacent tissues. Artifacts caused by motion due to respiration are suppressed by monitoring the respiratory state of the patient, and acquiring the probe position when the respiratory state of the patient is equal to the respiratory state of the patient during image capture.

Why it's free to use
- Filed February 25, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 25, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 25, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
