Open the CIPO recordAbstract From the Canadian patent
A catheter introduction apparatus provides an optical assembly for emission of laser light energy. In one application the catheter and the optical assembly are introduced percutaneously and transseptally advanced to the ostium of a pulmonary vein. An anchoring balloon is expanded to position a mirror near the ostium of the pulmonary vein such that light energy is reflected and directed circumferentially around the ostium of the pulmonary vein when a laser light source is energized. A circumferential ablation lesion is thereby produced which effectively blocks electrical propagation between the pulmonary vein and the left atrium.

Why it's free to use
- Filed September 11, 2003 and granted March 20, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 11, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 11, 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.
