Open the CIPO recordAbstract From the Canadian patent
The invention relates generally to medical devices and methods for reducing the intraocular pressure in an animal eye and more particularly, to stent type devices for permitting aqueous outflow from the eye's anterior chamber and associated methods thereof for the treatment of glaucoma. Some aspects provide a self-trephining glaucoma stent and methods thereof which advantageously allow for a 'one-step' procedure in which the incision and placement of the stent are accomplished by a single device and operation. This desirably allows for a faster safer, and less expensive surgical procedure.

Why it's free to use
- Filed April 8, 2002 and granted June 17, 2014. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 8, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 8, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
