Open the CIPO recordAbstract From the Canadian patent
Synthetic surfaces such as surfaces of implantable prosthetic devices are modified to enhance their ability to support the growth, migration and attachment of epithelial cells. A surface modifier composition is covalently bound to the synthetic surface and an, epithelial cell-supporting coating is applied to the modified surface. The surface modifier composition may also include an epithelial cell-supporting material. The invention is particularly suited towards the modification of synthetic epikeratophakia lenses.

Why it's free to use
- Filed September 5, 1990 and granted July 30, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended September 5, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 5, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
