Open the CIPO recordAbstract From the Canadian patent
A stent is covered with a discontinuous expandable wall by the steps of radially contracting the stent and inserting at least a portion of the contracted stent into a tube, the inner surface of which has been previously done over with a lifting medium. The stent is allowed to radially expand in the tube, and the assembly tube plus stent is wetted with an elastomeric polymerisable composition dissolved in a sufficient amount of solvent to permit wet forming. After evaporation of the solvent the elastomeric composition, in the tube is polymerised and the layer covered portion of the stent is taken out of the tube.

Why it's free to use
- Filed February 3, 1994 and granted July 18, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended February 3, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 3, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
