Open the CIPO recordAbstract From the Canadian patent
A dilatation balloon catheter (10) includes a shaft (12) having a proximal outer tube section and a distal outer tube section. The proximal outer tube section (40) is formed from a tubular braid of a stainless steel member, which is encased in a polymer material such as polyimide. The pick count of the braid may be increased along the proximal outer tube section toward its distal end in order to increase flexibility. The distal outer tube section (42) is a tube made of a polymer material, such as a high density polyethylene.

Why it's free to use
- Filed April 9, 1993 and granted March 27, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 9, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 9, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
