Open the CIPO recordAbstract From the Canadian patent
An intraluminal catheter and stent delivery system using vibratory energy to open calcified lesions. The catheter having an expandable stent mounted on a balloon portion thereof, is adapted to convey vibratory energy through the stent to a calcified lesion to facilitate crossing and dilating the lesion during a PTCA procedure. A vibratory energy source is transmitted through a flexible wire to provide vibratory energy to the stent, which in turn provides vibratory energy to a calcified lesion to thereby at least partially pulverize the lesion and assist in crossing and dilating the body lumen.

Why it's free to use
- Filed January 29, 1997 and granted April 10, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 29, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 29, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
