Open the CIPO recordAbstract From the Canadian patent
Clot disruption and dissolution are achieved using a catheter (12) having both an agitator (30) and the ability to deliver a thrombolytic agent. The catheter (12) is introduced to a target region with a blood vessel and the agitator (30) manipulated to engage and disrupt a region of clot therein. The thrombolytic agent, such as tPA, streptokinase or urokinase, is directly , released into the clot at the point where the agitator (30) is engaging the clot. In this way, the thrombolytic activity of the agent is enhanced and the dissolution of the clot is improved.

Why it's free to use
- Filed January 24, 2001 and granted December 13, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 24, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 24, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
