Clot disruption and dissolution are achieved using a catheter having both an agitator and the , ability to deliver a thrombolytic agent. The catheter is introduced to a target region with a blood , vessel and the agitator 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 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 November 25, 2014. 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.
