Embodiment Construction
[0019] figure 1 A catheter system 2 according to one embodiment of the invention is shown. As will be described in detail herein, catheter system 2 is used to provide pressurized fluid (eg, thrombolytic drugs) at multiple sites for removal or destruction of thrombi from blood vessels, such as arteries or veins. By providing direct delivery of pressurized fluid along multiple sites, the pressurized fluid penetrates the clot more efficiently and reduces procedure time compared to other methods. In one example, thrombolytic drugs delivered to blood vessels include, but are not limited to, cytolytic drugs (e.g., tissue plasminogen activator (tPA)), or other agents that interact with and actively reduce thrombus size (e.g., , destroy, remove, minimize or eliminate) drugs. In some instances, after catheter system 2 delivers cytolytic or other drugs to actively reduce the size of the thrombus, a thrombectomy catheter is used to further macerate and aspirate any remaining thrombus ...
