    摘要: A system and method in accordance with the present invention provides a infusion catheter that is flexible, has such a smooth traction and a low profile to minimize break up of the obstruction when crossing it, can access distal vasculature quickly, is easy to use and readily to be implemented in the conventional PCI. Another object is to provide a method that can be performed within a short period of time and employs the catheter described herein to infuse a therapeutic agent distally to the obstruction before it is removed as a means of reducing reperfusion injury, protecting distal vasculature and microcirculation, preserving myocytes, reducing infarct size and ischemic damages in the heart, brain, lung, liver, kidney and limb. Another object is to provide complementary feature options to the infusion catheter and the aspiration catheter to improve the speed and quality of the vessel clearance.
