Regional cardiac tissue treatment

摘要

A method for treating an occlusion in a coronary artery of a patient includes percutaneously advancing an occlusion treatment tool (such as an angioplasty balloon or stent delivery device) through the vasculature of the patient and into a coronary artery to a site of the occlusion. Following the treatment of the occlusion, a therapeutic agent is admitted into the first coronary artery. The therapeutic agent is selected to treat microvasculature obstructions at a target cardiac tissue site distal to the site of the occlusion.
