A method for treating an obstruction of a microvascular vessel within a patient, comprising:
- advancing a distal end of a guidewire to a location in communication with said obstruction;
- advancing a distal end of a treatment catheter over said guidewire to said location in communication with said obstruction;
- releasing a treatment agent from said treatment catheter;
