Abstract
A method is provided including introducing a delivery device through a vessel wall to a treatment site within one of a peri-adventitial space or a pericardium adjacent a coronary blood vessel and delivering a treatment agent through the delivery device. The treatment agent is delivered through the delivery device according to conditions that hydraulically dissect tissue planes within the peri-adventitial space. A kit is provided including a delivery device having a needle to be advanced through one of an epicardium of a heart and a wall of a coronary blood vessel into a peri-adventitial space and a treatment agent comprising particles having an average diameter on the order of 15 microns or more to be delivered through the delivery device into the peri-adventitial space.
