  • inserting a first catheter into a body lumen adjacent to a plaque formation;

    inflating a balloon from the first catheter adjacent to the plaque formation, wherein the balloon has a proximal end and a distal end;

    inserting a second catheter adjacent to the first catheter, the second catheter having a distal end portion, a lumen, and at least one hole, the lumen being in fluid communication with the at least one hole;

    advancing the distal end portion of the second catheter distally along and in contact with an exterior surface of a balloon wall of the inflated balloon of the first catheter after the first catheter has been positioned adjacent to the plaque formation;

    advancing at least a portion of the second catheter distally into a subintimal space adjacent to the atherosclerotic plaque;

    removing the first catheter while maintaining the second catheter in the subintimal space;

    injecting a therapeutic agent into the subintimal space adjacent to the atherosclerotic plaque; and

    removing the second catheter;

    wherein the balloon wall includes an interior surface in fluid communication with an inflation lumen of the first catheter, and the exterior surface of the balloon wall is in fluid communication with fluid within the body lumen.
