1. A method comprising:

  • accessing a vessel selected from the group consisting of external femoral, interior femoral, carotid, jugular, brachial, subclavian, or cephalic with a guide catheter;

    thenaccessing a coronary sinus with the guide catheter;

    thenfeeding a retroinfusion balloon catheter and a guidewire with an occlusion device at a distal end of the guidewire to the coronary sinus, great cardiac vein, posterior vein of left ventricle, middle cardiac vein, small cardiac vein, or anterior cardiac vein of right ventricle through a lumen of the guide catheter;

    thenperforming a venogram, wherein performing the venogram comprises injecting a dye into and visualizing one or more target vessels;

    thendeploying the guidewire and the balloon catheter to the one or more targeted vessels, wherein deploying comprises advancing the guidewire into the one or more target vessels, and then threading the balloon catheter over the guidewire to the one or more target vessels;

    thenmeasuring a baseline parameter in a vein adjacent to a distal end of the balloon catheter, wherein the baseline parameter comprises one of pressure, flow, oxygen saturation, pH, or temperature;

    theninflating a balloon at the distal end of the balloon catheter and engaging the occlusion device at the distal end of the guidewire, wherein inflating the balloon is sufficient to make a pressure waveform in the vein become ventricularized;

    after inflating the balloon and after engaging the occlusion device, delivering a liquid comprising at least one of a drug and a treatment agent through the balloon catheter to an outlet port on the balloon catheter distal to the balloon and proximal to the occlusion device; and

    thenperforming an infusate-uptake-enhancing procedure, wherein the infusate-uptake-enhancing procedure is one of electroporation, ultrasonic excitation, or photodynamic therapy.
