Infusion treatment agents, catheters, filter devices, and occlusion devices, and use thereof
First Claim
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.

Abstract
Embodiments include an infusion-occlusion system having a delivery catheter, a guide catheter adapted to receive the delivery catheter, and a guidewire with an occlusion device adapted to be received within the guide catheter. The guide catheter of the catheter kit may be provided with an occlusion device at the distal end of the guide catheter. The delivery catheter may have an accessory lumen, coaxial or co-linear lumen, a supporting mandrel, or an occlusion device at its distal end. Moreover, according to some embodiments, occlusion devices may be a single material or a composite balloon having an inner liner and an outer layer of different materials, a high compliance low pressure balloon, or a filter device that restricts particles from passing through but does not restrict fluid, such as blood. An inflation device with a large volume and low volume syringe can be used to inflate the balloon.
