A catheter for collecting fluid such as blood from a vessel such as a coronary sinus of a patient has an elongated, flexible tubular portion and an annular sealing member spaced from a distal end of the tubular member. A proximal end of the tubular member is adapted to be connected to a source of suction for applying suction to a collection lumen of the tubular member. The distal end is placed in a blood vessel with the sealing member spaced from opposing surface of the vessel in an absence of a suction applied to the collection lumen. Suction is applied to the collection lumen in an amount sufficient to draw blood from the vessel through the fluid inlet and into the collection lumen and further sufficient to urge the opposing surface of the vessel to migrate into sealing engagement with the sealing member.

APPARATUS FOR VISUALIZATION OF CORONARY VEIN PROCEDURE
Visualization of a medical procedure to be performed in a coronary vessel (such as a coronary sinus) of a patient is achieved by the steps of : identifying a coronary vessel for a procedure and placing a catheter (10) within the coronary vessel. The coronary vessel is occluded at a site proximal to a distal end (12) of the catheter. A contrast medium is injected into the coronary vessel through the catheter distal end for visualization of the procedure within the coronary vessel. Following the procedure, the contrast medium is removed through the catheter distal end and occlusion of the coronary vessel is discontinued.

In a method for substantially isolating -cardiac circulation from systemic circulation, flow between the coronary sinus (CS) and the right atrium is occluded using a venous collection device (300, 310, 320, 330, 340, 350) which may have a balloon (302, 342, 344, 352, 354) or a flange (326, 334) to achieve occlusion. The venous collection device has a collection lumen (308) and a support structure (304, 314, 324, 334) and is located in the coronary sinus. The support structure is used to maintain patency of the coronary sinus during collection of fluid through the collection lumen. An artificial flow path is provided between the collection lumen and the one or more coronary arteries, thus isolating the cardiac circulation. According to the method, cardiac pumping for systemic circulation can be maintained during isolation of the cardiac circulation. This allows drugs to be administered to the heart without being degraded by passing through the liver.
A method for treating an occlusion in a coronary artery of a patient includes percutaneously advancing an occlusion treatment tool (such as an angioplasty balloon or stent delivery device) through the vasculature of the patient and into a coronary artery to a site of the occlusion. Following the treatment of the occlusion, a therapeutic agent is admitted into the first coronary artery. The therapeutic agent is selected to treat microvasculature obstructions at a target cardiac tissue site distal to the site of the occlusion.
