Abstract:
A method of providing retrograde transvenous myocardial perfusion, the comprising:providing a device comprising a tubular member having a distal portion adapted to be disposed in a patient's venous system, a proximal end having means for sealing the proximal end, a first valve which opens when pressure distal to the first valve exceeds a predetermined maximum pressure and an occlusion element located on said distal portion; delivering the device into a portion of a patient's venous vasculature; using the occlusion element to substantially block blood flow at a selected location within the patient's venous vasculature; and opening the first valve when the venous blood pressure distal to the valve exceeds the predetermined maximum pressure, thereby allowing blood to flow through the first valve in the direction of normal venous blood flow so long as the pressure distal to the first valve is in excess of the predetermined maximum pressure.
