Abstract
A method is provided for increasing blood flow in or about a cardiac structure to prevent thrombosis. One step of the method includes providing an implantable sprayer having an elongated tubular body with proximal and distal end portions. The distal end portion includes at least one opening and an anchoring mechanism. The distal end portion of the implantable sprayer is inserted into a cardiac chamber that includes the cardiac structure. The anchoring mechanism is then deployed so that the distal end portion of the implantable sprayer is secured in or about the cardiac structure. Next, the proximal end portion is anastomosed with an artery so that blood flows through the elongated tubular body of the implantable sprayer and is sprayed out of the at least one opening to continuously circulate blood in or about the cardiac structure.
