Abstract
A blood flow pathway is formed between a left atrium and a coronary sinus for relieving elevated left atrial pressure. The treatment method includes providing first and second delivery catheters, wherein a medical device is carried by the second delivery catheter. A side outlet opening of the first delivery catheter is positioned within the coronary sinus and oriented toward a left atrium. An anchor on the first delivery catheter contacts an inner surface of the coronary sinus for stabilization. A distal portion of the second delivery catheter is advanced through the side outlet opening. A puncture component is then passed through a target wall portion for creating the blood flow pathway. The medical device is positioned in the opening.
