A stabilized coronary sinus catheter system having a proximal section and a distal section with a memory shape portion, and a tip, distal of the memory shape portion. A handle having a body, a tip deflection actuator, a memory shape portion deployment actuator, and an axis. The tip is in line with the axis and the tip deflection actuator is at a first position. The tip is deflected out of alignment with the axis when the tip deflection actuator is at a second position. A third position is a delivery configuration where the memory shape portion and the tip are in line with the axis. The memory shape portion deployment actuator is at a first location. A deployed configuration allows the memory shape portion to form a predetermined shape conforming to the shape of the coronary sinus when the memory shape portion deployment actuator is at a second location.
