Claim 0:
1. A stabilized coronary sinus catheter system comprising:
a coronary sinus catheter comprising:
a proximal section comprising a proximal stiffness;
a medial section, distal of the proximal section and comprising a medial stiffness; and
a distal section comprising:
a memory shape portion;
a distal tip, distal of the memory shape portion; and
a flexibility greater than the proximal stiffness, the medial stiffness, and a stiffness of the memory shape portion;

a handle, disposed proximal of the proximal section comprising:
a body defining a center axis;
a distal tip deflection actuator configured to be in one of a first, second, or third position along the center axis so that:
(a) in the first position of the actuator, the distal tip is approximately in line with the center axis;
(b) in the second position of the actuator for deflection of the distal tip, the distal tip is out of alignment with the center axis; and
(c) in the third position of the actuator for delivery, the memory shape portion and the distal tip being approximately in line with the center axis; and

a memory shape portion deployment actuator configured to be in one of a first and second locations with respect to the center axis so that the memory shape portion deployment actuator is in the first location during delivery or deflection of the tip and in the second location for deployment of the memory shape portion that forms a predetermined shape approximately conforming to the shape of a coronary sinus of a patient.
