Delivery system for a heart valve support device

A method for positioning a device for assisting with functioning of a valve of a heart comprising:

• advancing a flexible member through a delivery shaft until it butts up against a shaft of the device;
• axially translating the flexible member, to adjust a height of a flow optimizer fixed to the shaft relative to an anchoring assembly of the device;
• and
• fixing the shaft to the anchoring assembly, thereby fixing the position of the flow optimizer relative to the shaft, further comprising navigating a steerable catheter through the catheter, the steerable catheter having a distal section comprising a distal portion, a midportion, and a proximal portion, further comprising deflecting the distal portion in a first direction and amount, the midportion in a second direction and amount, and the proximal portion in a third direction and amount, wherein the first, second, and third directions and amounts are different from one another.
