Remote catheter system with steerable catheter

A catheter procedure system comprising:

• a user interface for receiving at least a first user input and a second user input;
• a guide catheter having a guide catheter shaft with a proximal end and a distal end;
• a guide catheter actuating mechanism including a rotation actuator coupled to the proximal end of the guide catheter, and an advance/retract actuator, the advance/retract actuator of the guide catheter actuating mechanism configured to advance and retract the guide catheter in response to the first user input and to rotate the proximal end of the guide catheter in response to the second user input;
• a Y-connector including a first leg, a second leg, and a third leg, each of the first leg, second leg and third leg having an internal lumen, each lumen being in communication with each other, the first leg being co-axial with the third leg and the second leg extending at an angle from the first leg, the internal lumen of the first leg being in communication with an internal lumen o the guide catheter;
• and
• a first connector coupling the Y-connector to the guide catheter actuating mechanism, wherein the first connector is configured to allow the Y-connector to advance and retract with the guide catheter and to allow the proximal end of the guide catheter to rotate without also causing the Y-connector to rotate, wherein at least a portion of the rotation actuator is between a portion of the first leg and a portion of the guide catheter.
