Abstract: An ICE imaging system is disclosed, which comprises an Intracardiac echocardiography (ICE) catheter having a longitudinal axis, a proximal end, and a distal end. The ICE catheter corresponds to a micro-electromechanical (MEMS) or other transducer based phased array ultrasound catheter with an out diameter of 6 French or smaller for delivery through an internal jugular, subclavian, axillary, innominate venous system into heart chambers for the purpose of lead placement for a pacemaker or other implantable cardioverter defibrillator (ICD) device. Further, a catheter shaft houses an electronic flex cable which is in communication with at least one signal trace, and is configured to direct a plurality of transducer array elements to transmit and receive ultrasound beams, receive at least one signal from the plurality of transducer array elements, and construct at least one image of at least a portion of the heart based on the at least one signal.
