The instrument, AcuNav™ Catheter has a Doppler modes and a high resolution 2 D grey scale which helps the physician to have a better understanding of the structural orientation during visualizing cardiac chamber borders and transseptal puncture to assist avoid the improper punctures and confirmed tissue contact. Various clinical complications can also be effectively avoided with the help of the Catheter. Various complications are namely thrombus formation, pericardial effusion and wrong positioning of the device.The anatomic and physiologic detail can be easy visualized precisely and at the real time. Insight into the potential hazards and proximal anatomy can be improved with enhanced confidence and making diagnosis and therapy certain. The blood flow and velocity imaging by Doppler and myocardial wall motion is made possible. For precise positioning and the new views of the heart four way steering to 160° is available. The modular system setup and operation are open to the future EP Lab integration.
