The CARTOSOUND Module with SOUNDSTAR Catheter utilizes 3D ultrasound technology for enhanced performance when carrying out complex procedures, such as ventricular tachycardia and atrial fibrillation. The intracardiac echo produced offers a variety of benefits while increasing safety and certainty. The complete cardiac anatomy can be visualized and mapped. The CARTO System environment enables viewing of the ultrasound image and pinpointing the accurate location. It contains an ultrasound transducer comprised of a 64 crystal element phased-array. The tip-to-tissue can be monitored and a map can be drawn of the esophagus. The transseptal puncture can be tagged. The catheter has an ergonomically designed 4-way steering handle.
