Biosense is a new technology for left ventricular endocardial mapping and catheter-based intramyocardial therapeutics. The system reconstructs electromechanical maps of the left ventricle without using x-ray fluoroscopy. The 3-dimensional electromechanical maps generated by the system are utilized to precisely identify viable target zones based on integration of endocardial electrical and mechanical signals for online diagnosis of myocardial viability in the catheterization laboratory. It may be used for guidance of radiofrequency ablation and may potentially be used to apply intramyocardial therapy by its integration with a laser fiber for transmyocardial laser revascularization procedures.
