Predictability drives confidence
Reproducible durable lesion formation4 supports the efficiency you need.
Width
Transcend limitations in challenging anatomies** with precise depth and width achieved with PFA controlled lesion stacking2
Depth
Achieve fast, transmural lesions, in a single application with reliable depth > 5 mm2
Applications in porcine ventricular tissue; confirmed via TTC stain (n=6 animals)
Achieve reproducible outcomes with consistent lesion quality that redefines safety

Seamless EnSiteTM X EP System integration with PFA Index (PI) - informed workflow. PI uses real-time tissue response to provide actionable insights on the progression of lesion formation7 and is designed to enable workflow consistency, the PI metric can be used as an additional tool for indication of lesion progression during PF energy delivery.
Predictive accuracy7
89%
For clinically relevant lesions
≥5 mm
Depth and width consistently produced when PI ≥ 51*
*Positive predictive value of 80% in healthy porcine ventricular tissue
Built to switch
Break free from one-size-fits-all solutions to tailored energy delivery that adapts to every patient, every procedure, every anatomy2,5
Feel the freedom of choosing the right energy for the right tissue with the ability to seamlessly switch between PF and RF1,4,10,11
