Tissue feedback defines energy delivery instead of a static wattage chase
tissue sensing technology
SafeZ™
Adaptive energy delivery with real-time tissue monitoring.
Real-time
Tissue impedance monitoring
Why stakeholders care
Supports consistent cut and coagulation as impedance changes mid-activation
Backbone for Cresta features such as ContactIQ, SureBind, TURiCUT, and ReSaliX
Clinical context
Clinical problem
Fixed-output electrosurgery can overshoot when tissue impedance shifts mid-activation. Near vessels, nerves, and thin walls that means excess thermal spread, char, and unpredictable cut quality that forces surgeons to chase power settings case by case.
Mechanism
SafeZ continuously monitors tissue impedance in real time and dynamically adjusts Cresta output within microseconds, maintaining consistent tissue effects as conditions change.
How it works
Step 01
Sense tissue impedance continuously during energy delivery
Step 02
Adjust generator output within microseconds as impedance shifts
Step 03
Hold a more consistent tissue effect across open, laparoscopic, and sealing work
