Cutting electrosurgical unit Cresta B

coagulationbipolar cuttingmonopolar cutting

Overview
Cresta B is a compact electrosurgical generator on the Cresta Digital keypad‑LED platform, providing one monopolar and one bipolar output with SafeTis tissue impedance feedback and ContactIQ return‑electrode monitoring. It operates at 450 kHz and includes a Program Manager for up to 100 profiles. Intended for cardiac, neuro and general procedures that do not require integrated vessel sealing or saline bipolar on the same generator.

Key highlights

• 7‑segment LED interface for simple parameter readout
• SafeTis tissue impedance feedback for consistent effect
• ContactIQ return‑electrode monitoring
• 450 kHz operating frequency for stable tissue response
• Program Manager with up to 100 configurable profiles
• Pure Cut: 300 W @ 500 Ω (maximum)
