Monopolar cutting electrosurgical unit Cresta Is

bipolar cuttingcoagulationmonopolar coagulation

Overview
The Cresta Is is an electrosurgical generator featuring split‑port wiring to provide dedicated monopolar, bipolar and SureBind vessel sealing functions. It supports reproducible vessel seals up to 7 mm and delivers standard cut and coagulation modalities via a clear 7‑segment LED interface. SafeTis impedance feedback helps control tissue response for both laparoscopic and open procedures.

Key highlights

• Split port (dedicated bipolar and vessel sealer connectors)
• 7‑segment LED interface
• SafeTis tissue impedance feedback
• Vessel Sealer (High) up to 150 W
• Ordering code LF90122

Notes
The values above are maximum ratings. Output power values may vary by ±20%; peak voltage and crest factors change accordingly. Power can be reduced during procedures by selecting lower settings. Always use the lowest power that achieves the required surgical effect. Vessel Sealer power is modulated.
