Johnson & Johnson GEN11 Electrosurgical Unit (ESU)

The Ethicon GEN11 Generator is a next-generation energy platform engineered to power HARMONIC® ultrasonic and ENSEAL® advanced bipolar instruments for both open and laparoscopic surgery. With adaptive energy delivery, universal connector, and a user-friendly touchscreen, it optimizes tissue interaction while simplifying surgical workflows.

Overview

Designed for flexibility and future readiness, the GEN11 supports seamless transitions between ultrasonic and bipolar modes with automatic instrument recognition. Adaptive Tissue Technology continuously modulates energy delivery based on real-time feedback, providing consistent performance across varying tissue types with reduced thermal spread.
