About Intuitive’s Products:

The da Vinci(r) Surgical System consists of a surgeon’s viewing and control console having an integrated, high-performance InSite(r) 3-D, HD vision system, a patient-side cart consisting of three or four robotic arms that position and precisely maneuver endoscopic instruments and an endoscope, and a variety of articulating EndoWrist(r) Instruments. By integrating computer-enhanced technology with surgeons’ technical skills, Intuitive believes that its system enables surgeons to perform better surgery in a manner never before experienced. The da Vinci(r) Surgical System seamlessly and directly translates the surgeon’s natural hand, wrist and finger movements on instrument controls at the surgeon’s console outside the patient’s body into corresponding micro-movements of the instrument tips positioned inside the patient through small puncture incisions, or ports.

The Aesop(r) Endoscope Positioner is a voice-activated robotic arm that automates the critical task of endoscope positioning, providing the surgeon with direct control over a smooth, precise and stable view of the internal surgical field.

The Hermes(r) Control Center is a centralized system designed to voice control a series of networked “smart” medical devices.
