Introduction This user guide supplement provides information on the P21x transducer, compatible with the Sonosite Edge II ultrasound system. The Sonosite Edge II ultrasound system is a general purpose ultrasound system. It is intended for use by qualified physicians and healthcare professionals for evaluation by ultrasound imaging or fluid flow analysis of the human body. FUJIFILM Sonosite is adding an existing transducer, the P21x, to the Sonosite Edge II ultrasound system in compliance with USFDA Guidance Marketing Clearance of Diagnostic Ultrasound Systems and Transducers issued June 27, 2019. The P21x transducer is already marketed for use on Sonosite M-Turbo ultrasound system. This supplement adds the transducer with limited exam types to the Sonosite Edge II ultrasound systems, which are cardiac, abdomen and lung. The clinical indication for the Sonosite Edge II does not change from previous clearance. In accordance with the Enforcement Policy for Imaging Systems Used During the Coronavirus Disease 2019 (COVID-19) Public Health Emergency, FUJIFILM Sonosite reminds users that imaging devices are not intended for the diagnosis of COVID-19. In vitro diagnostic testing is currently the only definitive method to diagnose COVID-19.

Safety WARNING

To avoid device damage or patient injury, do not use the P21x needle-guide bracket on patients with pacemakers or medical electronic implants. The needle-guide bracket for P21x contains a magnet that is used to ensure that the bracket is correctly oriented on the transducer. The magnetic field in direct proximity to the pacemaker or medical electronic implant may have an adverse effect.
