The Exablate Prostate System is indicated for endorectal MR-Guided Focused Ultrasound (MRgFUS) ablation of Prostatic Tissue.

The Exablate 2100 / 2100V1 Type 3.0 Prostate System (Trademark Name: Exablate Prostate System) is a high intensity Magnetic Resonance ("MR") image- guided focused ultrasound (MRgFUS) system intended for endorectal use that delivers focused ultrasound energy into the prostate in a minimally invasive manner by utilizing an endorectal probe transducer. The Exablate Prostate System combines a multiple-channel phased-array Focused Ultrasound (FUS) transducer probe and magnetic resonance imaging ("MRI") in a closed- loop treatment for the thermal procedure of Prostatic Tissue while monitoring the procedure in real time. The Exablate Prostate System is designed to work in conjunction with FDA cleared 1.5T and 3.0T MRI scanners with phased array torso cardiac coils that is used for guidance and procedure monitoring and control feedback. The Exablate Prostate System is fully integrated with the MRI scanner used to provide MR images of the patient's anatomy and prepare an appropriate procedure plan. Measured tissue temperature changes provide feedback on the procedure dose in the targeted area and its surroundings, allowing real- time monitoring to achieve safe and effective outcomes. The intended users for the Exablate Prostate System are trained and certified physicians and/or technicians (clinicians) who are seeking to offer patients an incisionless, focal, and MR guided and controlled prostate tissue ablation and have successfully completed the Insightec Exablate training to operate the device. The Exablate Prostate System platform is intended to ablate prostatic tissue with focused ultrasound and operates in conjunction with FDA cleared compatible MRI scanners for the purposes of real time procedure planning, MR based guidance of the focused ultrasound energy to the target region, MR thermal imaging and ablation monitoring. The procedure effect of the Exablate Prostate System is achieved by accurately guiding the focus of the ultrasound energy to the target region. The energy is then repeatedly transmitted to the target until the desired outcome is achieved. The targeted area is defined based on MR images taken during the procedure, while patient is in procedure position. The procedure is constantly monitored in a real-time closed-loop MR thermal feedback. Once the targeting is complete, the outcome is confirmed with adequate post-procedure MR imaging sequences.
