Arm Intervention/treatment
Experimental: Exablate Treated Arm
Treatment with Exablate Prostate 2100 Type-3 System
Device: Exablate Prostate Treatment
The Exablate system is a non-invasive thermal ablation device that is being used to ablate tissue. The system combines a focused ultrasound surgery (FUS) delivery system and MRI scanner.
Other Names:
  • Exablate Prostate
  • Exablate MRgFUS

Primary Outcome Measures :
  1. Incidence and severity of device/procedure-related complications following treatment [ Time Frame: 12 months ]
    Safety will be evaluated by incidence and severity of device/procedure-related complications following treatment. Adverse events will be recorded and categorized according to severity and relationship to the biopsy procedure, the Exablate procedure, or to the Exablate device. They will be classified based on body system, severity, and frequency.

  2. Proportions of treated subjects reporting negative Gleason 7 biopsy within the prostate biopsy treatment area. [ Time Frame: 6 months ]
    Effectiveness will be evaluated by targeted lesion control based on biopsy results. Proportions of treated subjects reporting negative Gleason 7 biopsy within the treatment area and/or MRI verification of index lesion(s) ablation. PSA results and validated subject-reported questionnaires will be summarized.
