Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. ≥50 years of age; with life expectancy of ≥10 years
  2. 20-80 cc prostate size determined by MRI Central Imaging
  3. ≤15 ng/ml PSA
  4. Cancer stage less than or equal to T2c
  5. Within 12 months prior to signing consent have had a multiparametric MRI. Within 6 months prior to signing consent, have undergone a multiparametric MRI software guided fusion biopsy of the prostate (transrectal or transperineal). This must include a standard sector biopsy obtaining a minimum of 10-16 cores.
  6. <15mm diameter of qualifying lesion as measure by greatest diameter
  7. Subject is willing and able to adhere to specific protocol visits and required testing throughout study
  8. Is geographically stable and near the site or able and willing to travel back to site for follow-up visits involving diagnostic tests or treatment
  9. Able and willing to provide written consent to participate in the study.

Exclusion Criteria:

  1. Patients with >GGG3 cores anywhere in the prostate
  2. MRI evidence of extracapsular extension of cancer (MRI read as "definite", "frank" or "gross" ECE)
  3. All PI-RADS 5 lesions
  4. All MRI Central Imaging confirmed by PI-RADS 4 lesions negative on biopsy
  5. Contraindications to MRI
  6. Subjects with an installed pacemaker or other potentially electrically conductive implants implanted within 200mm (8 inches) of the procedure area. Implants that are within 200mm (8 inches) and can be turned off for the duration of the study procedure are acceptable.
  7. Any prior surgery, intervention, or minimally invasive therapy, (MIST) for the prostate cancer or bladder neck.
  8. Treated within the past 5 years for genital cancer
  9. Presence of any urethral or prostatic condition that precludes water vapor ablation per Instructions for Use
  10. Currently taking medications that have hormonal effects on the prostate or PSA, such as: 5 alpha reductase inhibitors (if on for <6 months), Androgen blockers, Luteinizing hormone-releasing hormone (LHRH) agonists or antagonists (12 month wash-out), or Testosterone supplementation
  11. Active urinary tract infection
  12. Active or clinically chronic prostatitis or granulomatous prostatitis
  13. Treated within the past 5 years for a lower and/or upper urinary tract malignancy (excluding prostate cancer meeting the inclusion criteria)
  14. Any rectal pathology, anomaly or previous treatment that could change properties of rectal wall or insertion and use of TRUS
  15. Unable to stop taking antiplatelet medications or other blood thinning agents
  16. Known allergy to nickel
  17. Allergic to medication required by the study such as MRI contrast or anesthesia
  18. Any significant medical history that would pose an unreasonable risk or make the subject unsuitable for the study
  19. Any cognitive or psychiatric condition that interferes with or precludes direct and accurate communication with the study Investigator regarding the study or affects the ability to complete the study quality of life questionnaires
  20. Subject currently participating in other premarket investigational studies unless approved by Sponsor in writing
  21. Subject is considered vulnerable such as incarcerated or cognitively impaired.
