Intended Use

The Vanquish Water Vapor Ablation System is indicated for the thermal ablation of targeted prostate tissue via a transurethral approach.

Device Story

Vanquish Water Vapor Ablation System provides focal thermal ablation of prostate tissue using water vapor energy. Procedure performed in outpatient setting under transrectal ultrasound (TRUS) guidance. System heats sterile water to generate vapor, delivered via transurethral needle with emitter holes into prostate tissue. Includes stabilization and needle guidance systems. Physician operates device to target tissue; thermal energy causes ablation. Output is ablated prostate tissue; clinical benefit is treatment of prostate cancer. Healthcare provider uses TRUS to visualize placement and monitor procedure. Clinical decision-making relies on real-time imaging and device performance to ensure targeted ablation.

Clinical Evidence

Prospective, single-arm pivotal study (VAPOR 2, NCT05683691) of 235 patients; interim analysis of 110 intermediate-risk prostate cancer patients. Primary endpoints: 74% negative biopsy rate at 6 months (95% CI: 64%-82%); 21% average prostate volume reduction at 6 months; 52% PSA reduction at 12 months. Safety: No UADEs or serious device-related AEs; 94% of AEs non-serious; 96% of device/procedure-related AEs mild to moderate (CTCAE 1 or 2).

Technological Characteristics

Transurethral ablation device using water vapor energy. Features include stabilization system and needle guidance system. Bench testing included functional performance, biocompatibility, software V&V, cybersecurity, sterilization validation, electrical safety, and EMC. Complies with ISO 14155:2020.

Indications for Use

Indicated for thermal ablation of targeted prostate tissue via transurethral approach in patients with intermediate-risk prostate cancer.

Dear Alexia Haralambous:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: The Center for Devices and Radiological Health (CDRH) does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, the Food and Drug Administration (FDA) may publish further announcements concerning your device in the Federal Register.

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device"

| The Vanquish Water Vapor Ablation System provides a method of focal thermal ablation that utilizes the high energy stored in water vapor to target prostate tissue. In a minimally invasive transurethral outpatient procedure performed under transrectal ultrasound (TRUS) guidance, sterile water is heated within the system and converted into vapor. This vapor is then delivered through small emitter holes at the distal end of a transurethral needle into the prostate tissue. | | |
| Intended Use/Indications for Use | | 21 CFR 807.92(a)(5) |

| Indications for Use Comparison | 21 CFR 807.92(a)(5) |
| --- | --- |
| Both the subject and predicate devices are intended for transurethral ablation of prostate tissue. Therefore, the devices have the same intended use. | |
| Technological Comparison | 21 CFR 807.92(a)(6) |
| Both the subject and primary predicate device are transurethral ablation devices for prostate tissue which use water vapor as the source of ablation energy. Both are intended for partial gland ablation using the same delivery mechanism. However, they slightly differ in ablation energy levels, and the subject Vanquish device includes a stabilization system and a needle guidance system which the predicate Rezūm device does not have. Overall, the principle of operation, mechanism of action, and conditions of use between the subject Vanquish and predicate Rezūm devices are identical. | |
| Non-Clinical and/or Clinical Tests Summary & Conclusions | 21 CFR 807.92(b) |
| Francis Medical conducted functional performance bench testing, biocompatibility testing, software verification & validation, cybersecurity testing, sterilization validation, electrical safety and electromagnetic compatibility testing on the Vanquish system and components and provided the results as part of this submission to support the proposed indications for use. The performance of the Vanquish System is supported by the manufacturer sponsored VAPOR 2 (NCT05683691) pivotal study, a prospective, single-arm clinical study of an intermediate risk prostate cancer patient population to evaluate the safety and effectiveness of the Vanquish System to ablate targeted prostate tissue per the FDA Guidance Clinical Investigations for Prostate Tissue Ablation Devices. The VAPOR 2 study is being conducted in compliance with ISO 14155:2020 Clinical investigation of medical devices for human subjects – Good clinical practice. A total of 235 patients were treated with the Vanquish System at 26 sites in the United States from July 2023 to February 2025. An interim analysis of the first 110 patients treated with the Vanquish System followed to one year supports safety and effectiveness performance for this 510(k) submission. The VAPOR 2 study interim effectiveness endpoints per FDA Guidance are reported as follows using an intent-to-treat (ITT) approach in 110 focally treated subjects: • Biopsy Results: with worst case imputation, 74% of subjects (81/110) show negative biopsy at six months in targeted treatment field (two-sided exact 95% confidence interval: 64% to 82%). • Prostate Volume Reduction: average prostate volume reduction at 6-months for 110 subjects as measured by MRI is 21% (±13% standard deviation) • PSA Reduction for 108 subjects at 12-months is 52% (±28% standard deviation) The VAPOR 2 study interim safety endpoints per FDA Guidance are reported in the clinical study report attached to this submission. Safety and effectiveness data were collected at enrollment, Vanquish treatment, and follow-up visits at 7, 30, 90, 180, and 365 days. Subjects are being assessed for adverse events throughout the study. The VAPOR 2 study interim safety results are summarized as follows for 110 focally treated subjects: • No unanticipated adverse device effects (UADE) were reported, • No serious device-related adverse events were reported, • Nearly all (94%) reported adverse events were non-serious, and • Nearly all (96%) device and / or procedure-related adverse events were mild to moderate (CTCAE 1 or 2). The VAPOR 2 study confirms that the Vanquish System is safe and effective for the ablation of targeted prostate tissue. The use of the proposed device does not result in any new concerns about safety or effectiveness compared to the predicate device. Based on the intended use, technological characteristics, and the non-clinical and clinical evidence presented in this submission, the Vanquish System is substantially equivalent to the predicate device. | |
