The Aqua Medical RF Vapor System is indicated for use in the coagulation and ablation of bleeding and non-bleeding sites in the gastrointestinal tract including but not limited to the esophagus. Indications include Esophageal Ulcers, Mallory-Weiss tears, Arteriovenous Malformations, Angiomata, Barrett's Esophagus, Dieulafoy Lesions, Angiodysplasia, Gastric Antral Vascular Ectasia (GAVE) and Radiation Proctitis (RP). The device is to be used in adults only.
Device Description
The Aqua RF Vapor Ablation System uses a catheter to deliver heated water vapor to the tissue surface undergoing treatment. The Aqua RF Vapor Ablation System is a catheter-based system for heating and coagulating tissue. The heat is delivered to the target tissue in the form of water vapor that is generated within the catheter tip using radiofrequency (RF) energy. Application of heat to the tissue results in coagulation and ablation of the tissues being treated. This technique avoids the need for direct RF energy application to heat the tissue. The Aqua Medical RF VaporAblation System consists of the following components: - Aqua RF Vapor Generator: A software-controlled RF generator is operated through a graphical user interface (GUI) and incorporates a syringe pump that delivers saline to the catheter. Delivery of bipolar RF energy to the catheter is controlled either by an accessory foot pedal or a button incorporated in the disposable catheter. - Aqua RF Vapor Catheters: disposable, sterile, single-use catheters with a diameter of 7F -(2.3 mm) with an outer catheter sheath that is 10.5F and a length between 145 cm and 210 cm. There are 3 types of RF Vapor catheters available. Catheters are designed to be used through an endoscope working channel diameter of 3.7mm. - Saline Delivery Tubing and Syringe: Tubing and syringe (60cc) provide a means of delivering saline to the catheter during treatment.
More Information

Not Found

No
The device description and performance studies focus on hardware, software control of RF energy and saline delivery, and the physical effects of vapor ablation. There is no mention of AI/ML algorithms for image analysis, treatment planning, or any other function.

Yes
The device is indicated for the coagulation and ablation of bleeding and non-bleeding sites in the gastrointestinal tract, addressing conditions such as ulcers, tears, and vascular malformations, which are therapeutic medical interventions.

No

The device is used for coagulation and ablation of tissue, which is a treatment, not a diagnostic, function.

No

The device description clearly outlines multiple hardware components including an RF generator, catheters, saline delivery tubing, and a syringe. While the generator is software-controlled, the device is not solely software.

Based on the provided information, the Aqua Medical RF Vapor System is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • IVD Definition: IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
  • Aqua Medical RF Vapor System Function: The description clearly states that this device is used for the "coagulation and ablation of bleeding and non-bleeding sites in the gastrointestinal tract". It directly treats tissue within the body using heat delivered via water vapor.
  • Lack of Specimen Analysis: There is no mention of the device analyzing any bodily fluids or tissues outside of the body. Its function is therapeutic, not diagnostic based on specimen analysis.

Therefore, the Aqua Medical RF Vapor System is a therapeutic device used for treating conditions within the gastrointestinal tract, not an IVD.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Hardware Verification Testing, Lean Beef Testing and Software Testing. The catheter joint forces and sliding forces passed the specification requirements for the testing. The fatigue cycle testing was completed to validate the physical integrity and durability of the subject device under simulated-use conditions including extreme tortuosity, mechanical cycling, high-vapor output and temperature exposure. The Lean Beef testing demonstrated equivalent results between the previous time-based treatment when compared to the modified energy level-based treatment. The test also demonstrated that the ablation depths for the modified Circumferential Delivery Catheters are substantially equivalent to those produced by the Predicate Circumferential Delivery Catheters through the dose ranges evaluated in the test. Equivalent ablation depths (penetration of heat) were produced by both systems supporting our substantial equivalency claim.

SUBSTANTIAL EQUIVALENCE 6.

The reason for this submission includes minor software and device modifications, addition of a new circumferential catheter size and to update the previously cleared indication to include the term "ablation". To support the requested modifications the company submitted supporting nonclinical data as well as justification for the addition of "ablation" to the indication. The proposed modifications do not introduce new safety and effectiveness concerns and support the company's substantial equivalency claim.

7. PERFORMANCE DATA

In order to support the proposed modifications, the company conducted Hardware Verification Testing, Lean Beef Testing and Software Testing. The proposed modifications did not require new or supplemental biocompatibility, sterilization, packaging or shelf-life testing. Hardware Verification testing included fatigue cycle testing, catheter joint forces and sliding forces. The catheter joint forces and sliding forces passed the specification requirements for the testing. The fatigue cycle testing was completed to validate the physical integrity and durability of the subject device under simulated-use conditions including extreme tortuosity, mechanical cycling, highvapor output and temperature exposure. The Lean Beef testing demonstrated equivalent results between the previous time-based treatment when compared to the modified energy level-based
