Intended Use
The Sonata® Transcervical Fibroid Ablation System 2.2 is intended for diagnostic intrauterine imaging and transcervical treatment of symptomatic uterine fibroids, including those associated with heavy menstrual bleeding.
Device Description
The Sonata System 2.2 provides radiofrequency (RF) ablation of uterine fibroids using a transcervical approach that is uterine sparing without incisions or material uterine distension. The system enables a clinician to deliver radiofrequency energy to fibroid tissue resulting in thermal fixation and coagulative necrosis of the tissue. The system combines two technologies - ultrasound for visualization, and radiofrequency energy for ablative therapy - in a single integrated handpiece. The Sonata System is comprised of medical equipment, software, and various single-use and reusable instruments. A single-use Radiofrequency Ablation (RFA) Handpiece attaches to a reusable Intrauterine Ultrasound (IUUS) Probe to provide sonography-guided RF ablation. Once connected, the combination is referred to as the "Treatment Device". The RFA Handpiece connects to the Sonata RF Generator and contains the Needle Electrodes that deliver radiofrequency energy to the target tissue. The IUUS Probe connects to the SMART Tablet and provides diagnostic ultrasound imaging and guidance. Ultrasound guidance is used to localize the fibroids from within the uterine cavity, guide placement of the RFA Handpiece Needle Electrodes into a target fibroid and ensure safety with respect to the serosa. The Sonata System allows for treatment planning through the use of a graphical interface and automated control of RF energy delivery. Sonata Graphical Guidance Software (GGS) includes the SMART Guide and integrates treatment planning, targeting, and ablation of fibroids. The SMART Guide displays a real-time graphic overlay on the live ultrasound image for targeting and deployment of radiofrequency ablation.
More Information

No
The description focuses on standard medical device technologies (ultrasound, RF ablation, software for guidance and control) and does not mention any AI or ML components. The "SMART Guide" appears to be a graphical overlay, not an AI-driven feature.

Yes
The device is intended for the transcervical treatment of symptomatic uterine fibroids, including those associated with heavy menstrual bleeding, and it uses radiofrequency ablation to deliver therapy.

Yes

Explanation: The "Intended Use / Indications for Use" section explicitly states that the device is "intended for diagnostic intrauterine imaging". The "Device Description" also mentions that the IUUS Probe "provides diagnostic ultrasound imaging and guidance".

No

The device description explicitly states that the Sonata System is comprised of medical equipment, software, and various single-use and reusable instruments, including a handpiece, probe, and RF generator. This indicates it is a system with significant hardware components, not a software-only device.

Based on the provided information, the Sonata® Transcervical Fibroid Ablation System 2.2 is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • Intended Use: The intended use clearly states "diagnostic intrauterine imaging and transcervical treatment of symptomatic uterine fibroids". While it includes a diagnostic component (imaging), the primary purpose is treatment (ablation). IVD devices are primarily used for diagnosis or disease monitoring outside of the body, using samples like blood, urine, or tissue.
  • Device Description: The description details a system that uses ultrasound for visualization within the body and radiofrequency energy for ablation within the body. This is a therapeutic device with integrated imaging for guidance.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples, reagents, or performing tests on specimens outside of the patient's body, which are hallmarks of IVD devices.

Therefore, the Sonata System 2.2 is a therapeutic device with integrated imaging capabilities.

Device Description

The Sonata System 2.2 provides radiofrequency (RF) ablation of uterine fibroids using a transcervical approach that is uterine sparing without incisions or material uterine distension. The system enables a clinician to deliver radiofrequency energy to fibroid tissue resulting in thermal fixation and coagulative necrosis of the tissue. The system combines two technologies - ultrasound for visualization, and radiofrequency energy for ablative therapy - in a single integrated handpiece.

The Sonata System is comprised of medical equipment (Figure 1), software, and various single-use and reusable instruments. A single-use Radiofrequency Ablation (RFA) Handpiece attaches to a reusable Intrauterine Ultrasound (IUUS) Probe as shown in Figure 2 to provide sonography-guided RF ablation. Once connected, the combination is referred to as the "Treatment Device". The RFA Handpiece connects to the Sonata RF Generator and contains the Needle Electrodes that deliver radiofrequency energy to the target tissue. The IUUS Probe connects to the SMART Tablet and provides diagnostic ultrasound imaging and guidance. Ultrasound guidance is used to localize the fibroids from within the uterine cavity, guide placement of the RFA Handpiece Needle Electrodes into a target fibroid and ensure safety with respect to the serosa. When the Needle Electrodes are anchored within tissue, the physician is able to pivot the IUUS Probe transducer around the Needle Electrodes in order to confirm safety of the uterine serosa through multiple ultrasound planes. The Sonata System allows for treatment planning through the use of a graphical interface and automated control of RF energy delivery. Sonata Graphical Guidance Software (GGS) includes the SMART Guide (Figure 3) and integrates treatment planning, targeting, and ablation of fibroids. The SMART Guide displays a real-time graphic overlay on the live ultrasound image for targeting and deployment of radiofrequency ablation.

A single-use Radiofrequency Ablation (RFA) Handpiece attaches to a reusable Intrauterine Ultrasound (IUUS) Probe as shown in Figure 2 to provide sonography-guided RF ablation. Once connected, the combination is referred to as the "Treatment Device". The RFA Handpiece connects to the Sonata RF Generator and contains the Needle Electrodes that deliver radiofrequency energy to the target tissue. The IUUS Probe connects to the SMART Tablet and provides diagnostic ultrasound imaging and guidance. Ultrasound guidance is used to localize the fibroids from within the uterine cavity, guide placement of the RFA Handpiece Needle Electrodes into a target fibroid and ensure safety with respect to the serosa. When the Needle Electrodes are anchored within tissue, the physician is able to pivot the IUUS Probe transducer around the Needle Electrodes in order to confirm safety of the uterine serosa through multiple ultrasound planes.

The Sonata System allows for treatment planning through the use of a graphical interface and automated control of RF energy delivery.

Sonata Graphical Guidance Software (GGS) includes the SMART Guide (Figure 3) and integrates treatment planning, targeting, and ablation of fibroids. The SMART Guide displays a real-time graphic overlay on the live ultrasound image for targeting and deployment of radiofrequency ablation.

Image /page/6/Figure/5 description: The image shows a diagram of the SMART Guide system. The diagram includes two images, one of an ultrasound and one of a fibroid. The ultrasound image shows the IUUS Probe Tip, Introducer Guide, Ablation Zone, and Thermal Safety Border. The fibroid image shows the Ablation Zone and Thermal Safety Border. The text in the image describes the SMART Guide system and how it is used to set margins of ablation in real time.

Figure 3 Sonata SMART Guide

Two main elements of the SMART Guide are the Ablation Zone and the Thermal Safety Border.

  • . Ablation Zone (red inner ellipse) – a two-dimensional representation of the outer boundary of the average region of tissue ablation for the selected ablation size
  • . Thermal Safety Border (green outer ellipse) - the distance at which tissue outside of the Ablation Zone is safe from the potential of thermal damage.

Performance Testing

Gynesonics has applied their design control procedures including risk analysis to evaluate the modifications to the device which are the subject of this 510(k). For each change, verification and as required, validation was conducted on the modified device to demonstrate that the modified device meets the applicable design requirements. The test methods and acceptance criteria used established methods consisting of FDA recognized standards and/or the same methods and criteria as were used in the predicate device submission; thus, meeting the FDA's requirement for a Special 510(k). Table 5 summarizes the design control activities. In all cases, the verification and validation testing met the acceptance criteria.
