The description focuses on the physical mechanism of ultrasonic ablation and does not mention any AI/ML components or functions.
Yes
The device is described as an "Ultrasonic Lesion Generating System" intended for "ablation of soft tissue," which directly implies a therapeutic function by causing tissue necrosis for treatment purposes.
No
This device is described as an "Ultrasonic Lesion Generating System" used for the "ablation of soft tissue." Its function is to create lesions (necrosis) in tissue through concentrated energy, which is a therapeutic intervention, not a diagnostic one.
No
The device description clearly outlines hardware components including a generator, hand-held handpiece with piezoelectric crystals, and a Coupling Fluid Recirculation System. It is a physical device that uses ultrasound energy for tissue ablation.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for the "laparoscopic or intraoperative ablation of soft tissue." This describes a surgical procedure performed directly on a patient's body.
- Device Description: The device description details a system that uses ultrasound energy to heat and destroy tissue within the body. This is a therapeutic intervention, not a diagnostic test performed on samples outside the body.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue samples, etc.) or providing diagnostic information about a patient's health status based on such analysis.
IVD devices are designed to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. The Sonatherm system performs a therapeutic action (tissue ablation) directly on the patient.
N/A
Intended Use / Indications for Use
The Sonatherm is indicated for the laparoscopic or intraoperative ablation of soft tissue from the ultrasound focal zone back to the surface of the targeted treatment area in General Surgery.

Device Description
Sonatherm 600 Ultrasonic Lesion Generating System is comprised of a generator, which feeds a 3 to 5 MHz electrical signal to one or more piezoelectric crystals mounted in a hand-held handpiece; the crystals then vibrate at the same frequency. A Coupling Fluid Recirculation System is provided to provide a temperature stabilized coupling/coolant fluid surrounding the Transducer crystal(s). The tluid is contained by a Hexible membrane surrounding the transducer head. A user interface provides Input Controls and Output Readouts for Operator. In operation, the Transducer Membrane is placed against the organ to be treated. When the unit is engaged, the transducer will vibrate, create acoustic waves in the coupling fluid that then couples to the organ tissue and propagates into it. The waves converge to a focal point that concentrates the energy within a finite tissue volume. As the temperature of the tissue rises above the ablation point, the tissue necroses. The treatment head is moved under Operator control to treat a preselected volume of tissue from the focal point back to the surface of the organ.

6. Comparison to Predicate Device
Sonatherm 600 Ultrasonic Lesion Generating System is similar in clinical use, safety and outcome to the Rita Medical Systems Model 500 (K983214) and 1500 RF (K993944) Generator Systems and Accessories, the AFx Inc. Microwave Surgical System and Accessories (K003978), the Endocare Cryocare Surgical System (K011074) and the Radionics RFG-3C RF Lesion Generator and accessories (K901540B). Although housed differently, all of the aforementioned devices allow the surgeon to target selected tissue for ablation in either laparoscopic or intraoperative modes and provide controlled energy input to the organ to facilitate said ablation. In the case of the Sonatherm 600, this volume is located from the focal point back to the surface of the organ. Ablated tissue may then be removed surgically or left intact for absorption and removal by the bodies normal cleansing mechanisms. Such treatment has been shown to be safe and efficacious over many decades of clinical use.
7 Safety and Performance Data
The Sonatherm 600 Ultrasonic Lesion Generating System has been designed to and will be tested to pass the following Voluntary Standards:
UL 2601-1 Medical Electrical Equipment, Part 1: General Requirements for Safety F.N 60601-1 Medical Electrical Equipment, Part 1 : General Requirements for Safety EN 60601-1-2:2001 Electromagnetic Compatibility FCC Part 18 EMC Requirements

Dear Mr. Manna:
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 (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. 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.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies.
