The summary describes a standard electrohydraulic lithotripter with different operating modes. There is no mention of AI, ML, image processing, or any data-driven decision-making components. The performance studies focus on electrical and safety standards, not algorithmic performance.
Yes.
The device is used for the "Fragmentation of urinary tract stones," which is a medical treatment.
No
The device description indicates it is an Electrohydraulic Extracorporeal Shock Wave Lithotripter used for fragmenting urinary tract stones, which is a therapeutic function, not diagnostic.
No
The device description explicitly details hardware components like a Shock Wave Generator and a Motorized Floating Treatment Table, and the performance studies reference standards for electrical and medical equipment, indicating a physical device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is the "Fragmentation of urinary tract stones". This is a therapeutic procedure performed directly on the patient's body.
- Device Description: The device is an "Electrohydraulic Extracorporeal Shock Wave Lithotripter". This is a physical device used to generate shock waves to break up stones within the body.
- Lack of IVD Characteristics: IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening. This device does not perform any such examination of specimens.
Therefore, the Duet Lithotripter is a therapeutic medical device, not an in vitro diagnostic device.

§ 876.5990 Extracorporeal shock wave lithotripter.
(a)
Identification. An extracorporeal shock wave lithotripter is a device that focuses ultrasonic shock waves into the body to noninvasively fragment urinary calculi within the kidney or ureter. The primary components of the device are a shock wave generator, high voltage generator, control console, imaging/localization system, and patient table. Prior to treatment, the urinary stone is targeted using either an integral or stand-alone localization/imaging system. Shock waves are typically generated using electrostatic spark discharge (spark gap), electromagnetically repelled membranes, or piezoelectric crystal arrays, and focused onto the stone with either a specially designed reflector, dish, or acoustic lens. The shock waves are created under water within the shock wave generator, and are transferred to the patient's body using an appropriate acoustic interface. After the stone has been fragmented by the focused shock waves, the fragments pass out of the body with the patient's urine.(b)
Classification. Class II (special controls) (FDA guidance document: “Guidance for the Content of Premarket Notifications (510(k)'s) for Extracorporeal Shock Wave Lithotripters Indicated for the Fragmentation of Kidney and Ureteral Calculi.”)

4. Intended Use:
Fragmentation of urinary tract stones (i.e. renal calyceal, renal pelvic, and upper ureteral stones).
5. Technological Characteristics:
The Duet is a modification of an existing device that enables the use of 2 reflectors instead of one. The modified device has the same fundamental scientific technology and intended use as predicate devices.
6. Description
The Duet is a transportable Electrohydraulic Extracorporeal Shock Wave Lithotripter, which consists of a Shock Wave Generator (SWAG), a Motorized Floating Treatment Table (MFT), and control means. The Shock Wave Generator can be operated in 4 modes:
- a) Bottom Reflector only.
- b) Top reflector only.
- c) Alternate mode (asynchronous).
- d) Simultaneous mode (synchronous).
7. Performance Testing
The Duet Lithotripter was tested according to the following standards:
-
IEC 60601-1(1988) +A1 (1991) +A2 (1995)
-
IEC 60601-1-1 (2000)
-

-
IEC 60601-2-38 (1996) +A1 (1999)
-
UL 2601-1-1997, CSA-C22.2 No. 601.1
-

8. Clinical Tests
No clinical tests were performed.
9. Conclusion
The Duet meets the requirements for a special 510(k) by the virtue of being a minor modification, which does not change the fundamental technology or reduce safety and effectiveness, of the Company's predicate device, the Tripter X-1 Compact.

Dear Ms. Gershtein:
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 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.
