No
The summary does not mention AI, ML, or related terms, and the device description focuses on hardware components and a standard imaging modality (ultrasound) for positioning.
Yes
The device is described as a "Shock Wave Lithotripter" intended for the "fragmentation of urinary tract stones," which is a treatment for a medical condition.
No
This device is an extracorporeal shock wave lithotripter intended for the fragmentation of urinary tract stones. While it uses sonographic localization for positioning, its primary function is therapeutic (fragmentation of stones), not diagnostic.
No
The device description explicitly states it consists of hardware components: a Shock Wave Generator, a Motorized Floating Treatment Table, and control means.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health. This testing is done outside the body (in vitro).
- Device Function: The Duet SP Extracorporeal Shock Wave Lithotripter is used to fragment stones within the urinary tract inside the patient's body. It uses shock waves applied externally.
- Lack of Specimen Analysis: The device does not analyze any biological specimens taken from the patient. Its function is a therapeutic intervention, not a diagnostic test performed on a sample.
Therefore, based on the provided information, the Duet SP Extracorporeal Shock Wave Lithotripter is a therapeutic device, not an IVD.

§ 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:
The intended use of the Duet SP Extracorporeal Shock Wave Lithotripter is the fragmentation of urinary tract stones (i.e. renal calyceal, renal pelvic, and upper ureteral stones).
5. Technological Characteristics:
This Duet includes a sonographic localization option that enables the use of ultrasound for positioning. The 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.
7. Clinical Tests
No clinical tests were performed.
8. Conclusion
The Duet with the Sonographic Localization Option 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 devices: Duet K023535 and Duet SLO K041582.
