No
The summary describes a traditional medical device for lithotripsy with standard components and testing focused on safety and performance, with no mention of AI or ML.
Yes
Explanation: The device is indicated for the fragmentation of urinary tract stones, which is a therapeutic intervention.
Yes
The device description explicitly states that the Gemini is designed for "diagnostic and therapeutic procedures usual in Urology," and it includes an "ultrasound unit" as a component, which is commonly used for diagnostic purposes.
No
The device description explicitly lists multiple hardware components including a basic unit with integrated X-ray C-arm and therapy arm, a patient table, a control desk, and an ultrasound unit. This indicates it is a hardware-based medical device with integrated software, not a software-only device.
Based on the provided information, the Gemini 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 a urological workstation for extracorporeal shock wave lithotripsy (ESWL) and other urological procedures. It involves physical interaction with the patient (shock waves) and imaging modalities (X-ray, Ultrasound) to guide the treatment.
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health. The Gemini does not perform such tests.
The Gemini is a medical device used for a therapeutic procedure, not for diagnosing conditions by analyzing samples outside the body.
N/A
Intended Use / Indications for Use
The Gemini is indicated for the fragmentation of urinary tract stones, i.e., renal calyceal stones, renal pelvic stones, and upper ureteral stones.

Device Description
The Gemini is a modular urological work station designed for extracorporeal shock wave lithotripsy ("ESWL") and for diagnostic and therapeutic procedures usual in Urology. The Gemini is composed of the following modules: (1) basic unit with integrated X-ray C-arm and therapy arm for shockwave treatment; (2) patient table; (3) control desk – user interface; and (4) ultrasound unit.
As indicate above, the Gemini is an extracorporeal shock wave lithotripter used for fragmentation of urinary tract stones, i.e., renal calyceal stones, renal pelvic stones, and upper ureteral stones. The technology to perform this function involves use of an electromagnetic shock wave emitter ("EMSE"). In the case of the subject device and the predicate devices, the identical shock wave source is used. This source, the 140f EMSE, has a well-established record of performance and also is utilized in other Lithotripers that have been cleared by FDA (e.g., Dornier Compact Alpha (K002929) and Dornier Compact Delta (P840008, S066)).
The other elements of the Gemini, i.e., the patient table and the X-ray unit, are also are similar to that of other cleared stationary Lithotripters, the Doli 140 (K011773) and the Dornier Lithotriper (P840008, S062). They perform the same function and operate in the same manner during the procedures involved in the fragmenting of urological stones.

In all instances, the Gemini Lithotripter functioned as intended and results observed were as expected.
In addition, the system and its software was tested and validated during the company's design control process and the system met all acceptance criteria. The anti-collision system of the subject device was verified to perform as designed to mitigate the risk of injury. The methodology for accurately locating the stone was tested during the design verification testing and the assessment demonstrated that the system is capable of locating the shock wave focus area with sufficient accuracy. Lastly, the device manual was reviewed and approved as part of the design control process. It contains all necessary warnings, cautions and instructions to mitigate potential injuries.

§ 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)
