Intended Use
The Lite-Med LM-9200ELMA Lithotripter is indicated for fragmentation of kidney stones such as renal calyx stones and renal pelvic stones and for upper, middle, and lower ureteral stones.
Device Description
The Lite-Med LM-9200 ELMA is an Electromagnetic Extracorporeal Shock Wave Lithotripter that effectively treats urinary calculi. It is routinely used for the fragmentation of kidney and ureteral stones and offers a good combination of clinical performance, flexibility and affordability. The standard LM-9200 ELMA device consists of a Shockwave Generator, an operator interface/touch panel, and a water circulation subsystem. Shock waves are generated on the basis of a principle similar to that used in loudspeakers. An electrical impulse is sent through an inductance coil, generating a magnetic ficld which repulses a metallic membrane. The acoustic impulse created by this repulsion is focused by an acoustic lens to form a shock wave. A water circulation subsystem is used to provide transmission of shockwaves and cooling of the generator. For the ESWL operation to be fully functional, two or three optional subsystems are needed. The first is a special treatment table. The second and third are a C-arm X-ray fluoroscope and an ultrasound imaging unit. The treatment table is a motorized floating table which can be moved electrically in all three axes.
More Information

No
The device description and performance studies focus on the mechanical and physical aspects of shockwave lithotripsy and do not mention any AI/ML components or capabilities. The "Mentions AI, DNN, or ML" field is also explicitly marked as "Not Found".

Yes
The device is indicated for the fragmentation of kidney stones and ureteral stones, which are medical conditions, and thus it is used to treat or alleviate a disease or injury.

No

The device is a therapeutic device for fragmenting kidney and ureteral stones using extracorporeal shock wave lithotripsy (ESWL). While it may use imaging (X-ray and ultrasound) for guidance, its primary function is treatment, not diagnosis.

No

The device description explicitly details hardware components such as a Shockwave Generator, operator interface/touch panel, water circulation subsystem, treatment table, C-arm X-ray fluoroscope, and ultrasound imaging unit. This is a hardware-based medical device.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
  • Device Function: The Lite-Med LM-9200ELMA Lithotripter is a therapeutic device. It uses shock waves to physically break up kidney and ureteral stones within the patient's body. It does not analyze samples taken from the body.
  • Intended Use: The intended use is for the fragmentation of stones, which is a treatment, not a diagnostic process.
  • Device Description: The description details the mechanism of generating and focusing shock waves for therapeutic purposes.
  • Imaging Modality: While it uses imaging (X-ray and ultrasound) for guidance, these are used to locate the stones for treatment, not to analyze biological samples.

Therefore, based on the provided information, the Lite-Med LM-9200ELMA Lithotripter is a therapeutic device, not an In Vitro Diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

The clinical investigations are performed at 2 sites with 1 and 2 weeks follow-up to support this application. Totally 40 (30 male, and 10 female) patients with stones were treated. The stones sizes treated were between 5 mm and 18 mm. None of the patients received general anesthesia. The overall success rate of the investigations is measured as 85%.

The experiences of physicians have shown that patients treated by the LM-9200 ELMA are safe and having high evaluations for the device function. And the user's manual is adequate for the operation of LM-9200 ELMA. The incidence of device malfunction does not happen in these clinical investigations.

§ 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)
