Intended Use

Integra SL is intended to fragment urinary stones in the kidney (renal pelvis and renal calyces) and upper ureter.

Device Description

Integra SL is a transportable Electromagnetic (EM) Extracorporeal Shock Wave Lithotripter (ESWL) used for urinary stones treatment. The device consists of a Shock Wave Generator (SWAG), a Urological Table (UT) and the remote controls. Integra SL also contains the necessary interfaces for fluoroscopic and (or) ultrasonic imaging devices. The device has no Software control.

Integra SL includes the following features:

  • EM Shockwave generator with parabolic reflector for focusing mechanism
  • Swinging reflector (i.e. shockwaves are produced by angularly moving the shockwave while keeping the Therapeutic focus (F2) at the stone such that the shockwaves converge on the stone from multiple orientations).
  • A stand alone UT unit
  • Modular construction

7. Type of Ground Truth Used

  • Not applicable. No clinical tests were performed. The "ground truth" for this submission refers to compliance with safety and performance standards for a physical device.

8. Sample Size for the Training Set

  • Not applicable. This is not an AI/ML device requiring a training set.

9. How the Ground Truth for the Training Set Was Established

  • Not applicable. This is not an AI/ML device requiring a training set.

Summary of the Study that Proves the Device Meets Acceptance Criteria:

The Direx Systems Corporation Integra SL device's acceptance criteria are primarily based on its compliance with a series of recognized international and national standards for medical devices, specifically those pertaining to Extracorporeal Shock Wave Lithotripters (ESWLs). The document lists several IEC, ANSI/AAMI/ISO standards, and FDA guidance documents.

The study proving the device meets these criteria is described as "Performance Testing" within the 510(k) submission. This does not involve clinical trials or studies with human subjects. Instead, it refers to in-house engineering and laboratory testing to ensure the device's design and functionality align with the safety, electrical, mechanical, and performance specifications outlined in the referenced standards. The submission asserts that the Integra SL "was tested according to the following standards:" and implicitly states that by meeting these standards, it fulfills the performance requirements.

The submission also leverages a "special 510(k)" pathway, stating that the Integra SL "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, Integra." This implies that the safety and effectiveness are largely established through the predicate device's prior clearance and the current device's adherence to the same core technology and performance standards, without new clinical data being necessary for this specific modification.

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 (Premarket Approval), 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.

§ 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.”)
