Indications for Use
The Swiss LithoClast® Trilogy is indicated for fragmentation and removal of urinary tract calculi in the kidney, ureter, and bladder.
Device Story
The Swiss LithoClast Trilogy is an intracorporeal lithotripter used by urologists to fragment and remove urinary tract stones. The system comprises a console, a reusable PEEK handpiece, and various stainless steel probes compatible with endoscopes. It operates in three modes: pneumatic (ballistic) lithotripsy, ultrasound lithotripsy, or a combined mode. The console generates energy via an electromagnetic field for ballistic shocks and a 24 kHz transducer for ultrasound vibrations. A two-step foot pedal controls energy delivery and suction. Suction is managed via an integrated peristaltic pump or an external vacuum system connected to a pinch valve. Stone fragments are collected in an optional stone catcher. The device is used in clinical settings. This submission specifically validates the use of hydrogen peroxide (H2O2) sterilization for the reusable handpiece, ensuring the device remains sterile for repeated clinical use.
Clinical Evidence
No clinical data. Substantial equivalence is supported by bench testing, specifically sterilization validation performed in accordance with ISO 14937:2009 using the STERRAD 100NX sterilizer to confirm the efficacy of the H2O2 sterilization cycle.
Technological Characteristics
Console-based lithotripter with microprocessor control, touchscreen I/O, and LCD display. Handpiece housing is PEEK; probes are 316L stainless steel. Energy sources: electromagnetic field (ballistic) and 24 kHz ultrasonic transducer. Connectivity: RFID tag for probe identification. Sterilization: Pre-vacuum steam or H2O2 (STERRAD 100NX). Suction: Peristaltic pump or pinch valve. Power: 100-240 VAC.
Indications for Use
Indicated for fragmentation and removal of urinary tract calculi in the kidney, ureter, and bladder.
Regulatory Classification
Identification
An electrohydraulic lithotriptor is an AC-powered device used to fragment urinary bladder stones. It consists of a high voltage source connected by a cable to a bipolar electrode that is introduced into the urinary bladder through a cystoscope. The electrode is held against the stone in a water-filled bladder and repeated electrical discharges between the two poles of the electrode cause electrohydraulic shock waves which disintegrate the stone.
Special Controls
The special control for this device is FDA's “Guidance for the Content of Premarket Notifications for Intracorporeal Lithotripters.”

#### F. Summary Device Description:
The Swiss LithoClast® Trilogy has three possible modes of operation: 1) pneumatic lithotripsy alone; 2) ultrasound lithotripsy alone; and 3) and combined pneumatic and ultrasound lithotripsy.
The LithoClast Trilogy system consists of the console used to set the treatment parameters and generate the treatment energy, a reusable handpiece, and a variety of probe sizes to enable use of the system with a wide range of commercially available endoscopes. Delivery of energy is controlled using a twostep foot pedal.
Two models of the LithoClast Trilogy are available: one with a peristaltic pump and one with a pinch valve. Both versions can be used to suction stone fragments into the optional Stone Catcher. An external vacuum system is required to enable suction with the pinch valve model of the console.

#### G. Intended Use / Indication for Use:
The Swiss LithoClast® Trilogy is indicated for fragmentation and removal of urinary tract calculi in the kidney, ureter, and bladder.
#### Technical Comparison with Predicate Device H.
The Swiss LithoClast® Trilogy described in this 510(k) has the same indications for use and technological specifications as previously described in K173234 (see below). The purpose of this Special 510(k) is to add the option of hydrogen peroxide (H2O2) sterilization using the Standard Cycle of the STERRAD 100NX sterilizer to the instructions for reprocessing the reusable handpiece.

#### l. Basis for Substantial Equivalence
Substantial equivalence of the Trilogy handpiece when sterilized using H2O2 was demonstrated by validation in accordance with ISO 14937:2009 Sterilization of health care products. General requirements for characterization of a sterilizing agent and the development, validation and routine control of a sterilization process for medical devices. Sterilization validation was conducted using the STERRAD 100NX sterilizer on the Standard cycle and demonstrated the achievement of sterility assurance level (SAL) 10-6.
{6}------------------------------------------------
#### J. Conclusion
The information and testing presented in this 510(k) demonstrate that the Swiss Lithoclast® Trilogy reusable handpiece, when sterilized using the STERRAD 100NX H2O2 sterilizer, is substantially equivalent to the handpiece when sterilized using steam.
