Intended Use

ShockPulse-SE Lithotripsy System is intended to be used for the fragmentation of urinary tract calculi in the kidney, ureter and bladder.

Device Story

Electromechanical device for fragmentation and aspiration of urinary tract calculi. System comprises generator, probes, transducer, cleaning stylet, wrench, power cord, nosecone, and optional footswitch. Operates via ultrasonic technology: transducer converts electrical energy into ultrasonic frequency vibrations (19,500–21,500 Hz) transmitted through a probe to mechanically break stones. Used in clinical settings by physicians. Output is physical fragmentation of calculi; healthcare providers use this to clear urinary tract obstructions. Benefits include effective stone removal.

Clinical Evidence

Bench testing only. Performance metrics included electrical safety, EMC/EMI, biocompatibility, bioburden, EO residuals, mass removal rate, drill rate, displacement, and frequency. All tests passed.

Technological Characteristics

Ultrasonic lithotriptor; 100W max output; 19,500–21,500 Hz frequency. Materials: 304 Stainless Steel, with diamond-like carbon coating on select probes. Applied part type: BF. Sterilization: Ethylene Oxide (disposable probes), Prevac Cycle/Prevac Flash Cycle (reusable probes).

Indications for Use

Indicated for fragmentation of urinary tract calculi in the kidney, ureter, and bladder in patients requiring lithotripsy.

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.”

Dear Samradni Patil:

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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.
