No
The device description focuses on electromechanical principles and ultrasonic technology for stone fragmentation and aspiration. There is no mention of AI or ML in the device description, intended use, or performance studies.
Yes
The device is intended for the fragmentation of urinary tract calculi, addressing a medical condition (kidney stones) for therapeutic purposes.
No
Explanation: The device is intended for the fragmentation and aspiration of calculi, which is a therapeutic function, not a diagnostic one. It actively breaks up kidney stones rather than identifying or characterizing a medical condition.
No
The device description clearly states it is an "electromechanical device" with hardware components like a handpiece, ultrasonic transducer, piezoelectric elements, contact switches, and probes.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, or tissue) to provide information about a person's health.
- Device Function: The ShockPulse-SE Lithotripsy System is an electromechanical device designed to physically fragment urinary tract calculi (kidney stones) within the body. It uses ultrasonic energy and suction to break up and remove stones.
- Intended Use: The intended use is for the fragmentation of urinary tract calculi in the kidney, ureter and bladder. This is a therapeutic procedure performed directly on the patient's internal anatomy, not a diagnostic test performed on a sample outside the body.
The device's function and intended use clearly fall under the category of a therapeutic medical device, not an in vitro diagnostic device.
N/A
Intended Use / Indications for Use
The ShockPulse-SE Lithotripsy System is intended to be used for the fragmentation of urinary tract calculi in the kidney, ureter and bladder.

Device Description
The ShockPulse-SE Lithotripsy System (CYBERWAND II) is the next generation of the CyberWand System. The ShockPulse-SE is an electromechanical device, whose intended purpose is to fragment and aspirate calculi. The hand piece consists of an ultrasonic transducer containing piezoelectric elements which are driven by a generator operating at approximately 21,000 Hz. The transducer is lightweight and incorporates two contact switches that activate Standard Power and High Power generator output. Activation will either require continuous pushing of the button or a double click to latch activation on; a single click of either button would then turn activation off. There are markings near the buttons to indicate function. Suction control is integrated into the transducer housing. With a thumb wheel that can rotate approximately 20 degrees, the flow can be varied from "full" on to "off." There are markings on the transducer to indicate which direction increases and decreases suction flow through the transducer lumen. There are families of probes that function similar to the probes of the current CyberWand System (K120303) by transmitting stress-waves from the transducer to the calculi to break up kidney-stones. Hollow probes permit simultaneous suction. The direct patient-contact material is stainless steel, which is the same material used in the predicate system.

The ShockPulse-SE Lithotripsy System (CYBERWAND II) performs as well as or better than the predicate device. The ShockPulse-SE Lithotripsy System (CYBERWAND II) complies with the requirements of each the standards and protocols discussed below.
The ShockPulse-SE Lithotripsy System (also known as the CyberWand II) was evaluated extensively for performance using bench-top tests and a series of simulated-use animal labs.

§ 876.4480 Electrohydraulic lithotriptor.
(a)
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.(b)
Classification. Class II. The special control for this device is FDA's “Guidance for the Content of Premarket Notifications for Intracorporeal Lithotripters.”
