Indications for Use
The CyberWand Dual Action Ultrasonic 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 includes generator, ultrasonic transducer with piezoelectric elements, footswitch, and hollow dual probes. Generator drives transducer at 20,400–22,200 Hz; longitudinal waves propagate along probe to target stone; hollow probe design allows simultaneous suction. Used in clinical settings by physicians. Output is mechanical ultrasonic energy for stone fragmentation. Healthcare providers use the device to clear urinary stones, potentially reducing patient morbidity associated with stone disease.

Bench testing only. Verification and validation studies included drill rate, laser vibrometer, surface temperature profile, interface/compatibility, and endurance durability. Sterilization validated via biological indicators for steam and ethylene oxide (ISO 17665-1, ISO 10993-7, ANSI/AAMI/ISO 11135-1). Electromagnetic compatibility verified per EN 60601-1-2, FCC Part 15, and EN 55011.
Technological Characteristics
Electromechanical ultrasonic lithotripter. Piezoelectric transducer driven at 20,400–22,200 Hz. Hollow dual probes for simultaneous suction. Class I equipment, Type BF applied part. Complies with IEC 60601-1, IEC 61847, and EMC standards (EN 60601-1-2, FCC Part 15). Sterilization via prevacuum steam or ethylene oxide.
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.”
Predicate Devices
- CyberWand Dual Probe Lithotripter (K052135)
- CyberWand Hollow Semi-Flexible Ureteral Probe Lithotripter (K102169)

### Performance Data
The safety and effectiveness of the CyberWand Dual Action Ultrasonic Lithotripsy System is determined primarily by confirming that its design and performances conform to the established national and international standards and protocols applicable to lithotripters. The CyberWand Dual Action Ultrasonic Lithotripsy System complies with the requirements of each the standards and protocols discussed below.
#### Performance Considerations
IEC 61847:1998 - Ultrasonics, Surgical Systems - Measurement and Declaration of the Basic Output Characteristics. This international standard defines the parameters which characterize the output and performance of open and closed site ultrasonic surgical systems, and indicates which parameters should be declared. Cybersonics prepared an evaluation report which provides a declaration of output characteristics.
Verification and Validation studies for the Advanced Transducer were performed and documented in a formal report which included results for pre-sterilization and post-sterilization performance tests (Drill Rate Study, Laser Vibrometer Study, Surface Temperature Profile Study, Interface and Compatibility Study, Steam Sterilization and Endurance Durability Study).
{2}------------------------------------------------
The CyberWand Dual Action Ultrasonic Lithotripsy System is classified as Class I equipment with a Type BF applied part that complies with IEC 60601-1.2005 31° Edition.
The purpose of the EMC Directive is to ensure the customer that all standards for manufacturing and operating the electronics of the device safely have been adhered to and followed. The EMC Directive also stipulates that the device will not emit radiation at levels that will interfere with other devices located nearby. Additionally, the EMC Directive will not transmit electro-magnetic surges back into the power grid at frequencies and amplitudes that are above the values listed in the standard.
The evaluation of the CyberWand Dual Action Ultrasonic Lithotripsy System illustrates that the unit meets the emission requirements of the EN 60601-1-2:2007 "Medical Electric Equipment - Part 1, Section 1.2 Collateral Standard: Electromagnetic Compatibility - Requirements and Tests" and with the requirements of IECES-003, Issue 4:2004, FCC Part 15, Subpart B and European Standard EN55011:2007 "Limits and Methods of Measurement of Radio Interference Characteristics of Industrial, Scientific and Medical (ISM) Equipment" including Amendment A1:2010.
The evaluation of the CyberWand Dual Action Ultrasonic Lithotripsy System illustrates that the unit meets the immunity requirements of EN60601-1-2:2007 "Medical Electrical Equipment, Part 1-2: General Requirements for Basic Safety - Collateral Standard: Electromagnetic Compatibility - Requirements and Tests".

## Sterilization Validation Considerations
### Steam Sterilization
Prevacuum steam sterilization technique has been qualified against the ISO 17665-:2006 "Sterilization of Healthcare Products - Moist-Heat - Part 1: Requirements for the Development, Validation and Routine Control of a Sterilization Process for Medical Devices" standard for the Advanced Transducer (USLTA). The results of the biological indicators and inoculated device indicated no spore survivors for three consecutive half cycles. The Cybersonics Advanced Transducer was judged to be effectively sterilized at 132C for a 2 minute Prevac half cycle and zero minute dry time. The cycle conditions are considered adequate to achieve an SAL minimum of 106 at twice the stated exposure time. The thermocouples passed the verification calibration. All positive and negative controls were satisfactory. A dry time of fifteen (15) minutes was successfully validated for the four (4) minute Prevac cycle at 132C for 4 minutes sterilize for the double wrapped transducer.
A steam sterilization study with the CyberWand probes was conducted to determine if exposure of the double wrapped probes would produce the required 10° sterility assurance level using the overkill method as defined in the AAMI-TIR:2004 "Designing, Testing, and Labeling Reusable Medical Devices for Reprocessing in Health Care Facilities: A Guide for Medical Device Manufacturers". The CyberWand probes, doubled wrapped, was judged to be effectively sterilized at 132C for a 2 minute Prevac half cycle and zero minute dry time.
#### Ethylene Oxide Sterilization
The Advanced Transducer was also validated in a 100% ethylene oxide sterilization cycle at 55C for 50 minutes sterilize with twelve (12) hour aeration against the ISO 10993-7:2008 "Biological Evaluation of Medical Devices – Part 7: Ethylene Oxide Sterilization Residuals" standard. The study demonstrated that ethylene oxide (ETO), and its common degradants ethylene chlorohydrin (ECH) and ethylene glycol (EG), are within the allowable limits. The Advanced Transducer also demonstrated a sterility assurance level (SAL) of 10° using the biological indicator (Bacillus atrophaeus ATCC #9372) overkill method.
A study was conducted to validate the sterilization process for the CyberWand Sterile Probe Sets to confirm that the sterility assurance level (SAL) of 10° is obtained. This requalification was performed by Ethox and done in accordance with ANSI/AAMI/ISO 11135-1:2007 Sterilization of healthcare products -Ethylene Oxide - Part 1: Requirements for Development, Validation and Routine Control of Sterilization Process for Medical Devices. This study also included

bioburden testing and EO residual testing to verify the previously validated EO aeration hold time.
#### Conclusion
Cybersonics through its distributor conducts training of the sales representatives and users about the appropriate and proper use of the CyberWand Dual Action Ultrasonic Lithotripsy System. Cybersonics further provides information to the user that is intended to ensure safe and effective use of lithotripsy procedures in its Instructions for Use Manual and other labeling.
