## Intended Use

The trophon Wireless Ultrasound Probe Holder is an accessory to be added to the trophon EPR and trophon2 to allow wireless ultrasound probes to be disinfected. The trophon EPR is designed to provide High-Level Disinfection of ultrasound transducers. The system uses the trophon Disinfectant which is intended to be used exclusively with the trophon EPR device. The trophon Disinfectant is intended for use as a High-Level Disinfectant to be used exclusively with the trophon EPR for the High-Level Disinfection of ultrasound transducers. The trophon EPR is suitable for use in general hospital and health care facilities by trained personnel. The trophon EPR system consists of a multiple use instrument combined with a single use disinfectant, delivered from a multi-dose cartridge. The trophon Disinfectant should be used with the following contact conditions: Minimum Operational Cycle Time: 7 minutes Minimum Concentration: 31.5% Minimum Disinfectant Dose: 1.0 g Minimum Chamber Temperature: 56℃. The trophon2 is designed to provide High-Level Disinfection (HLD) of validated ultrasound transducers. High-Level Disinfection is achieved by surface exposure to a controlled dose of hydrogen peroxide mist delivered to a disinfection chamber contain the ultrasound probe. The trophon2 system consists of a multiple use instrument combined with a single use disinfectant "trophon Sonex-HL", delivered from a multi-dose cartridge. The trophon2 is suitable for use in general hospital and health care facilities by trained personnel. The trophon Sonex-HL should be used with the following contact conditions: Minimum Operational Cycle Time: 7 minutes Minimum Concentration: 31.5% Minimum Disinfectant Dose: 1.0 g Minimum Chamber Temperature: 56°C

## Device Story

Accessory for trophon EPR and trophon2 disinfection systems; enables high-level disinfection (HLD) of wireless ultrasound probes. Device holds wireless probe in place within existing disinfection chamber using cable clamp mechanism. System operates via automated cycle: nebulizer generates hydrogen peroxide mist; mist contacts probe surfaces for specified time, temperature, and dosage; automated aeration removes disinfectant. Used in hospitals/clinics by trained personnel. Output is a disinfected probe ready for immediate clinical use. Benefits include expanded compatibility for wireless transducers while maintaining established HLD efficacy and safety standards.

## Clinical Evidence

No clinical data. Bench testing only, including HLD efficacy (Mycobacterium terrae), residual H2O2 assessment, material compatibility (5000 cycles), temperature monitoring, leak testing, cleaning validation, and human factors validation.

## Technological Characteristics

Accessory for trophon EPR/trophon2. Operates via hydrogen peroxide mist (35% concentration) generated by nebulizer. Includes integrated catalytic destruct system. Software-controlled automated cycle. Complies with IEC 61010-1, IEC 61010-2-040, IEC 61326, IEC 62304, ISO 62366, ISO 10993-1, and ISO 14971.

## Regulatory Identification

A diagnostic ultrasonic transducer is a device made of a piezoelectric material that converts electrical signals into acoustic signals and acoustic signals into electrical signals and intended for use in diagnostic ultrasonic medical devices. Accessories of this generic type of device may include transmission media for acoustically coupling the transducer to the body surface, such as acoustic gel, paste, or a flexible fluid container.

Dear Nancy Kaiser:

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 (the 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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions.

### VIII. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE

The trophon2 and the trophon EPR with the proposed Ultrasound Probe Holder are as safe and as effective in terms of technological characteristics and principles of operation to the predicate device, trophon2 and reference device, trophon EPR without the Ultrasound Probe Holder.

Like the predicate and reference devices, the trophon2 and trophon EPR still achieve HLD by having the probe suspended in their chamber, the Probe Holder is held in place by the cable clamp during high level disinfection to achieve this positioning for a wireless ultrasound probe. During each disinfection cycle, a controlled quantity of hydrogen peroxide mist is generated by a nebulizer and is delivered to the trophon EPR/trophon2 chamber. In the chamber, the mist directly contacts the wired or wireless ultrasound probe covering its surface. Contact occurs for a specified time, temperature, and liquid/mist dosage which determines the germicidal efficacy. The disinfected wired or wireless ultrasound transducer is removed from the chamber and is ready for immediate use. Design verification testing demonstrates that the proposed Wireless Ultrasound Probe Holder meets the product specifications and validation testing confirmed, intended use and user needs continue to be met.
