It is placed on the patient's skin or on the transducer prior to initiating an ultrasound examination. ## Device Story Ultra/Phonic® Scanning Gel is an aqueous, non-sterile ultrasound conducting medium; applied to patient skin or transducer surface prior to ultrasound examination. Gel eliminates air at contact interface; provides lubrication; creates acoustic pathway for sound wave transmission and echo reception. Scanner processes received echoes to generate diagnostic/therapeutic images for healthcare professional review. Used in hospital settings; applied by clinicians. Formulation is salt-free, water-soluble, sheer-thinning; resists decomposition from body heat/perspiration; maintains acoustic coupling performance. ## Clinical Evidence No clinical data. Bench testing only. Acoustic properties (sound velocity, density, impedance, attenuation) compared to predicate; results virtually identical. Antimicrobial effectiveness testing (USP <51>) passed for bacteria, yeasts, and molds. Biocompatibility testing (ISO 10993-10) confirmed non-sensitizing and non-irritating. In vitro cytotoxicity testing (ISO 10993-5:2009) confirmed non-cytotoxic. ## Technological Characteristics Aqueous, water-soluble high molecular weight polymer gel. Salt-free, alcohol-free, formaldehyde-free, perfume-free. pH 6.25 ± 0.25. Viscosity 200,000 ± 100,000 CPS. Sheer-thinning behavior. Packaged in polyethylene containers (bottles, tubes, Cubitainers). Non-sterile. No energy source; used with external ultrasound transducers. ## 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. ## Predicate Devices - Sonishield™ 100 Antimicrobial Ultrasound Gel ([K151070](/device/K151070.md)) ## Reference Devices - Ecogel 100 Ultrasound Gel ([K961757](/device/K961757.md)) - Konix Ultrasound Gel ([K101952](/device/K101952.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

DEVICE DESCRIPTION Ultra/Phonic® Scanning Gel is an aqueous, non-sterile ultrasound conducting medium for use during non-invasive ultrasonic medical procedures. It is placed between the ultrasound transducer and the patient, eliminating air at the contact surface while providing lubrication. This provides an acoustic pathway between the transducer and the skin. This uninterrupted pathway allows the transducer to send sound waves which enter the body, and to receive echoes from tissues and structures without unexpected interference. When the echoes are received by the scanner, it analyzes them to determine how strong they are, and how long they took to be received after transmission. That information is then processed and outputted to a display as an image which is used for diagnostic and therapeutic purposes by health care professionals. It is packaged in 4L Cubitainers, 5L Cubitainers, and 250 mL bottles. # Major characteristics include: - Non-sensitizing, non-irritating - Water soluble, non-staining, and easily cleanable - Does not contain oil or fatty matter - Has no odor - . Salt (Sodium Chloride) Free - Does not damage the probe - pH level is 6.25 ± 0.25 @ 25°C - Resists thinning and decomposition when exposed to perspiration and body heat - Sheer thinning gel is easy to apply, but doesn't run or drip - Relatively low viscosity, in conjunction with sheer thinning behavior, gives the product the feel and lubricity of oil while providing the performance characteristics and ease of use of an aqueous gel # V. INDICATIONS FOR USE The Indications for Use statement is as follows: Ultra/Phonic® Scanning Gel is intended for general use as a non-sterile transmission media for acoustically coupling a transducer to a human body surface during external therapeutic and diagnostic ultrasound imaging procedures. It is placed on the patient's skin or on the transducer prior to initiating an ultrasound examination. The product is indicated for prescription use only.

PERFORMANČE DATA The following performance data was provided in support of the substantial equivalence determination. # Non-clinical performance # Acoustic: Ultra/Phonic® Scanning Gel was evaluated for its acoustic performance. Results indicate that the acoustic properties of the gel are: - 1. Virtually identical to that of human skin. - 2. Similar to other coupling gels commonly used in the United States. The acoustic properties of Ultra/Phonic® Scanning Gel and Sonishield™ 100 Antimicrobial Ultrasound Gel are as follows: | Property | Ultra/Phonic®

frequency, a/f (dB/(cm-MHz)) | $0.06 + 0.01116 f^{1.3706}$ | $0.04 \pm 0.0042 f$ | The acoustic properties of the predicate gel and Ultra/Phonic® Scanning Gel are virtually identical. Although the analysis was conducted at different temperatures, both are well within the range of temperatures encountered during clinical use (72.5°F - 80°F). Such variations in temperature do not induce more than small changes in the listed acoustic properties, too small to alter performance, or cast doubt upon the conclusions of this comparison.

Yeasts and molds (Aspergillus brasiliensis ATCC 16404, Candida albicans ATCC 10231) did not increase from initial counts, and in fact considerably decreased. # Animal tests: Biocompatibility (ISO 10993-10) testing was conducted for Skin Irritation and Skin Sensitization. Conclusions from these studies: Ultra/Phonic® Scanning Gel was found to be non-sensitizing and nonirritating. # In Vitro Cytotoxicity: Cytotoxicity (ISO 10993-5:2009) testing was conducted. Conclusion from this study: The test article meets the requirement of the test as per The International Organization for Standardization (ISO 10993-5 Biological Evaluation of Medical Devices – Part 5: Tests for the In Vitro Cytotoxicity, Reference Number ISO 10993-5:2009), and is not considered cytotoxic. # VIII.
