Intended Use

UltraBio, as an in vivo biocompatible and bioexcretable sterile couplant, is intended to replace sterilized transcutaneous scanning gels that are used in surgical procedures, biopsies and similar sterile applications. UltraBio will be used to couple sound waves between the patient and medical imaging transducers during ultrasound imaging procedures. It will be used with transcutaneous and intracavity ultrasound imaging. UltraBio is unit dose packaged, sterilized and intended for use in all diagnostic ultrasound procedures that currently use an ultrasound coupling gel or fluid alone or in combination with a latex sheath and one where sterility and bioelimination are required.

Device Story

UltraBio is a sterile, unit-dose ultrasound coupling agent; functions as a medium to transmit sound waves between patient skin/tissue and diagnostic ultrasound transducers. Used during transcutaneous and intracavity imaging, surgical procedures, and biopsies. Replaces traditional sterile scanning gels; designed for biocompatibility and bioelimination. Applied by clinicians in diagnostic imaging settings. Facilitates clear ultrasound image acquisition by eliminating air gaps between transducer and patient. Benefits patient by maintaining sterility during invasive procedures and ensuring diagnostic image quality.

Clinical Evidence

No clinical data provided; device relies on biocompatibility and sterility validation for substantial equivalence.

Technological Characteristics

Sterile, unit-dose ultrasound coupling agent. Formulated for in vivo biocompatibility and bioelimination. Functions as an acoustic coupling medium. No electronic components, software, or energy sources.

Indications for Use

Indicated for use as a sterile ultrasound coupling medium for transcutaneous and intracavity diagnostic ultrasound imaging procedures, including surgical procedures and biopsies, where sterility and bioelimination are required.

Regulatory Classification

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 Ms. Larson:

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 reguirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act): 21 CFR 1000-1050.

{1}------------------------------------------------

This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please 11 you atter of Compliance at one of the following numbers, based on the regulation number at the top of this letter:

| 21 CFR 876.xxxx | (Gastroenterology/Renal/Urology) | 240-276-0115 |
|-----------------|----------------------------------|--------------|
| 21 CFR 884.xxxx | (Obstetrics/Gynecology) | 240-276-0115 |
| 21 CFR 892.xxxx | (Radiology) | 240-276-0120 |
| Other | | 240-276-0100 |

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97).
