Intended Use

VivoSonic™ will be used during invasive medical diagnostic ultrasound imaging to couple sound waves between patient and medical imaging electronics and to lubricate the insertion and passage of imaging devices, such as ultrasound transducers and endoscopes. VivoSonic™ is intended for use in conjunction with transcutaneous ultrasound image guided biopsy and aspiration, intraoperative ultrasound imaging, endocavity ultrasound imaging and opthalmic ultrasound imaging. VivoSonic™ is unit dose packaged, sterilized and intended for use in all diagnostic ultrasound procedures which currently use and ultrasound coupling gel or fluid alone or in combination with a latex, non-latex, polyurethane or polyethylene transducer cover where sterility and/or in vivo biocompatibility are required.

Device Story

VivoSonic™ is a sterile, in vivo biocompatible ultrasound coupling medium and lubricant. It functions by facilitating acoustic coupling between the patient's body and the ultrasound transducer, while simultaneously providing lubrication for the insertion and passage of imaging devices such as endoscopes and transducers. The device is supplied in unit-dose packaging to maintain sterility. It is intended for use by clinicians in various diagnostic ultrasound settings, including invasive procedures like biopsies, aspirations, intraoperative, endocavity, and ophthalmic imaging. By ensuring effective sound wave transmission and reducing friction during device insertion, it supports accurate diagnostic imaging and patient comfort during invasive ultrasound-guided procedures.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on the device's intended use, formulation, and performance characteristics being equivalent to legally marketed predicate devices.

Technological Characteristics

Sterile, in vivo biocompatible ultrasound coupling gel/fluid. Unit dose packaging. Formulated for acoustic coupling and lubrication. Compatible with latex, non-latex, polyurethane, and polyethylene transducer covers.

Indications for Use

Indicated for use during invasive diagnostic ultrasound imaging procedures, including transcutaneous image-guided biopsy/aspiration, intraoperative, endocavity, and ophthalmic imaging. Used to couple sound waves between patient and transducer and to lubricate imaging devices. Intended for procedures requiring sterility and in vivo biocompatibility, including use with transducer covers.

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 Mr. Bonner:

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 requirements 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 (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898.
