• Device Name: DIGDOP ULTRASOUND SYSTEM
• Applicant: The Newman Group, LLC
• Product Code: ITX · Radiology
• Decision Date: Apr 8, 2009
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 892.1570
• Device Class: Class 2
• Attributes: 3rd-Party Reviewed

Intended Use

Diagnostic ultrasound imaging or fluid flow analysis of the human body as follows: [Table indicates Fetal application for 2MHz and 3MHz probes, and Peripheral Vascular application for 5MHz and 8MHz probes, all using CWD mode of operation.]

Device Story

DigiDop Ultrasound System consists of a main unit and one of four continuous wave (CWD) probes (2, 3, 5, or 8 MHz). Device operates by emitting continuous wave ultrasound to detect fluid flow or fetal heart activity. Used in clinical settings by healthcare professionals. Output is provided as audio or visual signal for diagnostic assessment of fetal heart rate or peripheral vascular blood flow. System aids clinicians in monitoring fetal health and assessing vascular conditions.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Continuous wave (CWD) ultrasound system. Probes available in 2, 3, 5, and 8 MHz frequencies. System comprises a main unit and a single probe. No specific materials or software algorithms described.

Indications for Use

Indicated for fetal heart beat detection (2MHz, 3MHz probes) and peripheral vascular diagnosis (5MHz, 8MHz probes) in human patients.

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. Job:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and we 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). 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.

This determination of substantial equivalence applies to the following transducers intended for use with the DigiDop Ultrasound System, as described in your premarket notification:

Transducer Model Number

| 2MHz |
|------|
| 3MHz |
| 5MHz |
| 8MHz |

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

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), 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 (OS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

This letter will allow you to begin marketing your device as described in your 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 market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at [phone]. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number [phone] or [phone] or at its Internet address http://www.fda.gov/cdrh/industry/support/index.html

If you have any questions regarding the content of this letter, please contact John Chen at [phone].
