Intended Use

The Digi-Lite TCD device is intended for use in the non-invasive evaluation of intracranial and extracranial vascular flow velocity irregularities in adults and in children. It is not intended for fetal use. It is not intended for neonatal use.

Device Story

Digi-Lite TCD is a PC-based ultrasound system for non-invasive vascular flow velocity evaluation. System inputs include ultrasound signals captured via 1, 2, 4, or 8 MHz probes. Hardware includes a Doppler card with FPGA for timing/basic signal processing and a DSP chip for general control and digital signal processing algorithms. The system translates received signals into Doppler shift frequencies. Output is displayed on a 15" TFT touch screen. Operated by clinicians in clinical settings. Output assists in identifying vascular flow irregularities. Benefits include non-invasive diagnostic capability for intracranial and extracranial vasculature.

Clinical Evidence

Bench testing only. Testing included software validation, electromagnetic compatibility, electrical safety, acoustic output testing, clinical measurement accuracy, Doppler sensitivity, and temperature rise estimation per FDA guidance (September 1997). Results demonstrated the device performs according to specifications.

Technological Characteristics

PC-based platform (Windows XP embedded, Pentium M processor). Includes Doppler card with FPGA and DSP for signal processing. Transducers: 1 MHz, 2 MHz, 4 MHz, 8 MHz PW/CWD. Connectivity: USB, RS232, LAN 10/100 RJ-45. Display: 15" TFT color SVGA (1024x768).

Indications for Use

Indicated for non-invasive evaluation of intracranial and extracranial vascular flow velocity irregularities in adults and children. Contraindicated for fetal and neonatal use.

Regulatory Classification

Identification

An ultrasonic pulsed doppler imaging system is a device that combines the features of continuous wave doppler-effect technology with pulsed-echo effect technology and is intended to determine stationary body tissue characteristics, such as depth or location of tissue interfaces or dynamic tissue characteristics such as velocity of blood or tissue motion. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.

#### Dear Ms. Stein:

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 Digi-Lite TCD Device, as described in your premarket notification:

#### Transducer Model Number

1 MHz PW 2 MHz PW

4 MHz PW 8MHz

Image /page/3/Picture/14 description: The image shows a circular logo with the letters "FDA" in a stylized font at the center. Above the letters, the years "1906 - 2006" are printed. Below the letters, the word "Centennial" is written in a cursive font. The logo is surrounded by a circular border with text, and there are three stars at the bottom of the logo.

{4}------------------------------------------------

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 (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.

This determination of substantial equivalence is granted on the condition that prior to shipping the first device, you submit a postclearance special report. This report should contain complete information, including acoustic output measurements based on production line devices, requested in Appendix G, (enclosed) of the Center's September 30, 1997 "Information for Manufacturers Seeking Marketing Clearance of Diagnostic Ultrasound Systems and Transducers." If the special report is incomplete or contains unacceptable values (e.g., acoustic output greater than approved levels), then the 510(k) clearance may not apply to the production units which as a result may be considered adulterated or misbranded.

The special report should reference the manufacturer's 510(k) number. It should be clearly and prominently marked "ADD-TO-FILE" and should be submitted in duplicate to:

> Food and Drug Administration Center for Devices and Radiological Health Document Mail Center (HFZ-401) 9200 Corporate Boulevard Rockville, Maryland 20850

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
