Intended Use

Diagnostic ultrasound imaging or fluid flow analysis of the human body as follows:

Device Story

IMEX StethoDop is a Doppler ultrasound device used for diagnostic imaging or fluid flow analysis. It utilizes a 5 MHz transducer to emit and receive ultrasound signals. The device processes these signals to provide clinical information regarding blood flow or tissue movement. It is intended for use by healthcare professionals in clinical settings. The output is used by clinicians to assess vascular or physiological conditions, aiding in diagnostic decision-making and patient management.

Clinical Evidence

No clinical data provided; clearance based on substantial equivalence and requirement for post-clearance submission of acoustic output measurements.

Technological Characteristics

Diagnostic ultrasound device featuring a 5 MHz transducer. Operates as a Doppler ultrasound system. Subject to 21 CFR 892.1540. Requires compliance with Good Manufacturing Practice (GMP) and Quality System Regulation (21 CFR Part 820).

Indications for Use

Indicated for diagnostic ultrasound imaging or fluid flow analysis of the human body.

Regulatory Classification

Identification

A nonfetal ultrasonic monitor is a device that projects a continuous high-frequency sound wave into body tissue other than a fetus to determine frequency changes (doppler shift) in the reflected wave and is intended for use in the investigation of nonfetal blood flow and other nonfetal body tissues in motion. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.

Re : K973336 IMEX StethoDop™ (Doppler Ultrasound Device) Dated: December 11, 1997 December 17, 1997 Received: Regulatory class: İI 90 JAF 21 CFR 892.1540/Procode:

Dear Mr. Wagner:

We have reviewed your section 510(k) 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 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. You may, therefore, market the device, subject to the general controls The general controls provisions of the Act include provisions Act (Act). requirements for registration, listing of devices, good manufacturing practices, labeling, and prohibitions against misbranding and adulteration.

This determination of substantial equivalence applies to the following transducers intended for use with the IMEX StethoDop™, as described in your premarket notification:

## Transducer Model Number

5 MHz

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 895. A substantially equivalent determination assumes compliance with the Good ……… Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General (GMP) regulation (21 CFR Part 820) and that, through periodic QS inspections, the FDA will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, the Food and Drug Administration (FDA) may publish further announcements concerning your device in the Federal Register Please note: this response to your premarket notification does not affect any obligation you may have under sections 531 and 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.

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.
