Indications for Use
Diagnostic Ultrasound imaging or fluid flow analysis of the human body as follows: The Ecton Lynx with Pulsed Wave Doppler is intended for the previously cleared clinical indications of adult and pediatric cardiac, intraoperative cardiac, peripheral vascular, abdominal, fetal, pediatric and neonatal cephalic imaging.
Device Story
Portable digital ultrasound system; transmits/receives ultrasound waves via piezoelectric transducers; converts reflected sound waves into electrical signals; processes signals for display as Doppler spectrum analysis. Used in clinical settings by healthcare professionals for diagnostic imaging. Provides real-time display of thermal and mechanical acoustic indices (AIUM/NEMA 1996) to assist ALARA-compliant scanning. Output aids clinicians in diagnostic decision-making for cardiac, vascular, and fetal assessments. Does not support combined scanning modes.
Clinical Evidence
Bench testing only. No clinical data provided. Substantial equivalence supported by comparison of technological characteristics, acoustic output measurements, and adherence to AIUM/NEMA 1996 standards for thermal and mechanical indices.
Technological Characteristics
Portable digital ultrasound system; piezoelectric transducer material; modes include 2D, M-Mode, Color Flow, Doppler Tissue Imaging, Continuous Wave, and Pulsed Wave Doppler. Conforms to AIUM/NEMA 1996 for thermal/mechanical indices. Acoustic output: ISPTA max 720 mW/cm², Mechanical Index max 1.9. No combined scanning modes.
Indications for Use
Indicated for diagnostic ultrasound imaging or fluid flow analysis in adult and pediatric patients, including fetal, abdominal, intraoperative cardiac, peripheral vascular, and neonatal cephalic applications. Not intended for ophthalmic 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.

#### 4 ) Device Description
The Ecton Lynx Ultrasound System is a general purpose and cardiac diagnostic ultrasound system. It is a highly portable digital system. Its function is to transmit and acquire ultrasound image data and display it on a monitor. The system has been cleared to operate in 2D, M-Mode, Color Flow Doppler, Doppler Tissue Imaging, and Continuous Wave Doppler modes (K982800).

#### Indications for Use / Intended Use 5 )
The Ecton Lynx with Pulsed Wave Doppler is intended for the previously cleared clinical indications of adult and pediatric cardiac, intraoperative cardiac, peripheral vascular, abdominal, fetal, pediatric and neonatal cephalic imaging.
#### ୧ ) Characteristics Technological
The Ecton Lynx with Pulsed Wave Doppler operates in a manner that is identical to the previously cleared version of the system and the predicate devices. Piezoelectric material in the transducer is used as an ultrasound generator to transmit sound waves into the body. Reflected sound waves are

received by the transducer and converted into electrical signals that are processed and displayed as as a Doppler spectrum analysis.
The Lynx conforms to the Standard for Real-Time Display of Thermal and Mechanical Acoustic Indices on Diagnostic Ultrasound Equipment (AIUM/NEMA 1996) for the on-screen display of mechanical and thermal indices. This feature provides the user with information on potential thermal and cavitation bioeffect mechanisms. A user education program provides information instructing users on machine settings and scanning techniques that allow for examinations to be conducted in accordance with the ALARA (as low as reasonably achievable) principle.
The acoustic output limits of the Lynx with Pulsed Wave Doppler are the same as the previously cleared version of the system and the predicate Track 3 devices:

Dear Mr. Mosenkis:
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 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 Lynx Diagnostic Ultrasound System with Pulsed Doppler as described in your premarket notification:
Transducer Model Number(s):
2.7 MHz External 5.0 MHz External 5.0 MHz Biplane Transesophageal 5.0 MHz Monoplane Transesophageal
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 (OS) 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.

Page -2 - Mr. Mosenkis
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 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4591.
