Indications for Use
An ultrasound pulsed echo imaging system is intended to project a pulsed sound beam into body tissue to determine the depth of location of the tissue interfaces and to measure the duration of an acoustic pulse from the transmitter to the tissue interface and back to the receiver. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts and accessories. The device is indicated for use as an adjunct to mammography for B-mode ultrasonic imaging of a patient's breast when used with an automatic scanning linear array transducer or a handheld transducer. The device is not intended to be used as a replacement for screening mammography.
Device Story
Automated Breast Ultrasound System (ABUS) provides automated ultrasound imaging of breast tissue; serves as adjunct to mammography for radiologist review. System inputs include acoustic pulse data from automatic scanning linear array transducers or conventional handheld transducers. Device transforms acoustic echoes into B-mode images for visualization. Used in clinical settings by healthcare professionals. Output allows clinicians to correlate ultrasound findings with mammograms, aiding diagnostic assessment of breast tissue. Benefits include improved diagnostic capability for breast imaging as a supplement to standard mammography.
Clinical Evidence
No clinical data provided. Substantial equivalence is supported by bench testing, integration testing, and verification and validation activities.
Technological Characteristics
Diagnostic ultrasound system utilizing pulsed echo imaging. Supports automatic scanning linear array transducers (L9-5XW, L10-5XW, L12-6) and handheld transducers (L15-6). Features include B-mode imaging, harmonic imaging, and spatial compounding. System includes signal analysis and display equipment. Software controls transducer operation.
Indications for Use
Indicated for B-mode ultrasonic imaging of the breast as an adjunct to mammography in patients requiring supplemental breast imaging. Not intended as a replacement for screening mammography.
Regulatory Classification
Identification
An ultrasonic pulsed echo imaging system is a device intended to project a pulsed sound beam into body tissue to determine the depth or location of the tissue interfaces and to measure the duration of an acoustic pulse from the transmitter to the tissue interface and back to the receiver. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.
Special Controls
*Classification.* Class II (special controls). A biopsy needle guide kit intended for use with an ultrasonic pulsed echo imaging system only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.

#### A. Legally Marketed Predicate Device
The Company believes that the modified ABUS is substantially equivalent to the previously cleared U-Systems - ABUS (K052355), as well as the Siemens - Antares DUS (K023720).
The intended use and the technological characteristics of the device are the same as the predicate devices.
### B. Device Description
The ABUS system with automated ultrasound imaging of the breast, gives the radiologist a cost-effective solution for reviewing the ultrasound images with the corresponding mammogram.
The modification to the sponsor's predicate device consists of the addition of the accessory of a conventional handheld ultrasound transducer, and modification to the software to control the new transducer.

#### C. Intended Use
General Indication for Use
An ultrasound pulsed echo imaging system is intended to project a pulsed sound beam into body tissue to determine the depth of location of the tissue interfaces and to measure the duration of an acoustic pulse from the transmitter to the tissue interface and back to the receiver. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts and accessories.
#### Specific Indications for Use
The device is indicated for use as an adjunct to mammography for B-mode ultrasonic imaging of a patient's breast when used with an automatic scanning linear array transducer or a handheld transducer. The device is not intended to be used as a replacement for screening mammography.
### D. Substantial Equivalence
The ABUS System modification is substantially equivalent to the sponsor's original ABUS device (K052355) as well as the Sicmens Antares DUS (K023720. The intended usc and the technological characteristics of the device are the same as the predicate devices.
### E. Performance data
The ABUS System will successfully complete integration testing, beta testing, and verification and validation prior to market release.

Re: K080930
Trade/Device Name: Automated Breast Ultrasound System (ABUS) Regulation Number: 21 CFR 892.1560 Regulation Name: Ultrasonic pulsed echo imaging system Regulatory Class: II Product Code: IYO and ITX Dated: June 27, 2008 Received: June 30, 2008
Dear Ms. Scott:
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 Automated Breast Ultrasound System (ABUS), as described in your premarket notification:
Transducer Model Number
L9-5XW MHz L10-5XW MHz L12-6 MHz L15-6 MHz
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
{3}------------------------------------------------
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 (240) 276-0120. Also, please note the regulation entitled. "Misbranding by reference to premarket notification" (21CFR Part 807.97).
