General Ultrasound Scanner Device Description

The Voluson C530D scanner (K940942) is a general purpose, mobile, software controlled, diagnostic ultrasound system. Its function is to acquire ultrasound data and to display the data as B-mode, Mmode, Color-Flow Doppler, Pulsed (PW) Doppler and Power Angio Doppler (K974813), or as a combination of these modes. The Voluson C530D also gives the operator the ability to measure anatomical structures and offers analysis packages that provide information that is used to make a diagnosis by competent health care professionals. The Voluson C530D has real time acoustic output display with two basic indices, a mechanical index and a thermal index, which are both automatically displayed.

#### Transducer S-VNA 5-8(B) Device Description 5)

The S-VNA 5-8(B) transducer is a mechanically steered curved array (Volume) probe. This is identical to the previously cleared (K940942) endocavitary S-VDW 5-8 probe, with the same materials, same acoustic module, and the same technical performance. The primary mechanical difference with the endocavity S-VDW 5-8 probe is the modified (shorter) shaft, designed to allow use on the outer surface of the body.

The VOLUSON® Neonatal transducer S-VNA5-8(B) is an electronic wideband sector-transducer with a center frequency of 6.5 MHz and with switchable scan angles. The direction of insonation is forward in relation to the transducer's longitudinal axis. This device is a hand-held, 128 element, curved linear array probe. In addition to B-Mode and M-Mode, this probe can be operated in steerable pulsed Doppler, Color Doppler, Color Power Angio Doppler, and 3D Imaging. Similar to the S-VDW 5-8 transducer, the S-VN A5-8(B) also allows the performance of a 3D volume scan by internally sweeping the array in a lateral direction, automatically upon a key press. The images thus obtained from sectional planes perpendicular to each other can be displayed synoptically on the screen. This device is intended for use with the Combison/Voluson C530D Diagnostic Ultrasound Scanner for transcutaneous imaging as an aid in the detection and assessment of physical and functional abnormalities using established diagnostic criteria. The patient contact materials for biological evaluation that are brought into contact with patients are exactly the same as those of the previously cleared Combison/Voluson C530D Diagnostic Ultrasound System and Transducers (K940942/K974813), specifically the S-VDW 5-8 Endocavity transducer.

The S-VNA 5-8(B) Ultrasound Transducer has been designed to meet the following electromechanical safety standards:

- EN 60601-1 (IEC 601-1,) European Norm, Medical Electrical Equipment .
- . UL 2601-1, Underwriters Laboratories Standards, Medical Electrical Equipment
- C22.2 No. 601.1, Canadian Standards Association, Medical Electrical Equipment .

{2}------------------------------------------------

- . CEI/IEC 1157:1992, International Electrotechnical Commission, Requirements for the declaration of the acoustic output of medical diagnostic ultrasonic equipment
- EN 60601-1-2 (IEC 601-1-2,) European Norm, Collateral Standard: Electromagnetic compatibility .
- Compliant with the European Medical Device Directive Certificate issued by TUV. .

#### 5) Intended Use:

The S-VNA 5-8(B) Ultrasound Transducer intended uses as defined FDA guidance documents are:

- . Neonatal Cephalic
- . Fetal
- Pediatric and Neonatal Abdominal .

Typical examinations performed using this transducer are:

- General abdominal studies including organ surveys, assessment, and retro-peritoneal cavity studies. .
- . Pediatric scans of organs and bony structures.
- Neonatal head studies. .
- Biopsy guidance for tissue or fluid sampling. ●

#### Technological Characteristics: 6)

This device operates identical to the predicate devices in that piezoelectric material in the transducer is used as an ultrasound source to transmit sound waves into the body. Sound waves are reflected back to the transducer and converted to electrical signals that are processed and displayed as a 2D and M-mode, Spectral Doppler, Power Doppler, Power Doppler, and 3D images. Scanhead patient contact materials are biocompatible.

The device's acoustic output limits are:

All Applications:

| | (Maximum Range) |
|-------|-----------------|
| ISPTA | 720 mW/cm2 |
| MI | 1.9 |

The limits are the same as predicate Track 3 devices.

Re: K984639 Trade Name: S-VNA 5-8 (B) Diagnostic Ultrasound Transducer Regulatory Class: II 21CFR 892 1570/Procode: 90 ITX Dated: June 4, 1999 Received: June 8, 1999

Dear Mr. Leiker:

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 transducer intended for use with the Voluson C530D Ultrasound System, as described in your premarket notification:

Transducer Model Number

S-VNA 5-8 (B) Diagnostic Ultrasound Transducer

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

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

# Page 2 - Mr. Bob Leiker

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.
