This submission adds conventional and superfical musculoskeletal imaging to both devices. Both the UF-3500 and the UF-4500 are prescription devices intended to by used by or on the order of a physician or similarly qualified health care professional. Both are intended to be used in a doctor's office and all hospital environments; ER ICU, CCU, OR, etc. These devices are intended to be use on any patient; neonate, pediatric, or adult; where the placement and positioning of the transducer does not interfere with or complicate the treatment of the patient. These devices are not intended for home use.
## Device Story
General-purpose ultrasound systems (UF-3500, UF-4500) utilize linear probes to perform B-Mode imaging. Devices capture acoustic echo data to generate real-time anatomical images of musculoskeletal structures. Operated by physicians or qualified healthcare professionals in clinical settings (doctor's office, hospital, ER, ICU, OR). Output displayed on-screen for clinician review to identify musculoskeletal soft tissues. No hardware or software modifications were made to support the new musculoskeletal imaging indication; acoustic output remains within established Track 1 limits. Benefits include accurate and reproducible visualization of musculoskeletal anatomy to aid clinical assessment.
## Clinical Evidence
Bench testing and clinical evaluation. Skilled sonographers performed imaging using UF-3500 and UF-4500. Images were reviewed by a radiologist to render findings and clinical impressions. Study demonstrated anatomical identification of musculoskeletal soft tissues and confirmed capability for accurate, reproducible imaging.
## Technological Characteristics
General-purpose ultrasound systems using microprocessors. Linear probes (FUT-L104, FUT-L106) used for B-Mode musculoskeletal imaging. Acoustic output complies with Track 1 limits (ISPTA3, MI). No changes to hardware, software, or patient-contact materials. Standalone operation.
## Regulatory 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.

{1}------------------------------------------------
# Description:
The Fukuda Denshi model UF-4500 (K022208) and the model UF-3500 (K955543) are general-purpose ultrasound systems that have been previously found to be substantially equivalent under the Food and Drug Administration's 510(k) process. These devices have not been changed or modified in any way. All software and hardware, all portions of the device that control the acoustic power out are unchanged.
The addition of both conventional and musculoskeletal imaging as intended uses require no changes to the operating instructions.
# Intended Use:
As originally submitted, these devices are intended to be used for applications in fetal, abdominal, intraoperative (defined as the abdominal region and periphery), pediatric, small organ (defined as thyroid, breast and testes), cardiac (UF-4500 only), transrectal, transvaginal (UF-4500 only),, and peripheral vessel scanning. This submission adds conventional and superfical musculoskeletal imaging to both devices.
Both the UF-3500 and the UF-4500 are prescription devices intended to by used by or on the order of a physician or similarly qualified health care professional. Both are intended to be used in a doctor's office and all hospital environments; ER ICU, CCU, OR, etc. These devices are intended to be use on any patient; neonate, pediatric, or adult; where the placement and positioning of the transducer does not interfere with or complicate the treatment of the patient. These devices are not intended for home use.
{2}------------------------------------------------
# Technological Characteristics
The UF-3500 and UF-4500 incorporate microprocessors in a manner similar to the predicate devices. No changes to the hardware or software that control the device or the acoustic output were required to support the claims for musculoskeletal imaging. Conventional and superficial musculoskeletal imaging is possible with linear probes in B-Mode. Patient contact materials have not changed
Both devices' derated acoustic output limits remain below the maximums established for Track 1 devices as listed in the "Information for Manufacturers Seeking Marketing Clearance of Diagnostic Ultrasound Systems and Transducers" issued September 30, 1997, and restated below:
| Use | ISPTA3
(Mw/CM²) | ISPTA3
(Mw/CM²) | MI |
|------------------------|--------------------|--------------------|------|
| Peripheral Vessel | 720 | 190 | 1.9 |
| Cardiac | 430 | 190 | 1.9 |
| Fetal Imaging & Other* | 94 | 190 | 1.9 |
| Ophthalmic | 17 | 28 | 0.23 |
# Testing:
Skilled sonographers using both the UF-3500 and the UF-4500 obtained images. All imaged were reviewed by a radiologist who rendered findings and clinical impression.
# Conclusion:
Based on the anatomical identification of musculoskeletal soft tissues and the diagnostic images obtained from the UF-3500 and the UF-4500, these devises have exhibited the capability of accurately and reproducibly imaging the musculoskeletal structure. Fukuda Denshi has demonstrated through this study that the device is safe and effective in obtaining conventional and superficial musculoskeletal images and is substantially equivalent to the predicate device.

Re: K981404 Fukuda Denshi Ultrasound Scanners Models UF-3500 and UF-4500 Dated: March 23, 1998 Received: April 17, 1998 Regulatory class: II 21 CFR 892.1560/Procode: 90 IYO 21 CFR 892.1570/Procode: 90 ITX
Dear Mr. Geraghty:
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 provisions Act (Act). The general controls provisions of the Act include 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 Fukuda Denshi Ultrasound Scanners Models UF-3500 and UF-4500, as described in your premarket notification:
Transducer Model Number
FUT-L104 (5.0 MHz, 60mm) FUT-L106 (7.5 MHz, 40mm)
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.

Page 2 - David J. Geraghty
Please be advised that the determination above is based on the fact that no medical devices have been demonstrated to be safe and effective for in vitro fertilization or percutaneous umbilical blood sampling, nor have any devices been marketed for these uses in interstate commerce prior to May 28, 1976, or reclassified into class I (General Controls) or class II (Special Controls). FDA considers devices specifically intended for in vitro fertilization and percutaneous umbilical blood sampling to be investigational, and subject to the provision of the investigational device exemptions (IDE) regulations, 21 CFR, Part 812. Therefore, your product labeling must be consistent with FDA's position on this use.
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.
