Intended Use

HESTIA is indicated for generating mammographic images that can be used for screening and diagnosis of breast cancer. HESTIA is intended to be used in the same clinical applications as traditional film/screen systems.

Device Story

HESTIA is a Full-Field Digital Mammography (FFDM) system used for screening and diagnostic imaging of breast tissue. The system comprises an X-ray generator, C-arm compression device, X-ray tube stand, detector, and an acquisition workstation. It captures X-ray signals to produce digital images of internal breast structures, aiding in the detection of micro-calcifications or tumors. Operated by clinicians in medical facilities, the system supports Manual, Semi-auto, and Auto exposure modes. Output images are viewed by radiologists via a DICOM-compatible workstation to inform clinical decision-making regarding breast cancer diagnosis. The device benefits patients by providing high-quality digital diagnostic imaging for early cancer detection.

Clinical Evidence

Clinical image evaluation conducted per FDA Class II Special Controls Guidance for FFDM. Images were reviewed by MQSA-qualified expert radiologists and determined to be of acceptable quality for mammographic usage, demonstrating substantial equivalence to the predicate device. No clinical diagnostic performance metrics (sensitivity/specificity) were reported; evidence relies on image quality assessment.

Technological Characteristics

FFDM system; X-ray generator; C-arm compression; digital detector. Compliance with IEC 60601-1, 60601-1-2, 60601-1-3, 60601-1-6, 60601-2-45. Biocompatibility per ISO 10993-1, -5, -10. Risk management per ISO 14971. Software lifecycle per IEC 62304. Connectivity: DICOM-compliant workstation.

Indications for Use

Indicated for screening and diagnosis of breast cancer in patients requiring mammographic imaging. Used in clinical settings including internal medicine, examination centers, OB/GYN, women's medicine, and breast surgery.

Dear Jiyeon Choi:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and 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 (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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.

| HESTIA is a Full-Field Digital Mammography (FFDM) System for screening, diagnostic on standing or seated patients. The system consists of a control unit with x-ray generator, a compression device(C-arm) with tube housing assembly, and X-ray tube stand, including detector and a console with an operation panel. The HESTIA comes with a variety of compression plates for diagnostic adjunct procedures.

The system is mainly used in internal medicine, examination centers, obstetrics and gynecology, women's medicine, breast surgery, and imaging. Mammography X-rays are used to obtain diagnostic images of the breast's internal structure to diagnose changes more accurately in breast tissue or potential signs of breast cancer, such as micro-calcification or tumors.

HESTIA has three output control mode, Manual mode, Semi-auto mode, and Auto mode.

It is customized and dedicated acquisition workstation and can PACS accessibility with full DICOM capability. | |

Technological Comparison

21 CFR 807.92(a)(6)

HESTIA has identical indications for use and technical characteristic as its predicate device.

The characteristics of HESTIA is identical to those of the predicate device regarding indication for use, patient population, exposure mode, x-ray focal spot size, target material, target angle, kV range, Type of geometry, Software Controlled functions(AEC Calculation, DICOM)

The criteria below are similar or different. but, There is no significant difference between the HESTIA and the predicate device that would adversely affect the use of the product.

- Breast Compression system
- Added filter is similar to that of predicate device, but provides more option than predicate device. Inherent filtration is similar to that of predicate device, but has a lower than predicate device.
- Nominal maximum output power, mAs range, SID, Source to breast support distance are similar to that of predicate device, these values are higher than predicate device or at a value of similar level.
- Sensor material of the detector is different for the predicate device and subject device, but the active area and active array are similar.
- Operating system is similar to that of predicate device.

Even though the predicate device and the subject device differ, the differences are not critical in terms of the diagnostic purposes because the clinical image evaluation demonstrate that the subject devices are substantially equivalent to the predicate device. Therefore, the subject device is substantially equivalent to the predicate device.

[Summary of Clinical data]

A clinical image evaluation in accordance with the Guidance for Industry and FDA Staff: Class II Special Controls Guidance Document: Full Field Digital Mammography System issued on April 4, 2012 (Section 9 Clinical Image Evaluation) was conducted with the HESTIA and determined that the images, reviewed by MQSA qualified expert radiologists, were of sufficiently acceptable quality for mammographic usage and that the images are substantially equivalent to those from predicate device.

[Conclusion]

HESTIA has the same intended use as the predicate device. Any minor differences in the technological characteristics of the subject device when compared to the predicate device have been successfully evaluated through appropriate safety and performance testing which demonstrates that the subject device, when compared to the predicate device, does not raise any new questions of safety and effectiveness. Therefore, HESTIA has been determined to be substantially equivalent to predicate device.
