The device described here is an accessory to imaging devices previously approved. In general, the intended professional application is described as follows: Breast displacement for imaging purposes with the intention of decreasing radiation dose to the breasts and/or improving image quality. The Chrysalis device is reusable and used external to hospital garb; it does not touch the patient's body.
Chrysalis is composed of vinyl-coated polyester, 1/4 inch polyurethane foam headliner, poly-pro webbing, Buckles: 2" side-release plastic buckles
The provided text indicates that the device "Chrysalis" is an accessory to stationary X-ray systems, intended for breast displacement to decrease radiation dose and/or improve image quality. It is a reusable device used externally and does not touch the patient's body.
Based on the provided information, the device is not a software or AI-driven device, and therefore, the typical performance acceptance criteria related to AI or algorithm performance (such as sensitivity, specificity, accuracy, etc.) and the associated studies are not applicable.
The document explicitly states:
- "Assessment of Performance Standards: Not Applicable"
- "Non-Clinical Testing: Biocompatibility testing and safety evaluations were deemed to be unnecessary due to a lack of patient exposure to the device."
This implies that the device is a simple mechanical accessory and its approval is based on its intended use as an accessory to already approved medical imaging devices, rather than on its own diagnostic or AI-driven performance.
Therefore, most of the requested information regarding acceptance criteria and performance studies (like sample size, ground truth, expert opinions, MRMC studies, standalone performance) is not available or relevant for this specific device based on the provided 510(k) summary.
However, I can extract the information relevant to its regulatory approval:
1. A table of acceptance criteria and the reported device performance:
| Acceptance Criteria (Implied by Regulatory Review) | Reported Device Performance (Implied by Regulatory Review) |
|---|---|
| Safe for its intended use as an accessory to stationary X-ray systems. | Biocompatibility and safety evaluations deemed unnecessary due to lack of patient exposure. |
| Functions as an accessory for breast displacement to decrease radiation dose and/or improve image quality. | Device is reusable and used external to hospital garb; it does not touch the patient's body. No explicit performance metrics for dose reduction or image quality improvement are provided in this summary, but its intended function is to facilitate this. |
| Substantially equivalent to legally marketed predicate devices. | Found substantially equivalent to legally marketed predicate devices by the FDA. |
2. Sample size used for the test set and the data provenance: Not applicable, as there were no performance studies of the type described.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set: Not applicable.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance: Not applicable, this is not an AI device.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable, this is not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.): Not applicable.
8. The sample size for the training set: Not applicable.
9. How the ground truth for the training set was established: Not applicable.

Trade/Device Name: Accessory to Stationary X Ray System (Chrysalis) Regulation Number: 21 CFR 892.1650 Regulation Name: Image-intensified fluoroscopic x-ray system Regulatory Class: II Product Code: KPR and MQB Dated: March 3, 2008 Received: March 14, 2008
Dear Mr. Staab:
We have reviewed vour 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, 1796, 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) 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. 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.
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 art the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all 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 letter will allow you to begin marketing your device as described in your Section 510(k) 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 the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Center for Devices and Radiological Health's (CDRH's) Office of Crampliance promo of the following numbers, based on the regulation number at the top of this letter.
