PhotoFix is indicated for the following uses: intracardiac repair, suture line buttressing, pericardial closure, and vascular repair and reconstruction (for example: the carotid, iliac, femoral, and tibial blood vessels and arteriovenous access revisions).
The PhotoFix® Decellularized Bovine Pericardium ("PhotoFix") is a cardiovascular patch that is prepared from bovine pericardium, stabilized using dye-mediated photooxidation, processed using ethylene oxide, and sterilized using aseptic processing techniques. The photooxidation process creates crosslinks in the bovine tissue. No aldehyde chemistry is used during any phase of manufacturing including the tissue fixation or sterilization processes. PhotoFix is intended for single use only and cannot be resterilized. PhotoFix is supplied sterile in a sealed container with 22% buffered ethanol solution. Rinsing of the pericardium prior to implantation is not required.
This document is a 510(k) premarket notification for a medical device called PhotoFix® Decellularized Bovine Pericardium. It describes the device and claims substantial equivalence to a previously marketed device (K172085).
However, the provided text does not contain any information about acceptance criteria or a study that proves the device meets specific performance criteria, especially in the context of an AI/ML powered device. The document is a traditional medical device submission for a physical implant, not an AI/ML algorithm.
Therefore, I cannot fulfill your request for:
- A table of acceptance criteria and the reported device performance.
- Sample size used for the test set and data provenance.
- Number of experts used to establish ground truth.
- Adjudication method.
- MRMC comparative effectiveness study.
- Standalone performance.
- Type of ground truth used.
- Sample size for the training set.
- How ground truth for the training set was established.
This document focuses on the substantial equivalence of a modified physical device (a new packaging size for an existing bovine pericardium patch) to a predicate device, based on non-clinical testing related to packaging integrity and shelf-life, not clinical performance metrics or AI/ML algorithm validation.

Dear Ms. Emerick:
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 (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 located 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.
{1}------------------------------------------------
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 the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/CombinationProducts/GuidanceRegulatoryInformation/ucm597488.html; good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm.
For comprehensive regulatory information about mediation-emitting products, including information about labeling regulations, please see Device Advice (https://www.fda.gov/MedicalDevices/DeviceRegulationandGuidance/) and CDRH Learn (http://www.fda.gov/Training/CDRHLearn). Additionally, you may contact the Division of Industry and Consumer Education (DICE) to ask a question about a specific regulatory topic. See the DICE website (http://www.fda.gov/DICE) for more information or contact DICE by email (DICE@fda.hhs.gov) or phone (1-800-638-2041 or 301-796-7100).

Device Description
The PhotoFix® Decellularized Bovine Pericardium ("PhotoFix") is a cardiovascular patch that is prepared from bovine pericardium, stabilized using dye-mediated photooxidation, processed using ethylene oxide, and sterilized using aseptic processing techniques. The photooxidation process creates crosslinks in the bovine tissue. No aldehyde chemistry is used during any phase of manufacturing including the tissue fixation or sterilization processes.
PhotoFix is intended for single use only and cannot be resterilized. PhotoFix is supplied sterile in a sealed container with 22% buffered ethanol solution. Rinsing of the pericardium prior to implantation is not required.
{4}------------------------------------------------
Indications for Use
PhotoFix is indicated for the following uses: intracardiac repair, great vessel repair, suture line buttressing, pericardial closure, and vascular repair and reconstruction (for example: the carotid, iliac, femoral, and tibial blood vessels and arteriovenous access revisions).
Comparison to Predicate Device
PhotoFix Decellularized Bovine Pericardium is serving as its own predicate device. PhotoFix Decellularized Bovine Pericardium is substantially equivalent to the currently marketed device (K172085) in regards to intended use, processing method, sterilization method and technological characteristics with the exception of the 8x14cm patch configuration which is the focus of this Special 510(k) submission. The 8x14cm patch configuration will be packaged in a 250mL final packaging bottle; all other PhotoFix patch configurations are packaged in a 125mL final packaging bottle.
A risk analysis has been performed and all design verification and design validation activities have been identified and completed in conformance with design control requirements. Based on the qualification activities of the new 250mL bottle, the shelf life requirement of the 8x14cm patch configuration will be identified as a minimum of 1 year.
Non-Clinical Testing
In order to demonstrate substantial equivalence between the existing 125mL bottle and the proposed 250mL bottle, the following testing was performed:
- Simulated Distribution testing followed by Bacterial Aerosol Challenge testing
- 트 Accelerated Aging Shelf Life testing followed by Bacterial Aerosol Challenge testing
Conclusion:
PhotoFix Decellularized Bovine Pericardium is substantially equivalent to the predicate device currently on the market (K172085).
