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.
§ 870.3470 Intracardiac patch or pledget made of polypropylene, polyethylene terephthalate, or polytetrafluoroethylene.
(a)
Identification. An intracardiac patch or pledget made of polypropylene, polyethylene terephthalate, or polytetrafluoroethylene is a fabric device placed in the heart that is used to repair septal defects, for patch grafting, to repair tissue, and to buttress sutures.(b)
Classification. Class II (performance standards).
