The AnnuloFlo® System is intended for use in the repair of the human cardiac valve.
The AnnuloFlo® annuloplasty ring is indicated as a reinforcement for repair of the human cardiac mitral valve damaged by acquired or congenital disease, or as a replacement for a previously implanted annuloplasty ring. The annuloplasty ring should be used only in cases where visual inspection confirms that the valve is repairable and does not require replacement.
The AnnuloFlo® System consists of an annuloplasty ring, and a prosthesis of instrumentation provided in a tray to properly size the annulus and implant the annuloplasty ring. The annuloplasty ring is designed to reinforce the native annulus while retaining the native valve apparatus.
The AnnuloFlo® annuloplasty ring employs materials with a long and satisfactory history of use in cardiovascular applications. All materials are non-ferrous, have extensive history in implants and do not present a significant risk during Magnetic Resonance Imaging (MRI). The annuloplasty ring consists of a titanium stiffener ring enclosed in a sewing ring of silicone and knitted polyester fabric.
The mitral AnnuloFlo® annuloplasty ring is kidney shaped. The curved posterior segment of the ring corresponds to the native posterior leaflet. The open segment of the ring corresponds to the anterior leaflet.
I am sorry, but based on the provided text, there is no information about acceptance criteria or a study that proves the device meets any specific criteria. The text is a 510(k) summary and an FDA clearance letter for the AnnuloFlo® Annuloplasty System. It focuses on the device's description, intended use, indications for use, and a comparison to a predicate device for the purpose of demonstrating substantial equivalence for FDA clearance.
The document does not contain details regarding:
- A table of acceptance criteria and reported device performance.
- Sample sizes for test sets or data provenance.
- Number and qualifications of experts for ground truth establishment.
- Adjudication methods.
- MRMC comparative effectiveness studies or effect sizes.
- Standalone algorithm performance.
- Type of ground truth used.
- Sample size for training sets.
- How ground truth for training data was established.
Therefore, I cannot fulfill your request with the given input.
