Summary of the K082338 Submission:
The K082338 submission for PolyBone® Granule & Block primarily focuses on demonstrating substantial equivalence to existing legally marketed predicate devices (Kasios TCP, Vitoss Scaffold) by showing similarities in:
- Components: All devices are packed in a container.
- Indication for Use: All devices have the same indication for use: filling bone voids or defects that are not intrinsic to the stability of the bony structure.
- Chemical Similarities: All devices are made up of the ß-Tricalcium phosphate family. (PolyBone® is 99.99% beta-tricalcium phosphate, and 0.01% polyphosphate).
- Performance Properties Similarities: All devices are for filling bone voids or defects that are not intrinsic to the stability of the bony structure.
- Biocompatibility: The device underwent ISO10993-1:2003 testing (cytotoxicity, sensitization, intracutaneous reactivity, systemic toxicity, subchronic toxicity, genotoxicity, and implantation) and was found to be "biologically safe."
The FDA's review concluded that the device is "safe and effective and substantially equivalent to predicate device." This means it does not present new questions of safety or effectiveness compared to the predicate devices, and therefore does not require extensive new clinical studies to prove efficacy against defined acceptance criteria.
