Intended Use
Rafugen™ DBM is intended for use as a bone void filler in bony voids or gaps of the skeletal system (i.e., pelvis and extremities) not intrinsic to the stability of the bony structure. The voids or gaps may be surgically created defects or defects created by traumatic injury to the bone. Rafugen™ DBM is resorbed/remodeled and is replaced by host bone during the healing process.
Device Description
Rafugen™ DBM is a human bone allograft product containing human DBM (demineralized bone matrix), CMC (carboxymethyl cellulose), Starch and Glycerol. It is intended for use in filling bony voids or gaps of the skeletal system not intrinsic to the stability of the bony structure. Rafugen™ DBM is a ready-to use moldable gel formulation provided pre-filled in syringes of various volumes and is intended for single patient use. It is offered in six volumes: 0.25, 0.5, 1.0, 3.0, 5.0, and 10.0 cc. The Rafugen™ DBM can be either directly applied into the defect from the syringe, using the cap tip, or extruded for molding and insertion into the defect by hand.
More Information

Not Found

No
The summary describes a bone void filler composed of biological and chemical components. There is no mention of software, algorithms, image processing, or any terms related to AI/ML. The performance studies focus on biological and material properties.

Yes
The device is a bone void filler intended to aid in the healing process of bone defects, which is a therapeutic function.

No

Explanation: The device is a bone void filler intended for therapeutic purposes (filling bony voids), not for diagnosing medical conditions.

No

The device description clearly states it is a human bone allograft product containing physical components (DBM, CMC, Starch, Glycerol) and is provided in syringes, indicating a physical, non-software device.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states that Rafugen™ DBM is a "bone void filler in bony voids or gaps of the skeletal system." This describes a device used in vivo (within the body) to facilitate bone healing.
  • Device Description: The description details a "human bone allograft product" in a "moldable gel formulation" for filling bone defects. This is a surgical implant/material, not a diagnostic test performed in vitro (outside the body) on biological samples.
  • Lack of IVD Characteristics: The provided information does not mention any of the typical characteristics of an IVD, such as:
    • Analyzing biological samples (blood, urine, tissue, etc.)
    • Detecting or measuring specific substances (analytes)
    • Providing information for diagnosis, monitoring, or prognosis of a disease or condition

In summary, Rafugen™ DBM is a medical device used for surgical bone repair, not a diagnostic test.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Comparison performance testing in rabbit femoral condyle model.
Osteoinductive potential using an athymic rat assay (ectopic pouch model).
Validation was performed for the Rafugen™ DBM processing to demonstrate inactivation of a panel of model viruses.
The device was tested for material mediated pyrogenicity. The test sample of Rafugen™ DBM was extracted in endotoxin free water, and evaluated by Endosafe PTS™ system. Under the conditions of this study, no endotoxin level showed above 0.5 EU/mL in all five batches. The test extract was judged as non-pyrogenic, and the test sample satisfied the requirements for the absence of pyrogens.
Comparison performance testing conducted in a rabbit critical size femoral defect model demonstrated equivalent bone formation and remodeling.

Rafugen™ DBM is substantially equivalent to the predicate device with respect to materials in that it consists of human demineralized bone matrix (DBM) and an inert resorbable nontissue additive or carrier. The final composition of Rafugen™ DBM was found to be biocompatible and to meet its design specifications. The addition of starch and CMC to the formulation does not raise additional or different questions of safety and effectiveness.

GRAFTON® DBM is indicated for use as a bone graft extender and for use in the posterolateral spine, whereas Cellumed is not seeking those indications for Rafugen™ DBM. The narrower indication does not raise any additional questions of safety and effectiveness.

9. Non-Clinical Performance Data

As part of demonstrating safety and effectiveness of Rafugen™ DBM and in showing substantial equivalence to the predicate device, Cellumed completed a number of tests. In accordance with the "Guidance for Industry and FDA Staff - Class II Special Controls Guidance Document: Resorbable Calcium Salt Bone Void Filler Device,"June, 2003, the following testing has been performed to support substantial equivalence:

  • Chemical and physical properties ●
  • Biocompatibility ●
  • Sterility
  • furthermore Shelf Life
  • Comparison performance testing in rabbit femoral condyle model

6

In addition, the device was tested for osteoinductive potential using an athymic rat assay (ectopic pouch model). Osteoinduction assay results using the athymic rodent assay should not be interpreted to predict clinical performance in human subjects.

Validation was performed for the Rafugen™ DBM processing to demonstrate inactivation of a panel of model viruses.

The device was tested for material mediated pyrogenicity. The test sample of Rafugen™ DBM was extracted in endotoxin free water, and evaluated by Endosafe" PTS™ system. Under the conditions of this study, no endotoxin level showed above 0.5 EU/mL in all five batches. The test extract was judged as non-pyrogenic, and the test sample satisfied the requirements for the absence of pyrogens.

Rafugen™ DBM meets all the requirements for overall design, sterilization, biocompatibility, labeling, and performance. The testing for osteoinductive potential of both devices was demonstrated using a validated athymic rat assay, and comparison performance testing conducted in a rabbit critical size femoral defect model demonstrated equivalent bone formation and remodeling.

10. Clinical Performance Data

There was no clinical testing required to support the medical device as the indications for use is equivalent to the predicate device. The non-clinical testing detailed in this submission supports the substantial equivalence of the device.

11. Statement of Substantial Equivalence

By definition, a device is substantially equivalent to a predicate device when the device has the same intended use and the same technological characteristics as the previously cleared predicate device, or the device has the same intended use and different technological characteristics, but it can be demonstrated that the new device does not raise different questions regarding its safety and effectiveness as compared to the predicate device as a result of the differences in technological characteristics.

It has been shown in this 510(k) submission that the minor differences between the Rafugen™ DBM and the Grafton® DBM predicate device do not raise new questions regarding its safety and effectiveness. The Rafugen™ DBM is therefore determined to be substantially equivalent to the predicate device.

12. Conclusion

The submitted 510(k) demonstrates Rafugen™ DBM is substantially equivalent to the predicate device.
