The description focuses on the material composition and physical properties of a bone graft substitute, with no mention of AI/ML capabilities or data processing.
No
The device is described as a bone void filler and graft extender, which assists in bone repair and growth, but it does not directly treat a disease or condition in the way a therapeutic device would (e.g., drug delivery, radiation therapy).
No
The device, ALLOMATRIX® Custom, is described as a bone graft extender and bone void filler, used to be gently packed into bony voids or gaps. Its intended use is therapeutic (filling voids), not for diagnosing conditions or diseases. The performance studies evaluate its effectiveness in promoting fusion and its comparison to autograft, which are measures of therapeutic outcome, not diagnostic capability.
No
The device description clearly states it is a kit containing powder, CBM chips, mixing solution, and tools, which are physical components, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is for filling bony voids or gaps in the skeletal system as a bone graft extender or bone void filler. This is a therapeutic or structural purpose, not a diagnostic one.
- Device Description: The description details a kit for creating a putty to be placed in bone. This aligns with a surgical or therapeutic device, not a diagnostic test performed on samples outside the body.
- Lack of IVD Characteristics: There is no mention of analyzing samples (blood, tissue, etc.) to provide diagnostic information about a patient's condition. The device itself is the treatment or structural support.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.

Intended Use / Indications for Use
ALLOMATRIX® Custom is indicated only for bony voids or gaps that are not intrinsic to the stability of the bony structure. ALLOMATRIX® Custom is intended to be gently packed into bony voids or gaps of the skeletal system as a bone graft extender (spine) and as a bone void filler in the extremities and pelvis. These defects may be surgically created osseous defects or osseous defects created from traumatic injury to the bone.

Device Description
ALLOMATRIX® Custom Putty is provided in the form of a kit with a premeasured powder and CBM chips, premeasured mixing solution, and the tools necessary to mix the components. After the powder is hydrated using all the mixing solution supplied in the kit (or BMA and local bone when used in the spine), the resultant putty can then be handled and placed in the appropriate bone voids. This product is supplied sterile for single patient use.

Summary of Performance Studies
Clinical performance of the subject device mixed with BMA and local bone was evaluated by a comparison of radiographic outcomes (i.e., Lenke fusion score), SF-36 subjective questionnaire, Oswestry disability questionnaire, Visual Analog Scale for back and leg pain, and adverse event profile compared to autograft iliac crest bone. This study demonstrated equivalency between the subject device and predicate autologous iliac crest bone where lumbosacral fusion is indicated.

ﻧ SUBSTANTIAL EQUIVALENCE INFORMATION
ALLOMATRIX® Custom Putty was found to be substantially equivalent to the predicate devices. The safety and effectiveness of ALLOMATRIX® Custom Putty is adequately supported by the substantial equivalence information, materials data, and testing results provided within this Premarket Notification.
Osteoinductivity Potential
F.ach lot of Demineralized Bone Matrix (DBM) incorporated into ALLOMATRIX® Custom is evaluated in vitro using a surrogate cell-based assay . The bioassay measures the proliferation of Saos human osteosarcoma cells in the presence of human DBM compared to positive and negative controls (osteoinductivity index)'. Results from this bioassay were correlated to the athymic rat models and to clinical results of assayed DBM alone'.
Or
Each lot of DBM incorporated into ALLOMATRIX® Custom is assayed in vitro for a native protein as a surrogate test marker for osteoinductive potential . Results from this immunoassay were correlated to the athymic rat model for the DBM alone and the ALLOMATRIX® Putty3. Although only one native protein is used as the test marker, it is the combination of various proteins that is responsible for its osteoinductive potential.
Testing each lot of DBM with this cell-based bioassay' or immunoassay' assures that only DBM with osteoinductive potential is used in the ALLOMATRIX® Custom. The combination of DBM, Cancellous Bone Matrix (CBM), and binding medium has not been evaluated for osteoinductivity; therefore, it is unknown to what extent the formulation components may alter the osteoinductive character of the DBM. Additionally, it is unknown how osteoinductivity of the DBM component, measured via the in vitro bioassay or immunoassay', will correlate with human clinical performance of ALLOMATRIX® Custom.

Viral Inactivation Validation
The method for processing the DBM and CBM contained in ALLOMATRIX® Custom Putty was evaluated for its viral inactivation potential. A panel of model potential human viruses representing various virus types, sizes, shapes, and genomes were evaluated. The viral inactivation testing demonstrated suitable viral inactivation potential of the processing method for a wide spectrum of potential human viruses.

Product Performance Testing
Clinical performance of the subject device mixed with BMA and local bone was evaluated by a comparison of radiographic outcomes (i.e., Lenke fusion score), SF-36 subjective questionnaire, Oswestry disability questionnaire, Visual Analog Scale for back and leg pain, and adverse event profile compared to autograft iliac crest bone. This study demonstrated equivalency between the subject device and predicate autologous iliac crest bone where lumbosacral fusion is indicated.

Dear Mr. Young:
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. 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.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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.
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); good manufacturing practice requirements as set
