The 510(k) summary describes a bone putty material and its physical and biological properties. There is no mention of AI, ML, image processing, or any software-based functionality that would typically incorporate these technologies. The performance studies focus on material properties and in-vivo bone repair efficacy.
Yes
The device is indicated for use in the repair of neurosurgical burr holes and contiguous cranial defects, which directly addresses a medical condition or ailment, classifying it as therapeutic.
No
The device is a bone putty used for the repair of cranial defects, which is a therapeutic function, not a diagnostic one.
No
The device description clearly states it is a "sterile, biocompatible, resorbable material" comprising two physical components that are mixed together to form a putty. This is a physical material, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for the repair of neurosurgical burr holes and cranial defects. This is a surgical procedure performed directly on the patient's body.
- Device Description: The device is a bone putty, a material used to fill and repair bone defects. It is applied directly to the surgical site.
- Lack of IVD Characteristics: An IVD is a medical device used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health. This device does not perform any such tests on biological samples.
The device is a surgical implant/material used for bone repair, not a diagnostic tool.

Device Description
MONTAGE-QS Settable, Resorbable Bone Putty is a sterile, biocompatible, resorbable material for use in repair of cranial defects. The MONTAGE-QS device comprises two separate components of putty consistency containing granular calcium phosphate, calcium stearate, vitamin E acetate, a triglyceride, polyalcohols and a mixture of a lactide-diester and polyesterbased polymers. When mixed together, the components of the MONTAGE-QS device form a putty-like material. The resulting hardened, resorbable material is primarily calcium phosphate. MONTAGE-QS components must be mixed immediately prior to use.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Efficacy Evaluation: The cranioplasty efficacy performance of MONTAGE-QS was compared to HydroSet in a rabbit cranial critical-sized defect model. Test results confirmed that each device filled bone defects. From the histology-based assessments, MONTAGE-QS performance for cranioplasty was judged to be equivalent to HydroSet in this critical-sized defect model.
Performance Data: Performance testing included a series of laboratory evaluations and in vivo testing. These evaluations included:
- Bench Testing: Visual Inspection, Putty Stiffness, Putty Vitamin E Acetate Concentration, Hand Mixing Time, Hand Mixing Stickiness, Mixability, Package Leak Test, Temperature Sensitivity, Water Uptake, Swelling and Dissolution.
- In-Vivo Testing: In-vivo animal testing was used to demonstrate substantial equivalence of MONTAGE-QS Settable, Resorbable Bone Putty in the repair of a critical sized cranial bone defect in an animal model compared to the predicate device. Substantial equivalence was assessed from histopathologic evaluation.
- Biocompatibility Testing: Testing was conducted to evaluate the device's biocompatibility in accordance with the recommendations of ISO 10993. The biocompatibility studies included: cytotoxicity, irritation, systemic toxicity, genotoxicity, local tissue toxicity, hemolysis, pyrogenicity and neurotoxicity.
- Clinical Testing: No clinical studies have been conducted in support of this 510(k).

Dear Howard Schrayer:
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 (the 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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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.
