No
The document describes a bone graft material and its physical properties and performance in animal studies. There is no mention of any software, algorithms, or data processing that would indicate the use of AI or ML.
Yes
The device is an implant intended to fill bony voids or gaps of the skeletal system and is replaced by bone during the healing process, which directly addresses a medical condition or disease by restoring function or health.
No
The device, NovoGro Putty, is described as an implant used to fill bony voids, which is a therapeutic function, not a diagnostic one.
No
The device description clearly states it is a physical implant provided as two components (dry powder and aqueous solution) that are mixed intra-operatively to form a putty. This is a physical medical device, not software.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- Intended Use: The intended use is to fill bony voids or gaps in the skeletal system. This is a therapeutic and structural application within the body.
- Device Description: The device is a material intended for implantation.
- Performance Studies: The performance studies involve animal testing to evaluate bone formation and integration within the skeletal system.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue samples) to provide information for diagnosis, monitoring, or screening.
IVDs are used outside the body to analyze samples and provide diagnostic information. This device is used inside the body for structural support and bone regeneration.
N/A
Intended Use / Indications for Use
NovoGro Putty is an implant intended to fill bony voids or gaps of the skeletal system (i.e. extremities, posterolateral spine and pelvis). NovoGro must be used with autograft as a bone extender in the posterolateral spine. These osseous defects may be surgically created or the result of traumatic injury to the bone and are not intrinsic to the stability of the bony structure. The device resorbs and is replaced with bone during the healing process.

Device Description
NovoGro Putty is provided to the end-user as two components (dry powder and aqueous solution) that must be mixed intra-operatively prior to implantation using the supplied mixing system to form a moldable cohesive putty-like graft. The dry powder component of NovoGro Putty contains spherical particles that are composed primarily of a co-precipitate of dicalcium phosphate anhydrite Imonetite. CaHPO4], magnesium phosphate trihydrate [newberyite, Mg(PO2OH)+3(H2O)] and sodium hydrogen phosphate [NaH2PO4]. Small amounts of silica (SiO2) and magnesium oxide (MgO) are combined with this co-precipitate during manufacturing. These spherical particles are mixed heterogeneously with dry sodium carboxymethyl cellulose (CMC) powder to enhance the handling properties of the final mixed graft. The aqueous component of NovoGro is ultrapure reverse osmosis deionized water (DI H2O). NovoGro Putty is provided sterile for single use in volumes ranging from 1 cc to 20 cc. NovoGro Putty is provided in a kit with a mixing system, a vial of ultrapure water for mixing, and a graduated syringe to measure the correct volume of the supplied ultrapure water to add to the dry component.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Pre-clinical testing data submitted, referenced, or relied upon to demonstrate substantial equivalence included chemical composition, physical properties, biocompatibility, and performance characteristics.
Chemical characterization of the subject device included identification of crystalline and non-crystalline components using powder x-ray diffraction (PXRD) and Fourier transform infrared spectroscopy (FTIR), and elemental composition analysis (including heavy metal content) using ion coupled plasma mass spectrometry (ICP-MS). Calcium dissolution and pH measurement testing were performed, and chemical characterization was performed using methods described in ASTM F2024, ASTM F1185, and ASTM F1926/F1926M.
Physical characterization of the subject device included scanning electron microscopy (SEM); particle size distribution; device mass, volume, and density by gas displacement pycnometry; surface area by gas adsorption; and device porosity by mercury intrusion porosimetry.
Biocompatibility testing was performed using methods described in AAMI/ANSI/ISO 10993-1, ISO 10993-3, AAMI/ANSI/ISO 10993-5, ISO 10993-10, ISO 10993-12, and ISO 10993-12, and ISO 10993-18. Material mediated pyrogenicity testing and bacterial endotoxin testing were performed using the methods described in ISO 10993-11 and AAMI/ANSI ST72, respectively.
Sterilization validation, sterile barrier shelf life, and product shelf life testing were performed according to AAMI/ANSI/ISO 11137-1, AAMI/ANSI/ISO 11137-2. ASTM D4169, ASTM F1980, ASTM F1886/F1886M, ASTM F2096, and ASTM F88/F88M.
Animal testing performed to demonstrate substantial equivalence included determination of radiographic, histologic, and histomorphometric characteristics of the subject device and the predicate device in a rabbit posterolateral spine fusion model. Animals implanted with autograft (positive control) also were evaluated. The study time points included baseline (time 0), 6 weeks, and 12 weeks. Evaluation endpoints included manual palpation, range of motion/flexibility testing, plain and high-resolution radiography, micro-computed tomography (micro-CT) imaging, undecalcified histologic evaluation, and histomorphometric analysis. Histology sections also were graded according to AAMI/ANSI/ISO 10993-6 (Annex E). No clinical data were included in this submission.
Bioactivity testing included an in vitro study comparing the subject device NovoGro Putty, positive control (bioactive glass), and negative control (polyethylene) in the presence of simulated body fluid. Apatitic calcium phosphate formation was observed on surface of the NovoGro Putty and a positive control, but not on the surface of the negative control. Bioactivity has not been evaluated in human clinical trials.
Key results: The results of the study demonstrated that the performance of the subject device was equivalent to that of the predicate device K140375.

6
The subject device and the primary predicate device have intended use, the same product classification and product code (MQV), and have similar Indications for Use statements. The subject device and the primary predicate devices are bone void fillers that are intended for bony voids or gaps that are not intrinsic to the stability of the bony structure. The subject device and primary predicate device are indicated for use in the posterolateral spine with autograft bone (extender). Although the subject device and the primary predicate have slightly different Indications for Use language, this difference in language does not change the intended use as a bone void filler in the posterolateral spine.
The subject device and the primary predicate device each incorporate calcium phosphate materials within a polymeric binder or scaffold. The subject device polymeric binder is sodium carboxymethyl cellulose (CMC), and the primary predicate K140375 scaffold is type I bovine collagen. The subject device and the reference predicate device are identical in material composition and physical form. The subject device and the predicate devices are provided sterile for single-patient, single-use in similar ranges of graft volumes.
The subject device and the reference predicate device K162087 are the same except for the indications for use. The subject device is not to be hydrated after mixing of the dry powder component with the ultrapure water, the primary predicate K140375 is to be hydrated with bone marrow aspirate and/or sterile water prior to use. In the posterolateral spine the subject device must be mixed with autograft bone, whereas the primary predicate device may be used without or with autograft bone.
The radiographic, histologic, and histomorphometric performance of the subject device were compared to that of the primary predicate device K140375 in a rabbit posterolateral fusion model. The results of the study demonstrated that the performance of the subject device was equivalent to that of the predicate device K140375.
CONCLUSION
The subject device and the predicate devices have the same intended use, have similar technological characteristics, and are made of similar materials. The subject device and the predicate devices are provided sterile for single-patient, single-use in similar ranges of graft volumes, and are packaged in similar materials and are sterilized using similar methods. The data included in this submission demonstrate substantial equivalence to the predicate device listed above.
