The document describes a synthetic bone void filler material and its physical and chemical properties, along with pre-clinical testing. There is no mention of AI or ML in the intended use, device description, or performance studies. The input imaging modalities mentioned (radiography, micro-CT) are used for evaluating the material's performance, not as input for an AI/ML algorithm within the device itself.
Yes
The device is a bone void filler intended to facilitate the healing process by being resorbed and replaced with host bone, which directly treats or alleviates a condition (bone defects).
No
The device is described as a bone void filler intended to facilitate bone healing, not to diagnose a condition.
No
The device description clearly states it is a synthetic, resorbable bone void filler made of physical materials (beta-tricalcium phosphate, siloxane-containing vaterite, and poly(L-lactide)) in a glass wool-like physical form. This is a physical medical device, not a software-only device.
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 REBOSSIS is a bone void filler intended for use in bony voids or gaps. It is a material that is physically placed into the body to aid in bone healing.
- Device Description: The description details the composition and physical form of the material itself, not a test or assay performed on biological samples.
- Lack of Diagnostic Function: There is no mention of the device being used to diagnose a condition, measure a substance in a biological sample, or provide information about a patient's health status based on in vitro testing.
- Performance Studies: The performance studies focus on the material's properties, biocompatibility, and performance in an animal model for bone regeneration, not on the accuracy or reliability of a diagnostic test.
IVD devices are designed to be used in vitro (outside the body) to examine specimens derived from the human body (such as blood, urine, or tissue) to provide information for diagnostic, monitoring, or compatibility purposes. REBOSSIS is an implantable medical device used in vivo (inside the body) to facilitate bone healing.
N/A
Intended Use / Indications for Use
REBOSSIS is a bone void filler intended for use in bony voids or gaps that are not intrinsic to the stability of the bony structure. These defects may be surgically created osseous defects or osseous defects created from traumatic injury to the bone. REBOSSIS is indicated to be packed gently into bony voids or gaps of the skeletal system (extremities and pelvis), and may be used without hydration or hydrated with bone marrow aspirate or blood. The device provides a bone void filler that is resorbed and replaced with host bone during the healing process.

Device Description
REBOSSIS is a synthetic, resorbable bone void filler. It is composite material consisting of (by weight) 40% beta-tricalcium phosphate (B-TCP), 30% siloxane-containing vaterite (a form of calcium carbonate, CaCO3), and 30% poly(L-lactide). The electrospinning process used in manufacturing REBOSSIS results in a glass wool-like physical form. Due to its physical form, REBOSSIS is flexible and can easily fill defects in appropriate amounts.

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. Biocompatibility testing was performed using methods described in ISO 10993-1, ISO 10993-3, ISO 10993-5, ISO 10993-6, ISO 10993-10, ISO 10993-11, USP 36 and USP 36 .
Material characterization performed included: true density by pycnometry, chemical composition by energy dispersive x-ray spectrometry (EDX), trace elemental analysis by inductively coupled plasma/mass spectroscopy (ICP/MS), residual solvents by the methods described in USP , surface microstructure by scanning electron microscopy (SEM), and polymer properties by gel permeation chromatography (GPC) and differential scanning calorimetry (DSC). The in vitro release kinetics of Si, Ca and P ions were measured using inductively coupled plasma spectroscopy (ICP) at multiple time points after up to 14 days in simulated body fluid. SEM, EDX, and Fourier transform infrared spectroscopy (FTIR) also were performed at time 0 and after 14 days in simulated body fluid.
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 distal femoral condyle critical-sized defect model. Each material was evaluated with three (3) hydration conditions: no hydration (dry, material alone), hydrated with autologous blood, and hydrated with autologous bone marrow aspirate. Hydration with blood or bone marrow aspirate was 1:1 by volume.
The study time points included baseline (time 0), 6 weeks, and 12 weeks. The baseline (time 0) animals included REBOSSIS (dry) and Actifuse Shape (dry) to provide information on the initial amount of material implanted to fill the defects. Autograft bone filled defects (positive control) and empty unfilled defects (negative control) also were evaluated at 6 weeks and 12 weeks. Evaluation endpoints included high-resolution radiography, micro-computed tomography (micro-CT) imaging, undecalcified histologic evaluation, and histomorphometric analysis.
No clinical data were included in this submission.
