The summary describes a calcium phosphate cement for bone repair and augmentation. There is no mention of AI, ML, image processing, or any other technology typically associated with AI/ML in medical devices. The performance studies focus on material properties like setting time and compressive strength.
No
The device is a bone cement used for repair and augmentation of bony contours, which falls under restorative or reconstructive purposes rather than directly treating a disease or condition.
No
Justification: PolyBone is described as a self-setting calcium phosphate cement intended for repairing cranial defects and augmenting bony contour. Its purpose is to physically restore or augment bone, not to diagnose a condition.
No
The device description clearly states that PolyBone is a physical material (calcium phosphate cement) composed of specific chemical components, intended for surgical use. There is no mention of software as a component or the primary function of the 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 PolyBone is a self-setting calcium phosphate cement for the repair and augmentation of bony defects in the craniofacial skeleton. This is a surgical/implantable device, not a diagnostic test performed on samples taken from the body.
- Device Description: The description details the chemical composition of a bone cement, further supporting its use as a material for surgical repair.
- Lack of IVD Characteristics: There is no mention of analyzing samples (blood, urine, tissue, etc.), detecting biomarkers, or providing diagnostic information about a patient's health status.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. PolyBone's function is to physically repair bone defects.

Intended Use / Indications for Use
PolyBone is a self-setting, calcium phosphate cement intended for use in the repair of neurosurgical burr holes, contiguous craniotomy cuts and other cranial defiect as well as in the augmentation or restoration of bony contour in the craniofacial skeleton.

Summary of Performance Studies
The properties of both devices have the equivalence in the doughing time, setting time, working time and pH. The different points are compressive strength and dissolution rate. The compressive strength force of predicate is 60 MPa and of Polybone is 22.7MPa. The predicate device is used in the cortical bone and Polybone is in cancellous bone. Minimum 2.6 MPa is the acceptance criteria for Type 2 in ISO 7490:2000 Dental gypsum-bonded casting investments. In the dissolution rate Polybone has more rapid rate than the predicate.

§ 882.5300 Methyl methacrylate for cranioplasty.
(a)
Identification. Methyl methacrylate for cranioplasty (skull repair) is a self-curing acrylic that a surgeon uses to repair a skull defect in a patient. At the time of surgery, the surgeon initiates polymerization of the material and forms it into a plate or other appropriate shape to repair the defect.(b)
Classification. Class II (performance standards).

Suite 601 World Meridian Venture Center, 60-24 Gasan-dong, IX Kyungwon Medical Geumcheon-gu, Seoul, Korea 153-801
Both products have the same indication for use.
Chemical Similarities
Both products are made up from Calcium phosphate family.
Performance Properties Similarities
The properties of both devices have the equivalence in the doughing time, setting time, working time and pH. The different points are compressive strength and dissolution rate. The compressive strength force of predicate is 60 MPa and of Polybone is 22.7MPa. The predicate device is used in the cortical bone and Polybone is in cancellous bone. Minimum 2.6 MPa is the acceptance criteria for Type 2 in ISO 7490:2000 Dental gypsum-bonded casting investments. In the dissolution rate Polybone has more rapid rate than the predicate.
Biocompatibility
The biocompatibility of Polybone has been performed by ISO 10993-1:2003; cytotoxicity, sensitization, irritation, intracutaneous reactivity, systemic toxicity, subchronic toxicity, genotoxicity and implantation. The testing results show Polybone to be biologically safe.
Therefore, we believe that Polybone is substantially equivalent to predicated device according to the above information in terms of component, indication for use, chemical and performance priorities.
7. Conclusions :
Based on the information provided in this premarket notification Kyungwon Medical Co., Ltd. concludes that PolyBone is safe and effective and substantially equivalent to predicate devices as described herein.
