Intended Use

The Bio2 CLM-BG Bioactive Scaffold is intended for use as a bone void filler for bony voids or gaps that are not intrinsic to the stability of the bony structure. Bio2 CL.M+BG Bioacive Scaffold is indicated to be gently packed into bony voids or gaps of the skeletal system (i.e. extremitics and pelvis). These defects may be surgically created osseous defects or osseous defects created from traumatic injury to the bone. The product provides a bone void filler that resorbs and is replaced with bone during the healing process.

Device Story

Bio2 CLM-BG Bioactive Scaffold is a synthetic, non-collagenous, osteoconductive bone void filler composed of fiber-based bioactive glass. Available as cylinders, blocks, and wedges, the device is packed into non-structural bony voids or gaps in the extremities and pelvis. Upon implantation, the bioactive glass surface undergoes kinetic modification, forming a calcium phosphate layer similar to bone hydroxyapatite; this layer acts as a scaffold for new bone tissue infiltration. The fibers are slowly resorbed and replaced by host bone during the healing process. The device is provided sterile for single-use by surgeons in clinical settings. The radiopaque nature of the material allows for post-operative monitoring via X-ray. The device benefits patients by facilitating the repair of osseous defects through a resorbable, bioactive scaffolding mechanism.

Clinical Evidence

No human clinical data provided. Evidence consists of bench testing and animal studies. In vitro testing (ISO 23317:2012) confirmed formation of a hydroxyapatite layer in simulated body fluid. In vivo testing in a rabbit critical size defect model evaluated bone formation at 8 and 16 weeks using X-ray, histology, histomorphometry, SEM, and EDX. Results demonstrated the device is as safe and effective as the control material.

Technological Characteristics

Material: Fiber-based bioactive glass; synthetic and non-collagenous. Complies with ASTM F-1538. Form factor: Cylinders, blocks, and wedges. Principle: Osteoconductive, bioactive, resorbable scaffold. Radiopaque. Sterilization: Provided sterile for single use. Connectivity: None.

Indications for Use

Indicated for patients with bony voids or gaps in the skeletal system (extremities and pelvis) that are not intrinsic to the stability of the bony structure, including surgically created osseous defects or those resulting from traumatic injury.

IV. Device Description

The Bio2 Technologies implants are bone void fillers in the shape of cylinders, blocks and wedges. The devices are osteoconductive, bioactive, bone void fillers. The implants are made from a fiber based bioactive glass. The device structure allows tissue infiltration between the bioactive glass fibers. The fibers then are slowly absorbed and replaced by new bone tissue during the healing process. The cylinders, blocks and wedges are provided sterile and are intended for single use.

V. Indications for Use

The Bio2 CLM+BG Bioactive Scaffold is intended for use as a bone void filler for bony voids or gaps that are not intrinsic to the stability of the bony structure. Bio2 CLM-BG Bioactive Scaffold is indicated to be gently packed into bony voids or gaps of the skeletal system (i.e.

extremities and pelvis). These defects may be surgically created osseous defects or osseous defects created from traumatic injury to the bone.

The product provides a bone void filler that resorbs and is replaced with bone during the healing process.

#### VI. Comparison of technological characteristics with the predicate device

Bio2 CLM-BG Bioactive Scaffold like the predicate devices is an osteoconductive, bioactive bone graft device. The Bio2 CLM.BG Bioactive Scaffold complies with the requirements of ASTM F-1538. Similar to the predicate devices In vitro testing confirms the formation of a hydroxyapatite layer on the surface of the implant when immersed in simulated body fluid. In vivo tests have demonstrated bone formation at each post-implantation time point. In the study critical size defects were filled with Bio2 CLM+BG Bioactive Scaffold and the control material. Similar to the predicate device the rabbit femurs were evaluated at 8 and 16 weeks using x-ray, histology, histomorphometry, SEM and EDX. The Bio2 CLM+BG Bioactive Scaffold was shown to be as safe and effective as the control material.

Like the predicate devices Bio2 CLM+BG Bioactive Scaffold consists of different size cylinders, blocks and wedges made of degradable and resorbable bioactive glass. When implanted, a kinetic modification of the surface occurs, resulting in the formation of a calcium phosphate layer that is essentially similar in composition and structure to the hydroxyapatite found in bone mineral. This apatite layer provides scaffolding onto which the patient's new bone will grow allowing repair of the defect. The material is radiopaque. Bio2 CLM+BG Bioactive Scaffold implants are intended for single use and are provided sterile to the user. They are completely synthetic and non-collagenous.

#### VII. Performance Data

Biocompatibility of the device has been established according to blue book memorandum #G95-1 entitled "Use of International Standard ISO-10993, "Biological Evaluation of Medical Devices Part-1: Evaluation and Testing," In vitro bioactivity testing (ISO 23317:2012) shows the material forms a surface apatite layer when submerged in simulated body fluid.

In vivo animal studies show the device achieves bony healing in a critical defect model, confirmed with radiographs, histology and histomorphometry.

#### Conclusions VIII.

The Bio2 CLM+BG Bioactive Scaffold when compared to the predicate have the same intended use and similar indications, technological characteristics, and principals of operation as its predicate devices. In vivo test data demonstrates that the Bio2 CLM-BG Bioactive Scaffold is as safe and effective as the predicate devices. Thus the Bio2 CLM•BG Bioactive Scaffold is substantially equivalent to the predicates.
