Intended Use

NanoFUSE® DBM is indicated to be gently placed into bony voids or gaps of the skeletal system that are not intrinsic to the stability of the bony structure. It is indicated to be placed into bony voids or gaps of the skeletal structure (e.g., the extremities and pelvis). These defects may be surgically created osseous defects or osseous defects created by traumatic injury to the bone. The product provides a bone graft substitute that remodels into the recipient's skeletal system.

Device Story

NanoFUSE® DBM is a malleable, putty-like bone void filler; composed of human demineralized bone matrix (DBM) and synthetic 45s5 bioactive glass particles, both coated with porcine-derived gelatin. Packaged dry in polypropylene syringes; reconstituted at point of use by surgeon with sterile saline or water. Rehydration occurs in <30 seconds; material extruded into bony defects. Device acts as a scaffold; progressively resorbed and replaced by host bone during osteo-remodeling. Used in clinical settings by surgeons to fill non-structural osseous defects. Osteoinductivity of DBM component verified via in vitro bioassay or in vivo athymic rat model.

Clinical Evidence

No clinical data provided. Evidence relies on bench testing, biocompatibility testing, and pre-clinical animal testing previously conducted for the predicate device. Osteoinductivity is verified via in vitro bioassay or in vivo athymic rat model.

Technological Characteristics

Materials: Human demineralized bone matrix (DBM), 45s5 bioactive glass, porcine-derived gelatin. Form: Dry powder in polypropylene syringe, reconstituted to putty. Sterilization: Radiation. Connectivity: None. Software: None.

Indications for Use

Indicated for patients with bony voids or gaps in the skeletal system (e.g., extremities, pelvis) not intrinsic to structural stability. Defects may be surgically created or traumatic in origin. No specific age or gender contraindications provided.

Regulatory Classification

Identification

A resorbable calcium salt bone void filler device is a resorbable implant intended to fill bony voids or gaps of the extremities, spine, and pelvis that are caused by trauma or surgery and are not intrinsic to the stability of the bony structure.

Special Controls

*Classification.* Class II (special controls). The special control for this device is the FDA guidance document entitled “Class II Special Controls Guidance: Resorbable Calcium Salt Bone Void Filler Device; Guidance for Industry and FDA.” See § 888.1(e) of this chapter for the availability of this guidance.

Description:

NanoFUSE® DBM is a malleable, putty-like, bone-void filler. The product is comprised of human demineralized bone matrix (DBM) and synthetic calcium phosphor-silicate particulate material particles (45s5 bioactive glass), both coated with gelatin derived from porcine skin. These coated particles are packaged dry in a single use, polypropylene syringe (20 cc or 3 cc), double-wrapped in peel-back pouches, and final packaged in a dust cover paperboard carton. The 20 cc syringe will be filled with either of two different fill quantities of dry powder, identified as 10 cc or 5 cc final product volume. The 3 cc syringe will be filled with dry powder, identified as 2 cc final product volume. NanoFUSE® DBM is intended for single patient use only.

At point of use, the surgeon will reconstitute the product with an appropriate sterile solution of his/her choice (sterile saline, water for injection). The coated particles rehydrate in less than 30 seconds and do not require mixing to form a uniform paste or putty. The material is then gently extruded by the surgeon into the appropriate bone voids. NanoFUSE® DBM is progressively resorbed and replaced by host bone during the osteo-remodeling process.

Indications for Use:

NanoFUSE® DBM is indicated to be gently placed into bony voids or gaps of the skeletal system that are not intrinsic to the stability of the bony structure. It is indicated to be placed into bony voids or gaps of

the skeletal structure (e.g., the extremities and pelvis). These defects may be surgically created osseous defects or osseous defects created by traumatic injury to the bone. The product provides a bone graft substitute that remodels into the recipient's skeletal svstem.

#### Technological Characteristics:

The applicant version of NanoFUSE® DBM is identical to the currently legally marketed medical device NanoFUSE® DBM, also manufactured by Nanotherapeutics, Inc. with respect to materials. design, and intended use. The applicant version is comprised of human demineralized bone matrix (DBM) and synthetic calcium phosphor-silicate particulate material particles (45s5 bioactive glass), both coated with gelatin derived from porcine skin. It is provided dry and is reconstituted at the point of use into a paste-like, malleable form that can be molded or manipulated into bony defects.

NanoFUSE® DBM is reconstituted by the addition of fluid and waiting 30 seconds before expelling the contents from the syringe. At 30 seconds, the product extrudes as a very fluid paste and, with time, the gelatin carrier absorbs the fluid, becomes progressively thicker, and eventually sets in a rubbery mass.

Currently, each lot of DBM used in manufacturing the predicate Origen DBM® with Bioactive Glass (NanoFUSE® DBM) is screened for osteoinductivity in an in vitro bioassay. Each lot of DBM used in manufacturing the applicant version of NanoFUSE® DBM will be screened for osteoinductivity with either the in vitro bioassay originally submitted or the in vivo athymic rat model herein submitted.

The scientific technology of NanoFUSE® DBM applicant product. using in vivo testing for osteoinductivity, is identical to the technology used in the FDA cleared predicates. (K062459, K110976)

#### Osteoinductivity Potential:

athymic rat model. Results from this bioassay were correlated to the athymic rat model. Testing each lot of DBM with this cell bioassay or athymic rat model assures that only DBM with osteoinductive potential is used in NanoFUSE® DBM. The combination of DBM. bioactive glass, and porcine gelatin has not been evaluated for osteoinductivity; therefore, it is unknown to what extent the formulation components may alter the osteoinductive character of the DBM. It is unknown how the OI of the DBM component, measured via the in vitro bioassay or athymic rat model, will correlate with human clinical performance of NanoFUSE® DBM.

The change in osteoinductivity potential testing for the DBM does not

alter the fundamental scientific technology of the device and it does not have an effect on the viral clearance and inactivation of the device. A panel of model potential human viruses representing various virus types, sizes, shapes and genomes has previously been evaluated. The viral inactivation testing demonstrated that suitable viral inactivation potential was obtained by the processing method for

a wide spectrum of potential human viruses.

according to ISO 10993.

(NanoFUSE® DBM).

Each lot of DBM incorporated into NanoFUSE® DBM is evaluated for osteoinductive (OI) potential using an in vitro bioassay or in vivo

Viral Clearance and Inactivation:

Safety and Effectiveness:

The change in osteoinductivity potential testing for the DBM does not alter the fundamental scientific technology of the device and it does not have an effect on the biocompatibility of the device. Biocompatibility testing, pre-clinical animal testing and in vitro bench testing has previously been conducted to evaluate the biological safety and performance characteristics of NanoFUSE® DBM

The change in osteoinductivity potential testing for the DBM does not alter the fundamental scientific technology of the device. Based on the testing provided, the submitted change does not have an effect on the safety or effectiveness of the device. Therefore, the applicant version of NanoFUSE® DBM is substantially equivalent to the currently cleared version of Origen DBM® with Bioactive Glass
