• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 888.3045
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

NanoFUSE® 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 (i.e. the posterolateral spine and pelvis). These defects may be surgically created osseous defects or osseous defects created from traumatic injury to the bone. NanoFUSE® must be used with autograft as a bone graft extender in the posterolateral spine and pelvis. The product provides a bone graft substitute that remodels into the recipient's skeletal system.

Device Story

NanoFUSE is a malleable, putty-like bone void filler consisting of 45S5 bioactive glass particles coated with porcine gelatin. Supplied dry in a sterile syringe; reconstituted at point of use by surgeon with sterile saline, water for injection, or autologous whole blood. Rehydrated material forms a uniform paste/putty; mixed with autograft; extruded into bony voids. Used in clinical settings (e.g., OR) by surgeons. Acts as an osteoconductive scaffold; progressively resorbed and replaced by host bone during remodeling. Benefits patient by providing a bone graft substitute to fill non-structural skeletal gaps.

Clinical Evidence

No human clinical data. Evidence based on in vivo rabbit model studies (24 and 52 weeks) evaluating performance in the posterolateral spine. Results demonstrate substantial equivalence to the primary predicate (NanoFUSE DBM, K142104) in terms of bone remodeling and biocompatibility.

Technological Characteristics

Synthetic 45S5 bioactive glass particles coated with porcine skin-derived gelatin. Provided dry in sterile polymer syringe; reconstituted to malleable paste. Osteoconductive scaffold. Non-pyrogenic. Single-use. No electronic components or software.

Indications for Use

Indicated for patients requiring bone graft extension in surgically created or traumatic osseous defects of the posterolateral spine and pelvis. Must be used with autograft. Not for use in defects intrinsic to skeletal stability.

#### Description:

NanoFUSE® is a malleable, putty-like, bone-void filler. The product is comprised of a 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, medical grade polymer syringe, double-wrapped in peel-back pouches, in a dust cover paperboard carton. An empty sterile syringe for addition of the hydration fluid of choice is also included in the sterile barrier packaging. NanoFUSE® is intended for single patient use only and is non-pyrogenic. Instructions for use are provided by way of a package insert in the paperboard carton.

At point of use, the surgeon reconstitutes the product with an appropriate sterile solution of choice (sterile saline, water for injection, or autologous whole blood). 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 mixed with autograft and gently extruded by the surgeon into the bone void. NanoFUSE® is progressively resorbed and replaced by host bone during the osteo-remodeling process.

#### Indications for Use:

NanoFUSE® 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 (i.e. the posterolateral spine and pelvis). These defects may be surgically created osseous defects or osseous defects created from traumatic injury to the bone. NanoFUSE® must be used with autograft as a bone graft extender in the posterolateral spine and pelvis. The product provides a bone graft substitute that remodels into the recipient's skeletal system.

#### Technological Characteristics:

NanoFUSE® is comprised of synthetic calcium phosphor-silicate material particles (45S5 bioactive glass) 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.

The bioactive glass and gelatin binder in NanoFUSE® is identical to that utilized for the legally marketed primary predicate device (K142104, NanoFUSE® DBM). However, NanoFUSE® DBM incorporates demineralized bone matrix (DBM) whereas the NanoFUSE 510(k) subject device does not.

Both NanoFUSE® and NanoFUSE DBM contain 45S5 bioactive glass and an inert carrier. NanoFUSE DBM is designated as the primary predicate device and was used as a comparative control for in vivo studies in the rabbit.

NanoFUSE® is reconstituted by the addition of fluid of choice (sterile saline, water for injection or autologous whole blood). 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.

#### Safetv and Effectiveness:

The device is provided sterile, for single use only and has a one-vear shelf life, Biocompatibility data from the NanoFUSE® DBM primary predicate device (K142104) was adopted for the NanoFUSE® 510(k) subject device as the NanoFUSE® DBM includes the same 45S5 bioactive glass and porcine gelatin. Also, the packaging for NanoFUSE® DBM is the same as the proposed NanoFUSE device. The use of NanoFUSE® in the posterolateral spine was evaluated in vivo in the rabbit model. Two studies (24 weeks and 52 weeks) demonstrate the device performance is substantially equivalent to the comparative control, NanoFUSE DBM (K142104). These studies further support the biocompatibility of the NanoFUSE® device.

#### Substantial Equivalence:

The bioglass and porcine gelatin in NanoFUSE® are identical to those utilized for the primary predicate device, NanoFUSE® DBM (K142104). NanoFUSE® and NanoFUSE® DBM (K142104) have the same packaging and both devices are labeled as nonpyrogenic. NanoFUSE® is not indicated for use in the extremities as are the predicate devices; therefore, the indications for use relative to NanoFUSE® DBM (K142104) were modified accordingly.

NanoFUSE® is similar in formulation to NovaBone Putty (K110368) as both include 45S5 bioactive glass and an inert carrier to facilitate handling; neither device contains DBM. The proposed NanoFUSE device, NanoFUSE® DBM predicate (142104) and NovaBone Putty predicate (K110368) are all provided sterile, for single use only and are intended for use in the posterolateral spine and pelvis.

NanoFUSE DBM (K142104) was chosen as the comparative control for posterolateral spine studies in the rabbit because the formulation contains the same bioglass and gelatin constituents. Both the 24-week study and 52-week rabbit spine study results demonstrate NanoFUSE® in vivo performance to be substantially equivalent to NanoFUSE DBM (K142104), in consideration that the predicate device includes DBM, which provides an osteoinductive advantage.

Based on the composite of descriptive information and supporting animal data, NanoFUSE® is deemed substantially equivalent to NanoFUSE DBM (K142104), the primary predicate device, when used as a bone graft extender, in accordance with the indications for use and instructional information provided in the device labeling.
