Intended Use

BioSphere MIS Putty is indicated only for bony voids or gaps that are not intrinsic to the stability of the bony structure. BioSphere MIS Putty is indicated to be gently packed into bony voids or gaps of the skeletal system as a bone void filler in the extremities and pelvis, and as a bone graft extender in the posterolateral spine. These defects may be surgically created 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

BioSphere MIS Putty is an osteoconductive, bioactive bone void filler composed of 45S5 bioactive glass particles and an inert, moldable carrier. It is designed for implantation into bony voids or gaps. Upon implantation, the carrier is absorbed, and the spherical bioactive glass particles provide an osteoconductive surface; the natural packing of spheres creates 3D interconnected porosity to facilitate bone regeneration. The device is used by surgeons in clinical settings to fill defects in the extremities, pelvis, or posterolateral spine. The subject device modifies the predicate by supplying the putty in a prefilled cannula with a delivery gun to improve access to deep or minimally invasive surgical sites. The delivery mechanism does not alter the bone regeneration mechanism. The healthcare provider uses the delivery gun to extrude the putty into the target site; the device resorbs and is replaced by bone during healing.

Clinical Evidence

No clinical data. Bench testing only. Performance data included quantitative putty extrusion testing (reproducible amounts across temperatures and cannula conditions), 3-point bending tests for cannula structural integrity, qualitative delivery gun assembly assessment, and biocompatibility testing (non-cytotoxicity and endotoxin levels).

Technological Characteristics

Composition: 45S5 bioactive glass particles and inert moldable carrier. Form factor: Putty supplied in prefilled cannula with delivery gun. Principle: Osteoconductive bone void filler; 3D interconnected porosity via spherical particle packing. Sterilization: Not specified. Connectivity: None.

Indications for Use

Indicated for bony voids or gaps in the skeletal system (extremities and pelvis) not intrinsic to structural stability, and as a bone graft extender in the posterolateral spine. Applicable to surgically created or traumatic osseous defects.

#### 4. Predicate Device:

BioSphere Putty (K140844, K122868)

#### 5. Device Description and Summary of Technological Characteristics:

BioSphere MIS Putty ("BioSphere MIS") is an osteoconductive, bioactive bone void filler that, like its predicate device, is composed primarily of medical-grade 4555 bioactive glass particles. The composition and formula of this material is unchanged and is identical to that used in the BioSphere Putty predicate. The bioactive glass is mixed with an inert, moldable carrier using the exact same composition and formula as used in the predicate device.

The only difference between the two devices is that BioSphere MIS Putty is supplied in a prefilled cannula with a delivery gun to aid with placement into certain types of bony voids that are otherwise difficult to reach. The manner in which the device is delivered to the target site does not play any role in the putty achieving its intended clinical purpose (i.e., supporting bone regeneration).

{4}------------------------------------------------

Upon implantation of BioSphere MIS Putty into the target site, the carrier is absorbed by the site and the remaining bioactive glass particles provide an osteoconductive surface for bone formation. The bioactive glass particles are supplied in a spherical form, and the natural packing of the spheres creates 3-dimensional, interconnected porosity that allows for bone regeneration throughout the defect site. This is the same mechanism of action as with the predicate. In the posterolateral spine, BioSphere MIS Putty can be combined with autograff as a bone graft extender in the same manner as the predicate BioSphere Putty.

# 6. Intended Use / Indications for Use:

BioSphere MIS Putty is indicated only for bony voids or gaps that are not intrinsic to the stability of the bony structure. BioSphere MIS Putty is indicated to be gently packed into bony voids or gaps of the skeletal system as a bone void filler in the extremities and pelvis, and as a bone graft extender in the posterolateral spine. 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.

# 7. Purpose of 510(k):

The purpose of this 510(k) is to modify the BioSphere Putty (K140844) by supplying the final putty formulation pre-filled in a cannula, with a delivery qun, instead of in an open bore syringe. This modification is being made to enhance access of the device to bony voids or gaps that are within the cleared predicate's indications for use, but were previously difficult to reach - namely, deep graft sites and graft sites resulting from minimally invasive surgery.

#### 8. Performance Data:

BioSphere MIS Putty was characterized by a variety of quantitative tests and qualitative assessments.

- . Putty extrusion was evaluated by measuring the dispensed putty amount following each pull of the delivery gun trigger. The results showed that the delivery gun was able to extrude a reproducible amount of putty for each trigger pull.
- o Assessments of putty extrusion were also conducted using room temperature and refrigerated samples to mimic colder operating room temperatures. Additionally, extrusion was evaluated with an open and partially blocked cannula end. The delivery gun was effective in extruding putty from the cannula regardless of putty temperature, and was able to extrude the putty through a partially blocked end.
- . A 3-point bending test was used to demonstrate that the cannulas did not critically fail resulting in fracture pieces or broken edges. All cannulas preferentially failed through plastic deformation, as seen by buckling and bending of the cannula.
- . A qualitative assessment of the delivery gun assembly showed that the cannula was easily attached and a stable attachment was maintained during putty extrusion.
- o Confirmatory testing of the BioSphere MIS Putty components showed the product was non-cytotoxic and had acceptable endotoxin levels.

### 9. Conclusion:

BioSphere MIS Putty is as safe and effective as the predicate device. BioSphere MIS Putty has the same intended uses and similar indications, technological characteristics, and principles of operation as its predicate device. The only difference between the modified device and the cleared predicate (change in delivery mechanism from an open bore syringe to a cannula with delivery gun) does not impact its function as a bone void filler and raise no new issues of safety or effectiveness. Thus, BioSphere MIS Putty is substantially equivalent to the predicate.
