### 8. Non-Clinical

Biocompatibility:

The materials of construction for the Stryker iVAS ® Bone Biopsy Kit have not changed since the device was originally cleared via K032943 (10G, 11G) and K141673 (8G). Therefore, biocompatibility testing is not required.

#### Bench:

The following bench testing was conducted on the subject Stryker iVAS® Bone Biopsy Kit. The testing was conducted in a manner as similar as possible to how the biopsy device will be used by the healthcare professional.

Axial Torque and Non-axial Torque (11G) was performed to verify torsional performance of the subject device. All samples surpassed all acceptance criteria.

Compressive force testing was completed on the obturator (10G) to simulate compression during clinical use. All samples surpassed all acceptance criteria.

Axial Tensile Force (10G) was performed to verify the functional performance of the subject device at T=0. All samples surpassed all acceptance criteria.

Compressive Force and Axial Tensile Force was performed on the obturator (11G) to verify functional and compressive performance. All samples surpassed all acceptance criteria.

{7}------------------------------------------------

Impact and Axial Compressive testing was to verify the impact and compressive performance of the subject device. All samples surpassed all acceptance criteria.

Impact testing was performed on the subject device to confirm functional specifications. All samples surpassed all acceptance criteria.

The acceptance criteria for the predicate devices is similar to the acceptance criteria for the subject bone biopsy kit, demonstrating equivalence of the subject device to the predicate biopsy devices.

#### 9. Clinical Testing

No clinical testing was deemed necessary for this 510(k).

#### 10. Substantial Equivalence Conclusion

The Stryker iVAS ® Bone Biopsy Kit and predicate devices have the same fundamental scientific technology, principal of operation and mode of action.

The addition of bone to the intended use for the subject device does not raise new questions of safety and effectiveness. A review of recalls, Maude data, clinical literature, and a risk review was completed. There are no new or previously unidentified complications or additional harms associated with the use of biopsy needles when the indication is expanded to include bone.

Although there are a few differences in the technological characteristics of the subject and predicate devices, they are insignificant overall. The technological differences between the subject and predicate devices do not raise new types of safety and effectiveness questions. The performance testing completed proves that the subject device has the same performance characteristics as the predicate device.

Therefore it is proposed that the subject Stryker iVAS® Biopsy Kit is substantially equivalent to the predicate device (Coaxial Bone and Vertebral Body Biopsy Needle (K070091).
