#### Device Description

BL Navigated Biopsy Needle contains a calibrated biopsy cannula that is used with a compatible image guided surgery navigation system in stereotactic biopsy of cranial tissue. The device is compatible with specified BrainLab navigation systems (see intended use section below). Like the predicate device, the BL Navigated Biopsy Needle is a pre-sterilized, single-use, stainless steel device and uses a side-cutting cannula where the cutting action is achieved by rotation of an inner cannula within an outer cannula.

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

BL Navigated Biopsy Needle's components include a navigable biopsy cannula, a biopsy cannula stop with screw, a stop adjustment tool and an aspiration tube.

## Indications for Use

The BL Navigated Biopsy Needle is indicated for stereotactic biopsy of cranial tissue using BrainLab AG's VectorVision navigation system. The Navigated Biopsy Needle is a pre-sterilized, single-use, side-cutting needle where the cutting action is achieved by rotation of an inner cannula within an outer cannula.

## Patient Population

The device is intended for use in patients undergoing stereotactic cranial tissue biopsy procedures.

## Environment of Use

The device is intended for use by a trained healthcare professional in a healthcare facility.

## Summary of Technological Characteristics

The BL Navigated Biopsy Needle contains a navigable biopsy cannula constructed with an inner and outer stainless steel needle with a side-cutting window, a plastic hub and a set of retro-reflective discs. The reflective discs allow the device to be registered with BrainLab navigation systems and to be visible during a biopsy procedure. The Set also contains a biopsy cannula stop with screw, a stop adjustment tool and an aspiration tube.

The BL Navigated Biopsy Needle and the predicated devices, the BrainLab Biopsy Needle Type A (K012564) and Medtronic Biopsy Needle (K971247), are based on the following same technological elements: material, construction, registration and tracking method and cutting actions. The table below summarizes the comparison of technological characteristics among the subject device and predicate devices.

| Technical Characteristics | Subject Device (K140705) | BrainLab Biopsy Needle Type A | Medtronic Biopsy Needle |
|----------------------------|--------------------------|-------------------------------|-------------------------|
| Needle Material | Stainless steel | Stainless steel | Stainless steel |
| Biopsy Needle Construction | Inner and outer cannula | Inner and outer cannula | Inner and outer cannula |
| Biopsy Cutting Action | Side cutting | Side cutting | Side cutting |

| | window | window | window |
|-------------------------------------|------------------------------|------------------------------|------------------------------|
| Registration and Tracking<br>method | retro-reflective<br>material | retro-reflective<br>material | retro-reflective<br>material |
| Needle Dimension (diameter) | 2.1 mm | 1.8 mm | 2.1 mm |

There are minor differences in needle dimension between the devices.

#### Summary of Performance Testing

Bench testing was conducted to demonstrate that the BL Navigated Biopsy Needle performs as intended and is substantially equivalent to the predicate device. Tissue extraction testing was conducted to verify the ability of the device to sample tissue. Navigation testing was conducted to verify the compatibility and accuracy of the device with the specified navigation systems. Real-time shelf life testing was conducted to verify that there was no change in visual attributes, dimensional characteristics, or tensile strength after 5 years real time storage. These studies verify that the device is as safe, as effective, and performs as well as or better than the legally marketed predicate device identified above.

The biocompatibility evaluation for the BL Navigated Biopsy Needle was conducted in accordance with ISO 10993-5 Biological evaluation of medical devices -- Part 5: Tests for In Vitro Cytotoxicity and ANSI/AAMI ST72:2011 Bacterial endotoxins - Test methods, routine monitoring, and alternatives to batch testing. The battery of testing included the following tests:

- Cytotoxicity ●
- Pyrogen Testing

The patient contacting components of the Navigated Biopsy Needle are the outer and inner cannula. Patient contact time of the device is less than 24 hours. The outer and inner cannula are both made from AISI 304 stainless steel.

#### Summary

In summary, the non-clinical data support the safety of the device and the hardware verification and validation testing demonstrate that the IZI Navigated Biopsy Needle, used with BrainLab Vector Vision navigation system, should perform as intended in the specified use conditions.
