Intended Use

MatrixNEURO Preformed Mesh is intended for use in fixation of the cranial bones in procedures such as reconstruction, fracture repair, craniotomies, and osteotomies.

Device Story

MatrixNEURO Preformed Mesh is a titanium cranial implant used for bone fixation. It is precontoured to cover common cranial defects, though surgeons may further contour it intraoperatively to fit specific patient anatomy. The device is manufactured from grade 2 titanium and features an hourglass mesh pattern, single-sided screw recesses, and a strength-based color-coding gradient. It is designed for use with MatrixNEURO Cranial Plating System screws. The device is provided sterile-packed for single use. It is used by surgeons in clinical settings (e.g., OR) to stabilize cranial bones following procedures like craniotomies or fracture repairs. By providing a pre-shaped, compatible fixation solution, the device facilitates efficient surgical reconstruction and bone stabilization, potentially improving procedural outcomes.

Clinical Evidence

No clinical data. Substantial equivalence was determined based on non-clinical bench testing comparing mechanical performance (load at 2 mm displacement, max load, and stiffness) between the subject device and the predicate.

Technological Characteristics

Material: Grade 2 titanium. Form factor: Precontoured mesh with hourglass pattern. Features: Single-sided screw recesses, strength-based color-coding gradient. Compatibility: Designed for use with MatrixNEURO Cranial Plating System screws. Sterilization: Provided sterile-packed. Energy source: None (mechanical implant).

Indications for Use

Indicated for patients requiring cranial bone fixation during reconstruction, fracture repair, craniotomies, and osteotomies.

Regulatory Classification

Identification

A preformed alterable cranioplasty plate is a device that is implanted into a patient to repair a skull defect. It is constructed of a material, e.g., tantalum, that can be altered or reshaped at the time of surgery without changing the chemical behavior of the material.

### Predicate Devices

Synthes MatrixNEURO Cranial Plating System (K123723)

## Indications for Use

MatrixNEURO Preformed Mesh is intended for use in fixation of the cranial bones in procedures such as reconstruction, fracture repair, craniotomies, and osteotomies.

## Device Description

The MatrixNEURO Cranial Plating System consists of bone fixation implants offered in a variety of shapes and sizes to meet the anatomical needs of the patient.

The proposed MatrixNEURO Preformed Meshes are precontoured to cover common cranial defects manufactured from grade 2 titanium that are designed for use with MatrixNEURO Cranial Plating System screws. The Preformed Meshes are offered sterile packed and are intended for single use only.

#### 5 510(k) Summary (continued)

#### Comparison to Predicate Devices

#### Indications

The indications for proposed preformed meshes are identical to the predicate device.

Technological similarities between the predicate MatrixNEURO Reconstruction Mesh and the proposed MatrixNEURO Preformed Mesh:

- Same principles of operation metallic implants for the fixation of bone. .
- . Same thickness as the predicate.
- . Same mesh pattern (hourglass) as the predicate.
- Same bar width as the predicate.
- Same screw recess type (single-sided) as the predicate .
- Same screw recess inner and outer diameter as the predicate and therefore compatible with . same screws.
- . Same strength-based color coding gradient as the predicate.
- . Same material as the predicate.
- Both the proposed device and the predicate are provided sterile-packed. .

Technological differences between the predicate MatrixNEURO Reconstruction Mesh and the proposed MatrixNEURO Preformed Mesh:

- The proposed devices are precontoured to cover common cranial defects and may be further . contoured by the surgeon as necessary to fit the needs of each patient. The predicate device is
- provided flat and may be contoured by the surgeon as necessary to fit the needs of each of ﺘ patient.

#### Non-clinical performance data

Non-clinical testing and analyses comparing the proposed devices to the predicate include:

- Load at 2 mm of displacement .
- . Max Load.between 0 and 2 mm displacement
- . Stiffness at 2 mm of displacement

The non-clinical performance data demonstrate that the mechanical performance of the proposed Synthes MatrixNEURO Preformed Mesh is comparable to that of the predicate.

## Clinical performance data

Clinical testing was not necessary for the determination of substantial equivalence.

### Substantial Equivalence

The proposed devices have the same intended use as the predicate devices. The non-clinical performance data discussed in this submission demonstrate that the proposed devices are as safe, as effective, and perform as well as or better than the predicate devices. It is concluded that the information included in this submission supports substantial equivalence.
