Intended Use

PEEK Customized Cranial Implant Kit is intended to be used to replace bony voids in the cranial and the craniofacial skeleton.

Device Story

Device is a patient-specific implant kit for cranial/craniofacial reconstruction. Input: patient CT scan data. Process: surgeon initiates request via 'eRequest Lifecycle' online system; manufacturer uses 'Virtual Implant Design Process' (VIDP) to create 3D model of skull and defect; design proposal generated and reviewed/approved remotely by surgeon. Output: customized PEEK implant and host bone model. Used in clinical settings; operated by surgeons. Implant fixated to native bone using self-tapping screws. Benefits: provides patient-specific anatomical fit for bony voids.

Clinical Evidence

Bench testing only. Performance tests included stability, trimming, drilling, screw insertion, and screw pull-out tests. Results demonstrated mechanical strength comparable to native skull and integrity during surgical manipulation. Handling test performed in a cadaver lab with surgeons confirmed implants met user needs and fit defects.

Technological Characteristics

Material: Medical grade PEEK Optima LT1. Design: Patient-specific 3D geometry derived from CT data via Virtual Implant Design Process (VIDP). Connectivity: Online 'eRequest Lifecycle' system for data exchange and design approval. Delivery: Non-sterile. Fixation: Self-tapping screws.

Indications for Use

Indicated for filling bony voids in the cranial and craniofacial skeleton in patients 12 years of age and older.

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 Patient Specific Cranial/Craniofacial Implant (K053199)
• Stryker Patient Specific Polymer Implant (K111065)

#### Intended Use:

PEEK Customized Cranial Implant Kit is intended to replace bony voids in the cranial and the craniofacial skeleton.

### Indications for Use:

The PEEK Customized Cranial Implant Kit is indicated for filling bony voids in the cranial and craniofacial skeleton in patients 12 years of age and older.

### Device Description:

PEEK Customized Implant Kit consists of the PEEK Customized Cranial Implant or the PEEK Customized Craniofacial Implant, the Host Bone Model, and the Design Proposal.

# PEEK Customized Cranial Implant:

The PEEK Customized Cranial Implant is a customized patient-specific implant based on CT-data and input by the surgeon. The implant is fabricated from polyetheretherketone (PEEK) and is intended to be used to fill bony voids in the cranial skeleton. It is delivered non-sterile.

# PEEK Customized Craniofacial Implant:

The PEEK Customized Craniofacial Implant is a customized patient-specific implant based on CT-data. The implant is fabricated from polyetheretherketone (PEEK) and is intended to be used to fill bony voids in the craniofacial region (orbital rim, zygoma, and adjacent bone). The implant matches the shape and dimensions of the missing bone fragments. It is delivered non-sterile.

The host bone model is provided as a preoperative guide to demonstrate orientation and fit of the Peek Customized Cranial Implant. The Design Proposal is a presentation of virtual 3-dimensional models of the implant design. The PEEK Customized Cranial Implant is offered in different sizes based on the size of the cranial defect. Depending on the surgeon's preference, the PEEK Customized Cranial Implant may be constructed in varying thicknesses, wall designs, number of dura suture holes and dura suture hole diameters. The PEEK Customized Cranial Implant is fixated to the native bone with

{2}------------------------------------------------

#### Traditional 510(k)

Stryker Neuro, Midface or Upperface self-tapping screws. The PEEK Customized Cranial and Craniofacial Implant Kit is bundled with an online ordering system called "eRequest Lifecycle", whereby the user can initiate a case request, upload the patient specific image data, download the Design Proposal and approve the implant design.

#### Technological Characteristics:

The PEEK Customized Cranial and Craniofacial Implant Kit is designed individually on a patient-by- patient basis upon request of the surgeon using a validated "Virtual Implant Design Process" (VIDP). A CT scan received from the health care facility is used to generate a 3 dimensional model of the skull with the defect to be filled. This 3dimensional model of the skull is then used to design the implant. The design is virtually presented as a Design Proposal, which is then reviewed and approved remotely by the surgeon, and modified if desired. Once the design is approved, the PEEK Customized Cranial and Craniofacial Implant Kit and the Host Bone Model are manufactured and shipped to the health care facility along with a print of the approved Design Proposal. The PEEK Customized Cranial and Craniofacial Implant Kit are offered non-sterile to the customer.

The PEEK Customized Cranial and Craniofacial Implant Kit are similar or identical to its predicate devices in the following technical characteristics:

- · Material: The PEEK Customized Cranial Implant and the Synthes Patient Specific Cranial/Craniofacial Implant - K053199 are made of the identical medical grade PEEK Optima LT1 from the same supplier, Invibio
- Design: The PEEK Customized Cranial Implant and the Stryker Patient Specific Polymer Implant - K111065 are designed using the identical software and Virtual Implant Design Process (VIDP)
- The PEEK Customized Cranial Implant and the Synthes Patient · Sterility: · Specific Cranial/Craniofacial Implant – K053199 are delivered non-sterile to the user
- Case initiation and data exchange: The PEEK Customized Cranial Implant and the Stryker Patient Specific Polymer Implant – K111065 use identical systems

{3}------------------------------------------------

for case initiation, uploading of imaging data, downloading of Design Proposal and approval.

# Performance Data:

Various performance tests including stability tests, trimming tests, drilling tests, screw insertion tests and screw pull-out tests were performed on the PEEK Customized Cranial Implants and Craniofacial Implants. The results of these tests demonstrated that the PEEK Customized Cranial and craniofacial Implants have mechanical strength comparable to native skull, and do not melt or lose integrity upon burring, drilling and/or screw insertion with recommended burrs, drills and screws. A handling test performed in a Cadaver Lab with surgeons demonstrated that the implants met the user needs and fit the defects.

#### Substantial Equivalence:

The PEEK Customized Cranial and Craniofacial Implant Kit are substantially equivalent to its predicate devices in regards to intended use, design, materials and operational principle. Further, the performance data confirms that the PEEK Customized Cranial and Craniofacial Implant Kit are safe and effective and performs as well as its predicate devices listed below.
