Intended Use

The PEEK Customized Cranial Implant Kit is indicated for the augmentation of bony and/or soft tissue deformities in the cranial and craniofacial skeleton (orbital rim, zygoma, and adjacent bone); including but not limited to, the correction and prevention of persistent temporal hollowing (PTH) in patients 3.5 years of age and older.

Device Story

Device provides customized patient-specific cranial/craniofacial implants; manufactured from PEEK. Input consists of patient CT/CBCT data and surgeon input. Device fills bony voids, defects, and contour irregularities in non-load bearing regions. Used in clinical settings by surgeons; supports single-stage surgical procedures.

Benefits include restoration of skeletal contour and correction of temporal hollowing.

Clinical Evidence

No clinical data. Substantial equivalence supported by bench testing and end-user validation lab. Validation confirmed successful implant fit and procedure performance for single-stage surgery with/without surgical aids (marking guides, virtual templates, navigation).

Technological Characteristics

Material: PEEK. Principle: Preformed alterable cranioplasty plate for filling bony voids/defects. Form factor: Customized patient-specific implant. Connectivity: None. Sterilization: Identical to predicate. Software: None.

Indications for Use

Indicated for patients 3.5 years and older requiring augmentation or restoration of bony/soft tissue deformities in the cranial and craniofacial skeleton, including orbital rim, zygoma, and adjacent bone, and for correction/prevention of persistent temporal hollowing (PTH).

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.

Dear Zainab Amini:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.

In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's

{1}------------------------------------------------

requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

#### V. INDICATIONS FOR USE

The PEEK Customized Cranial Implant Kit is indicated for the augmentation and/or restoration of bony and/or soft tissue deformities in the cranial and craniofacial skeleton (orbital rim, zygoma. and adjacent bone); including but not limited to, the correction and prevention of persistent temporal hollowing (PTH) in patients 3.5 years of age and older.

#### VI. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE

The PEEK Customized Cranial Implant Kit is compared to its predicate device for substantial equivalence based on the following criteria:

- A. Principle of Operation
- B. Technological Characteristics

# A. Principle of Operation

The basic principle of operation for the PEEK Customized Cranial Implant Kit is to fill bony voids, defects, and contour irregularities in non-load bearing regions of the cranial and craniofacial skeleton.

## B. Technological and Operational Characteristics

Both the Subject and Predicate Devices have similar technological characteristics, and the principle of operation, mode of fixation, and design specification and manufacturing processes are all identical. Additionally, the subject device can be used in a single stage surgical procedure with or without marking guides or a navigation system to transfer the resection outline.

### VII. PERFORMANCE DATA

### Biocompatibility Testing

Biocompatibility and sterility testing of the device is a basis for substantial equivalence. There is no change in the material, duration of contact, or reprocessing methods for the PEEK Customized Cranial Implant Kit. As the design and manufacturing processes, materials, and packaging processes are identical for both the predicate and the subject devices.

### Performance Bench Testing

Both the subject and predicate devices are designed similarly and manufactured identically. The majority of the Performance Bench testing of the predicate device is valid for the subject device. Additionally, an end-user validation lab was conducted to evaluate the subject device and to support the basis for substantial equivalence. Table below provides a summary of the end-user validation.

| Test | Test Methods Summary | Results |
|------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| End-User<br>Validation | • Single Stage surgical procedure<br>with/&without the following surgical<br>aid options:<br>- Marking guides/guided; Virtual<br>template/Navigation system;<br>w/out surgical aid<br>• Implant Fit | All V&V activities that were performed<br>met their respective acceptance criteria.<br>All end-user validation tasks were<br>completed, passed successfully, and<br>supports the substantial equivalence of<br>the subject device to the predicate<br>device. |

### Animal Testing

Animal testing was not required as a basis for substantial equivalence.

### Clinical Testing

Clinical testing was not required as a basis for substantial equivalence.

### VIII. CONCLUSIONS

The evidence presented demonstrates that the subject device is as safe and effective as the legally marketed predicate and does not change nor raise any new questions of safety and effectiveness. In conclusion, in accordance to the requirement of 21 CFR 807.87, the PEEK Customized Cranial Implant Kit is substantially equivalent with respect to the safety and effectiveness to the legally marketed predicate device, K190229.
