Intended Use

The Longeviti ClearFit™ Cranial Implant is designed and manufactured individually for each adult patient to correct bony voids and/or defects of the cranium.

Device Story

Patient-specific, implantable cranioplasty plates; manufactured from polymethyl methacrylate (PMMA). Design derived from patient CT scan data. Used to restore cranial bony voids/defects. Provided sterile; fixated to cranial bone using commercially available fasteners. Optional 2mm diameter perfusion holes available upon surgeon request. Used by neurosurgeons in clinical settings. Benefits patient by providing custom-fit structural reconstruction of the cranium.

Clinical Evidence

Bench testing only. Evaluations included ISO 10993-1, 10993-5 (cytotoxicity), 10993-10 (irritation/sensitization), and 10993-11 (material-mediated pyrogenicity). Mechanical testing included ASTM D7028 (Glass Transition), ASTM D638-14 (tensile strength), ASTM D790-15 (flexural strength), and ASTM D4812-11 (impact strength). Sterility/pyrogenicity verified via AAMI 11737-1 and ANSI ST72:2011/(R)2016. All results were acceptable.

Technological Characteristics

Patient-specific cranioplasty plates made of PMMA. Max surface area 411 cm²; nominal thickness 4mm (max 5mm). Optional 2mm diameter perfusion holes. Mechanical properties verified per ASTM D638-14, D790-15, D4812-11, D7028. Biocompatibility per ISO 10993 series. Provided sterile.

Indications for Use

Indicated for adult patients requiring correction of bony voids and/or defects of the cranium.

Regulatory Classification

Identification

A preformed nonalterable cranioplasty plate is a device that is implanted in a patient to repair a skull defect and is constructed of a material, e.g., stainless steel or vitallium, that cannot be altered or reshaped at the time of surgery without changing the chemical behavior of the material.

Dear Elaine Duncan:

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. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. 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 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 (QS) 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.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

| Substantially<br>Equivalent To: | The Longeviti ClearFit™ Cranial implant is substantially equivalent to the<br>following legally marketed devices:<br>Longeviti PMMA Static Cranial Implant,<br>Longeviti Neuro Solutions K170410 |
| Device Description | The Longeviti ClearFit Implant is patient specific, implantable prosthetic<br>cranioplasty plates intended to correct and/or restore bony voids and/or defects<br>of the cranium. The implant is manufactured from polymethyl methacrylate<br>materials and are designed using the patient's CT scan data. The devices are<br>provided sterile and can be fixated to cranial bone using commercially available<br>fasteners. An identical backup implant may be supplied as a courtesy to the<br>surgeon, according to custom, but is not required. The typical maximum single<br>plate size does not exceed a total surface area of 411 cm² and should have a<br>nominal thickness of 4mm, not to exceed 5mm, to ensure physical integrity.<br>Perfusion holes (also known as drainage holes) are available upon surgeon<br>request at the time of ordering. Perfusion holes are 2mm in diameter and spaced<br>at least 10mm apart. |
| Indication for Use | The Longeviti ClearFit Cranial implant is designed and manufactured<br>individually for each adult patient to correct bony voids and/or defects of the<br>cranium. |
| Comparison of<br>Technological<br>Characteristics | The changes compared to the Longeviti Cranial Implant covered in this<br>submission are: 1) Trade name change and plural to singular description<br>(previously updated via registration), 2) Recognition of option for perfusion<br>holes and 3) description of process changes. There are no technological<br>changes to the biomaterial (PMMA) and no change to the materials of<br>manufacturing There are no changes to packaging or sterilization processes. |
