The ePTFE-Coated Auricular Implant is intended for reconstruction of the external ear.
The ePTFE-Coated Auricular Implant is intended for reconstruction of the external ear. It is intended to be a long term, single use implant. Implantation of the device by the surgeon produces a contour to reconstruct the patient's outer ear feature. A surgically created "pocket" at the implantation site is made by the surgeon for placement of the device (typically placed on the skeletal feature below the soft muscle tissue). The ePTFE-Coated Auricular is composed of a silicone elastomer core with an outer layer of ePTFE (expanded polytetrafluoroethylene) and is shaped approximately to that of the external ear. The implant comes in nine sizes and the surgeon has the option to trim the implant to fit the patient's need. The implant is provided sterile or non-sterile, as either the "Left" or "Right" side.
The provided text is a 510(k) Premarket Notification from the FDA regarding an ePTFE-Coated Auricular Implant. This document is a regulatory approval for a physical medical device (an implant for ear reconstruction), not a software or AI-based medical device.
Therefore, the concepts of "acceptance criteria" and "study proving the device meets acceptance criteria" as they relate to AI/ML performance (e.g., sensitivity, specificity, AUC) are not applicable to this document. The document describes:
- Device Description: A silicone elastomer core with an ePTFE outer layer, shaped for external ear reconstruction.
- Intended Use: Reconstruction of the external ear.
- Predicate Devices: Other ear prostheses and facial implants, primarily based on material and design similarities, and identical indications for use.
- Non-Clinical Testing:
- Biocompatibility testing: In compliance with ISO 10993-1, covering cytotoxicity, irritation, sensitization, acute systemic toxicity, material-mediated pyrogenicity, implantation, and chemical characterization.
- Bond strength testing: To confirm the integrity of the silicone/ePTFE bond despite aging, repetitive sterilization, and pigment.
- Conclusion: The device is substantially equivalent to predicate devices based on identical indications for use and similar technological characteristics, and material testing indicates it does not raise new issues of safety or efficacy.
There is no mention of a "study that proves the device meets the acceptance criteria" in terms of an AI/ML algorithm's performance on a test set, nor are there any acceptance criteria related to diagnostic accuracy, statistical metrics, or human reader performance. The "acceptance criteria" for this device are implicitly tied to demonstrating substantial equivalence to predicate devices through material testing and design comparison to ensure safety and effectiveness.
In summary, none of the requested information regarding AI/ML performance, sample sizes for test/training sets, expert ground truth, adjudication methods, or MRMC studies can be extracted from this document, as it pertains to a traditional physical medical implant, not an AI/ML diagnostic or assistive device.

Dear Ms. Komiyama:
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. 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); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820);
{1}------------------------------------------------
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). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm for the CDRH's Office of Surveillance and Biometrics/Division of Postmarket Surveillance.

comes in nine sizes and the surgeon has the option to trim the implant to fit the patient's need. The implant is provided sterile or non-sterile, as either the "Left" or "Right" side.
PREDICATE DEVICE IDENTIFICATION
The ePTFE-Coated Auricular Implant is substantially equivalent to the following predicates:
| 510(k) Number | Predicate Device Name / Manufacturer | Primary Predicate |
|---|---|---|
| K863939 | Porex Ear Prosthesis / Porex Medical | |
| K141027 | Implantech ePTFE Facial Implants / Implantech Associates | |
| K002886 | Implantech Composite Facial Implants / Implantech Associates |
SUMMARY OF NON-CLINICAL TESTING
No FDA performance standards have been established for the ePTFE-Coated Auricular Implant. Patient-contacting material was subjected to biocompatibility testing in compliance to ISO 10993-1 Biological evaluation of medical devices — Part 1: Evaluation and testing within a risk management process. Testing included cytotoxicity, irritation, sensitization, acute systemic toxicity, material-mediated pyrogenicity, implantation, and chemical characterization.
Bond strength between the silicone elastomer and the ePTFE outer layer was evaluated to confirm that the effects of aging, repetitive sterilization (dry heat and steam) and the white pigment in the silicone elastomer do not adversely affect the silicone/ePTFE mechanical bond of the ear implant.
EQUIVALENCE TO PREDICATE DEVICES
Implantech believes that the ePTFE-Coated Auricular Implant is substantially equivalent to the predicate devices based on the information summarized here:
The subject device has the same intended use and target population as the Porex Ear Prosthesis device cleared in K863939. The subject device uses similar or identical materials and similar manufacturing processes as the Implantech ePTFE Facial Implants cleared in K141027 and the Implantech Composite Facial Implants cleared in K002886. The main differences in design between the Porex Ear Prosthesis and the subject device include:
- Two-piece design vs one-piece design ।
- -Open framework vs trimmable single-piece design
- -High density propylene vs ePTFE/silicone composite
CONCLUSION
The ePTFE-Coated Auricular Implant is considered substantially equivalent to the predicate devices based on the identical indications for use, and similar technological characteristics. Based on the testing performed on the patient-contacting material, it can be concluded that the subject device does not raise new issues of safety or efficacy compared to the predicate devices.
