Dear Saakshi Arora-Tice:

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 (the 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 available 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.

# Summary of Non-Clinical Testing

# Biocompatibility

MENTOR™ has completed a Biological Evaluation Matrix (BEM) focusing on a proposed material change and identifies and characterizes the materials based on their type and the duration of patient contact. The Dip Coat has direct patient contact for either a limited duration (≤ 24 hours) for sizers or long-term (>30 days) for implants. Regardless of the device's size, all devices use about the same amount (1-2 drops, <0.02 grams) of Dip Coat material. The proposed alternative is NuSiI™ MED6-6605 - RTV Silicone, which is already used in other MENTOR™ Saline-Filled and Spectrum Adjustable Breast Implants and Saline Sizers. These implants were first approved by the US FDA on May 10, 2000 (PMA Number P990075) and are marketed outside the US (CE mark in 1995) with no significant safety issues related to the silicone.

MENTOR™ has also conducted a Biocompatibility and Toxicology Risk assessment for the proposed sizer devices dip coated with MED6-6605. The proposed dip coat material MED6-6605 is already used in other MENTOR™ Saline-Filled and Spectrum Adjustable Breast Implants and Saline Sizers. A detailed biocompatibility risk assessment was conducted on these devices which concluded that these devices present no significant biocompatibility risk when used as long-term implants or limitedduration sizers. Based on existing chemical, biological data and history of clinical use, Spectrum and Saline filled Breast Implants and Sizers present no significant risk of adverse biologic reactions in patients.

Table 2 provides a summary of the biological tests of the dipcoat material (MED6-6605) which is already used in MENTOR™ saline-filled implants and sizers (P990075). Table 3 provides a summary of the biological tests of the sizer (other than dipcoat material).

# Performance Data

MENTOR™ has completed the performance qualification (PQ) for the use of the alternate MED6-6605 for the Dip Coat application process located in MENTOR™ Irving, Texas Site. The PQ acceptance criteria defined in the PQ Protocol were satisfactorily met (see Table 4).

| Attribute Requirement | Acceptance Criteria | PASS/FAIL & Result / Conclusion |
|-----------------------------------------------------|---------------------------------|-----------------------------------------------------------------------------------------------------------|
| In Process Visual<br>Inspection | Yield ≥ Product Target<br>Yield | PASS<br>In Process Visual inspection on each of the lots showed a Yield<br>above the Product Target Yield |
| Visual Inspection after 2X<br>Sterilization Process | C=0 / 100% Pass | PASS<br>Visual inspection after 2X Sterilization Process showed 100%<br>acceptable Dip Coat. |

#### Table 4: Summary of testing and conclusions of the Dip Coat Process PQ Testing

As a result of this qualification activity, it is concluded that the Dip Coat process using MED6-6605 has successfully passed PQ activities based on the acceptance criteria. This PQ established with objective evidence the Dip Coat Process, under anticipated conditions, can consistently produce products that meet all predetermined requirements. Based on the satisfactory results, it can be concluded that alternate material MED6-6605 is suitable material for Dip Coat application and can be released for commercial manufacturing once the regulatory approvals are obtained.

MENTOR™ has conducted Sizers Reprocessing Product Lifetime testing to verify that MED6-6605 (NuSil™ Technology) can adequately function as a suitable Dip Coat material and perform as intended over the product lifetime of MENTOR™ gel sizers manufactured at MENTOR™ Texas. Based on the satisfactory results (see Table 5), it can be concluded that alternate material MED6-6605 functioned as a suitable dispersion coating (dip coat) material over the expected product lifetime of MENTOR™ gel sizers manufactured by MENTOR™ Texas.

| Criteria for Success<br>Requirements | Acceptance Criteria | Test Results<br>(PASS/FAIL)? |
|--------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------|------------------------------|
| Visual examination | The dip coat on each device shall maintain full integrity and adherence of the<br>dipcoat to the substrate posterior side of the sizer. | PASS |
| | There shall be no evidence of leakage of gel or like fluid in and around the dip<br>coat at the injection hole site. | PASS |
| | Dip coat shall show no sign of cracking, delamination, or any leakage from fill<br>hole. | PASS |

# Table 5: Summary of testing and conclusions of the Sizers Reprocessing Product Lifetime testing

There was no evidence of dip coat failure, nor were any leakages detected at the dip coat injection site of any of the test samples. Therefore, MED6-6605 successfully functioned as a suitable

{8}------------------------------------------------

dispersion coating (dip coat) material over the expected product lifetime of MENTOR™ gel sizers manufactured by MENTOR™ Texas.

# Summary and Conclusion

The combination of successful performance testing (passing all acceptance criteria), biocompatibility, unchanged indications for use, and unchanged technological characteristics, demonstrate substantial equivalence of the proposed devices to the predicate devices. The conclusions drawn from the nonclinical testing (discussed above) demonstrate that the proposed sizer devices dip coated with MED6-6605 from Nusil™ is as safe, as effective and performs as well as the predicate devices dip coated with DC 92-009 from Krayden/ Dow.
