Intended Use

Duralastic Nasal implants are intended for use in augmentation and reconstruction of the nasal contour during rhinoplasty. They are intended for insertion via an intraoral or nasal sill incision.

To augment or reconstruct the nasal contour

Device Description

Duralastic Nasal implants are "L" shaped or straight with concave convex dorsal aspect which reached from the alar catilage to the radix. These silicone elastomer rubber implants are made from specially formulated silicone elastomers designed for implantation. The LSR 30 Implant Grade elastomer is Masterfiled at FDA and has been thoroughly tested for biocompatibility, mutagenicity, carcinogenicity, and cytotoxicity. These referenced material characterizations are found in Applied Silicone's Master File MAF-562 and Nusil Technologies's MAF 612 for their MED 4211 Silicone Rubber -Unrestricted. The Duralastic Nasal Implants will be provided sterile and nonsterile. Several biocompatible pigments are used to make the white and flesh tone versions of these implants.

AI/ML Overview

I am sorry, but the provided text does not contain the information required to answer your request regarding acceptance criteria and a study proving a device meets them. The document is a 510(k) summary for Duralastic Nasal Implants from 1997, and it focuses on product description, substantial equivalence to a predicate device, intended use, physical/chemical properties, sterilization, and packaging. It also includes the FDA's clearance letter.

Specifically, the document does not include:

  • A table of acceptance criteria and reported device performance.
  • Details about any specific study (clinical or otherwise) designed to prove the device meets acceptance criteria.
  • Information on sample sizes, data provenance, expert ground truth establishment, adjudication methods, MRMC studies, standalone algorithm performance, or ground truth types, as these are typically associated with performance evaluations of diagnostic or AI-driven devices, not simply material properties and substantial equivalence claims for an implantable medical device like this one.

510 (k) SUMMARY

PRODUCT DESCRIPTION

Duralastic Nasal implants are "L" shaped or straight with concave convex dorsal aspect which reached from the alar catilage to the These silicone elastomer rubber implants are made from radix. specially formulated silicone elastomers designed for implantation. The LSR 30 Implant Grade elastomer is Masterfiled at FDA and has for biocompatibility, mutagenicity, thoroughly tested been carcinogenicity, and cytotoxicity. These referenced material characterizations are found in Applied Silicone's Master File MAF-562 and Nusil Technologies's MAF 612 for their MED 4211 Silicone Rubber -Unrestricted. The Duralastic Nasal Implants will be provided sterile and nonsterile. Several biocompatible pigments are used to make the white and flesh tone versions of these implants.

SUBSTANTIAL EQUIVALENCE

Duralastic Nasal Implants are SE to Allied Biomedical Nasal Implants, K971481. They will be produced in the exact sizes and shapes as the Allied Predicate device.

INTENDED USE

Duralastic Nasal implants are intended for use in augmentation and reconstruction of the nasal contour during rhinoplasty. They are intended for insertion via an intraoral or nasal sill incision.

PHYSICAL AND CHEMICAL PROPERTIES

The Duralastic Nasal implants are manufactured from Applied Silicone's LSR-30 part # 40029 which is a platinum cured dimethyl polysiloxane system. All chemical characterizations are found in Applied Masterfile MAF-562. Titanium Oxide and Iron Oxide pigments are added to these implants when ordered by the physician. These pigments are tested for cytotoxicity. The proposed Duralastic Nasal Implants will also be manufactured utilizing Nusil Technologies' MED 4211 Unrestricted Silicone Rubber Masterfiled at FDA under Nusil MAF 612.

The physical properties are: Durometer 30 Shore A, Elongation 650%, Tensile Strength 950 PSI, tear strength Tear Die C 150 PSI,

510(k) Summary Continued

Specific Gravity 1.12, Modulus 300 PSI at 200% Elongation, Surface Smooth and Textured.

STERILIZATION CYCLE

Duralastic Nasal Implants are sterilized via gamma radiation cycles of 2.5 - 4.2 Meqarads. The validation of this cycle will be designed and validated by a private contractor. Sterigenics Corporation will be the contract gamma sterilizer. The validation will use Method 1 Testing as defined in the ANSI/AAMI/ISO 1137-1994 "Sterilization of Health Care Products -- Requirements for Validation and Routine Control - Radiation Sterilization." In the event the products are shipped nonsterile a validated heat cycle will be recommended to the user.

PACKAGE DESCRIPTION

The proposed Duralastic Nasal Implants will be double peel pouched in Tyvec pouches and provided sterile and non sterile. These pouches will be in turned packaged in corrugated boxes for shipping.

Re: K973573 Trade Name: Duralastic Anatomical Nasal Implants Regulatory Class: II Product Code: ESR Dated: September 15, 1997 Received: September 19, 1997

Dear Ms. Richardson:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). 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.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirements , as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
